@@Tanks-In-Space I had to learn about them as customers regularly didn't know how to take them out and one of our steps was to have the customer remove the cable. I take every opportunity to learn hands on then that way I can instruct people over the phone as I can picture it in my head and give very detailed explanations. OH WHAT FUN THAT WAS.
It is about 20 years ago by now, but they look like those optical thingys I stuck into a switch in the early 2000’s to connect a fibre pair when I was a server/network admin. I have been out of that kind of business for about 15 years, so I don’t remember exactly how they looked.
I used to use them a few years ago, when I was doing some work for Allstream. I'd be in a data centre, with the fibre connecting to a Ciena media converter and then copper to a Cisco router, which the customer then connected to. The SFP had to match the fibre type and wavelength for the connection.
Hi Thio. Your YT script for translating and dubbing it on another language is awesome. So many people can enjoy your content even without knowing English. Just a heads up: In my native language (Brazilian Portuguese) "RJ45" are being translated as "Rio de Janeiro 45". I don't know how you can fix this since is an auto translation issue, but it messes with the timing of dubbed lines.
I use these at work all the time :) As you said, it's frustrating how expensive even regular SFP+ is compared to just straight up RJ45, it's more of a problem for enthusiasts with a use case for them than your average home user.
Years ago i worked in an IT infrastructure renovation project and the guys in networking called them GBIC, but i actually think they were referring to SFP. I had a lot of this things laying around. If i remember correctly we used them to connect a switcher to the fiber optic box and than connect all the floor switches together. Standard Ethernet cables for the other hosts in the network.
GBIC ("gigabit interface converter") was the name of similar modules for Cisco (and others?) switches. I think they've been obsolete for nearly 20 years now.
@@bjornroesbeke GBICs were used on the 3550 Series (EOS 2006). They switched to SFP at the 3560 Series which were released in 2004 (EOS 2016). Of course, like anything network related, adoption of the new switches with SFP took years in many cases.
@@pyp2205 i use them at home... because i can. i used to have 4 rj45 from my adsl router until i bought a 5g adsl version. it has 4 rj45 and one sfp+ port. so me being me, i got rid of the 4 rj45 and replaced it with one fibre optic to sfp+ connector to my L2 home network switch.. lets just say i can see a combined throughput of over 200mb/s to the router...
"never look into the end of a fiber cable". THANK YOU for this warning! I have no occasion to walk into datacenters, but this may happen and I could be tempted to do it... now I know! This made my day.
Anyway - we do have quite a number of those devices at work. Mostly multimode. The light in the multimode transcievers is actually visible if you use your phone camera, it helps quite a lot when you try to figure out which side that's the dark side.
2:45 the SFP ports are also often used for switch stacking, allowing multiple similar switches to share a backplane, making for extremely performant expandability and throughput a Ross the entire stack without the limitations of plain trunk ports.
Home PC devices now come with 2.5/10GPS connections so if you're mating to a switch with SFP+ ports, make sure to check your transceiver specs to see if they support intermediate data rates, most support only 1/10, not 2.5/5.
As worked with fiber optics in Telecommunications, just a pro tip. Never look directly into the tip of the fiber cable connected to any equipment (specially industry/corporate grade) . Power ranges of these equipment can be easily in range of above +20 db and that invisible light running through that fiber can burn your fingers let alone fry your eyeballs if looked directly, you can literally see sparks through the plastic tip if touched to a cleaning cloth dipped in alcohol.
A couple years ago I bought a QNAP TS-332X Home NAS specifically bc it came with the 10GbE SFP+ port. Added an inexpensive, older generation 10GbE PCIe card to my workstation, and connected to NAS via a copper "TwinAx" cable. Paid $35 for the PCIe card and cable on eBay.
We have just upgraded our server and switches where I work which is about 250 feet +- between the switches. With that we were already having CPU and Disc usage issues bumping up to %100. Our IT company said we needed these for the longer runs. Since we run our own lines, we needed to know what these were and how to assemble them. Thanks because this was perfect for us. Passed it off to my boss and he was thankful as well.
I have 4 Ubiquiti 10 port EdgeSwitches. 2 of the 10 are SFP cages. So, I bought 8 1000BASE-T copper transceivers, because I wanted to be able to use all of the ports if needed. I was surprised at the amount of heat that was coming off of the SFP modules. I read that they can get hot. But geeezzz! I recently bought a Grandstream GWN7803 (28 ports in all) L2 switch, which includes 4 SFP cages. They're nice to have, if you need them.
Great to see the language feature at work again! Just a heads up for future translations. You may want to use the ISO 4217 standard codes when talking about currencies, so it doesn't interpret '$' as a different currency.
Not all ONU's are made like that. Zhone has models where the transceiver has to be installed, and plugs into an LC connector which than plugs into a terminated SC connection inside the enclosure where the fiber loop is
Here in Switzerland, every house with FTTH has an SFP+ connector for 10gbps connections. Nearly every house (in cities mostly) have a wall plug for SFP+ which connects to the router. Just a lil funfact, and why this connector is actually not uncommon at all in Switzerland! With some ISPs (Init7 for instance), you can actually get 25gbps with SFP28.
what do you mean? This are just data links and have nothing to do with loadbalancing. This is the physical layer of the osi model. Loadbalancing it way more up in the model.
A sfp module exist either as rj45 or as fibre. That is the sense of this module that you can decide self if you need copper or fibre. It depends on length of cable. Copper cannot bridge more than 100m. You will need it on each cisco switch and some of commodity. And PoE is availabe, that is the sense of SFP+, it delivers 60 watts instead of 30 of normal sfp.
Well, being a telecom engineer I use SFPs daily :-) Of course I knew the most you said, but still it was interesting to me. I can add that not only SFPs can be incompatible with your equipment, they can be different at all, like Ethernet SFP, used for switches, of STM SFP, used in telephony connections. They also can use separate fibers for transmission and receiving data, as well as they can use single fiber, but use different wavelength signals for different directions. SFP-to-Ethernet is what we use for switches that have SFP ports only and we need to connect it to "copper" equipment.
These modules have another thing to check - the cable length. Some models officially support shorter runs than expected 100 meters, it can be as short as 30 meters instead.

Correction: at 1:50 you show a chart of latencies between connections and say that "SFP has lower latency than RJ45" Which isn't accurate to the chart. The left column shows "10GBaseT SFP" Which is an rj45-sfp adapter, not direct rj45-rj45(technically 8p8c but that's besides the point). It is the adapter from the rj45 to SFP that is causing the increased latency, vs "direct attach copper", pure sfp to sfp no adapter. I've yet to see any evidence that pure SFP DAC has lower latency than pure RJ45, and at least one video on youtube suggests the opposite.
they're expensive compared to the much more common 1Gb (or even 2.5Gb) switches but for 5 or 10GbE the mikrotik switches with all SFP+ ports are among the cheapest you can get by far. In fact, I wish consumer grade multigig would move to SFP+ instead of RJ45 because of this exact reason. Everytime I have to connect something RJ45 especially at multigig speeds, the switches i have to get are triple the price.
The compatibility issue you saw is strangely sinister. Inside the sfp chipset is data containing serial number, manufacturer, etc. Network gear manufacturers sometimes hard code their devices to look for only their own sfp’s. Most of the big enterprise players have a command to tell their equipment not to do that, but after you run that command, their support will stop at the sfp port level. Also, your example 10gig throttling down to 1gig is simply because the equipment is inexpensive and doesn’t have enough queue memory to slam 10gig frames at a 1 gig port. This used to be common behavior, even on enterprise gear, back when nothing had enough queue size.
0:21 Oi, a tradução meio que levou ao literal o RJ45 como “Rio de Janeiro 45” (pois a sigla do estado no Brasil é a mesma), as pessoas geralmente falam “RJ45” no português.
I used the SFP+ when I was working for an ISP. One coming in from each of the backbone providers, into the transparent firewalls that I built and ran for the ISP. And then one each going out of the firewalls, and again one each going into the big Cisco router. I think that we also had a few going from the router into the big switches.
I work with enterprise gear on the daily, and whilst I've never set up SFP or plugged it in, I'm very aware of it and know what it is. I'm a systems engineer not a network or cable guy. And I had no idea about the different types nor speeds. Cheers for that!
I've been lucky to be able to work with QSFP-DD (and soon OSFP), It is really cool tech and incredibly fast data rates, even considering that the 400G is divided across 8 channels. My company is making equipment for Cisco, Juniper, et al to test the electromagnetic radiation of their QSFP-DD hardware. When you have a server rack full of these modules, its basically a wall/array of antennae radiating at up to 50GHz, and neighboring racks can interfere with each other if not shielded properly.
I see active Optical SFP cables for sale and they mentioned 10 gb. But I wonder if they work at lower speeds in other words is 10 GB the upper limit or is it the only speed they work at? I'm thinking of hooking up a switch with 2.5 gigabit ports to a router that has a 10 gigabit port.
Excellent video : I have a quick question, Can we connect QSFP to ethernet directly or do we need to convert QSFP to SFP+ and another convertor from SFP+ to Ethernet?
Hi Thio, Quick question please. I have a new Qnap Qhora321 wired router for home use. And the firewall has 3 setting I need help with. FTP ALG, PPTP ALG, SIP ALG. For home use do I need to have any of these enabled? Thank You!
It auto switched to polish for me and I have to say, it's pretty amazing that you can do that now, but the constantly changing speed of the narrator is sometimes distracting. I feel like inserting a bit of a pause instead of slowing down the speech might be a good idea in some cases to make it "flow" better. There are some mistakes/things translated "too directly" where some context changes the word we would use in polish, but it's usabe. I still prefer to watch in english, but that was to be expected as I can hear the original in sync with the video and without any mistakes. Really nice!
When installing AV over IP encoders and decoders, sometimes all the ports become used, the bandwidth or power allowance is maxed out, so we have to stack switches to either increase the bank or add extra ports to the installation.
I hate the fact the audio track gets chosen automatically, even if I want to watch it in the original language. UA-cam did a bad job at implementing it.
The old timers I work with use the anachronistic term "gbic" to refer to SFPs. We have a wide variety of clients at our MSP. We recently installed a commercial StarLink dish at a rural client site as a secondary WAN. Being that this site has had several lightning strikes I opted to use a media converter to connect the RJ-45 from the starlink to the secondary WAN SFP port on their UDM Pro. Better to have a measure of electrical isolation than have their main router take a lightning strike again. I dug a burnt cable out of the wall when I ran the line too. 🤣🤣
We’ve had copper sfps weld into switches. So certain switches we only run fiber. The 2 sfps with a copper cable built in are called DAC (Direct Attach Copper). We use fiber for all the infrastructure where I work. Copper inside buildings with the exception of datacenter. All servers that support it are using fiber, some even using 10 or 25Gig.
Is there a way to turn the automatic change to the voicetrack off or so I need to change my youtube language to english? Because it is already starting to annoy me...
Was super disappointed with the ubiquiti unit. Didn’t support negotiating at speeds under 1gbps. Just needed to add one more port, didn’t need a small dummy switch. Turns out I needed a dummy switch
Hi, good video. Also the german translation generated is very odd. I switcht to english since if was that bad. Also some comments / facts that are WRONG 3:43: This sfp copper cable are called DAC or Twinax. There are active and passiv once. Usuably they are only sold up to 10m length. 4:50: VERY WRONG!! each sfp (whether it is optical, DAC or converter to RJ45) have vendor bit set. If the NIC or the switch accepts modules with different vendor bits is up to the firmware. On some switches you can enable different vendor sfp but it sets a marker and when you have trouble they will not support you if different vendor modules are installed. 5:26 DAC calbe or sfp copper cable as you call them ARE even more sensitive to vendor bit and active / passiv mode. You have a cable and maybe need the sfp module on one end have another vendor bit set then the other module on the cable. If you don't like to pay the overpriced version of the vendor there are sellers like FS other other where you get quality modules coded to you vendor. Also if you need big batch there are devices to "copy" the vendor bit. But it is VERY important to get quality modules. At last I will point out that with 40gbit and 100gbit there are cables called break out which can split 40g to 4x10g and 100g to 4x25g. But make shure you switch support the port split sice the cable only is not enougth to split the port up. Also since you do not point it out, optical cable modules have also a release clip. And since you showed it in the video there are modules with one fiber port and some with two fiber ports. The two are called duplex and the one with one are simplex. Make shure to order the right optical cable. Also in optical there are sinple mode and multi mode which can not be mixed on the sides! Also there are single mode and multi mode cable. On the FS Website there is cmmunity and blog with MUCH inforamation about fiber and the other type. Please see there for a mode detail view in this high complex field bevor you order the wrong parts.
The technology behind automatic translations is impressive, but the audio speeding up and down to match the original speed is kinda weird sounding. Also it seems like sometimes it's just translating word by word rather than full phrases and it ends up with a phrase that doesn't quite make sense in Polish, but I was surprised how it handled proper nouns.
I use these all the time both at work and at home and at my friends and families houses too. I've got a 10GB NIC for my desktop to interface to my fiber internet to get my advertised speeds from my ISP. I'd like to use fiber but the router from the ISP only has a 10GB copper jack 😞
Translation feedback/rant below: its very uncanny seeing everything translated to polish. also the voice translation is not very good, for example at the very begining it said "it is used in situations when you want to sprint for long distances" also i just prefer your voice over the AI. AND the voice is also very speed-up, because polish words are usually longer. (tho if a native speaker were talking, it could be said in the same amount of time (or even less) without the need to speed up their voice, as the automatic translation is using pretty basic phrases. Google Translate notorious for being bad with slavic languages.) anyways, im gonna use the original audio track, as even if the translation was perfect, it dislike the TTS PS: also in the description to the teesprings link, it says "Towar", which means "Cargo", also it is slang for drugs PPS: does anyone know how to disable youtube automatically setting the audio track, title, and description to polish? i want it to use english, if thats the original language, but still want polish in UI, and for it to not translate polish videos to english. I have set on my google account 3 languages: 1. Polish 2. English (UK) 3. English (US) but when i open your videos, it translates everything to polish, and i have to manually select the audio track to english. *that being said* , i absolutely appreciate the effort you are putting in, thats 100 times more effort than an average youtubers bothers with, and im sure there are many people who don't mind these issues, however for me, its just not all that great, but don't think im hating on you or anything :p, i absolutely love this channel, you gave me countless hours of entertainment and information !!!
I installed a 24 port Cisco Switch. and installed 4 SFP Connectors. This gives me 28 channels. The Cable Modem is on one. A bunch of cameras, RJ-45 in every bedroom, 2 in the office 1 for DVR, and one for my NAS Drive. So I really needed the system up and running with the 4 extras. Not done yet.
Its just an SFP. We use them all the time in Enterprise switches for connecting fiber and far less less commonly RJ-45. I have a Cisco switch in my room and it has 4 SFP slots. I was planning on running fiber from my room to the router to replace the existing Ethernet over Coax and I would use SFPs on both ends.
The problem might be with your 10g pc connection to the switch and then onto the Apple TV. You might be running into issues with the larger data frames and packet sizes in 10gb. On the pc you could match the transmit and receive buffer to that of a 1g connection. I have run into this problem before with NDI
I have often used those, when setting up connections from a carrier to a data centre. With fibre, there are a variety of models, depending on the fibre connection. There can be single or double fibre versions, single or multimode and any of those with a variety of wavelengths (infrared "colour") to consider. Also, you showed a switch with several copper connectors and 2 SFP connections. When there are 2 or 4 connections, separated from the rest of the switch, they're generally used for upstream connections and will typically be faster than the rest of the switch. For example, years ago, I used to work with 24 port 100 Mb switches, that also had 2 Gb ports. Those Gb ports could be connected to a Gb switch, for large networks. The same holds with the speeds commonly found these days.
I had recently picked up the TP-Link adapter in your video but hadn't gotten around to install it in my UDM Pro. When you said it was incompatible, it had me concerned and I initially had some difficulty getting it to work. But, I found it does if I set the #10 SPF+ port as a LAN port. I really want it to work as a WAN so that I can use my phone as a backup Internet connection.
Even with DACs, you can run into issues when you mix and match vendors. The host device (device with SFP port) and the SFP itself always perform a negotiation, even if there's no actual logic needed for transceiving the signal (because it's just a copper cable). Some devices are more picky than others, on some switches you have to enable a config option to allow unsupported transceivers (ones from a different brand than the switch). Using SFPs from a generic brand can be hit and miss. There's one brand, they're called Flexoptix out of Germany that offers programmable universal transceivers that can be programmed to emulate the behaviour of any other SFP, they mostly work well in my experience. And they're hella cheap compared to the official vendor ones - an original Cisco SFP might literally be 10x the price of a reprogrammable Flexoptix SFP. Then again, the box used to reprogram SFPs is something like 1,5k, so only affordable to businesses that do a lot of installations.
I'm sometimes being in an area with a switch rack. I examined the switches inside that and noticed that most of them were not looking like the Ethernet cable plugs I know. Some plugs(maybe) had two cables attached to them. I guessed that there could be fiber there, but I didn't know much idea. Now I know that the rack was full of SFP's 🤯
I have to plug in one of these SFP+ adapters for my modem's fiber internet connection. There is one 10 GbE port on my modem, which I can break out to other devices using a 10 GbE switch. I use a TP-Link TL-SX105 for this purpose.
When I was in the military we had a connector that had about 120 pins in the connector and could transfer almost a terabyte of information in less than a minute however this requires a special setup to work properly and even then it's not particularly easy to use or get maximum speeds during transfer.
Hey mr ThioJoe I got a question, you made in the past videos about android and ios options and tips n tricks, do you happen to know about ADB and how to use it?
Useful info, my use case is an old enterprise switch. I was originally going to use transceivers, but think I'm going to get expansion cards for the two systems getting 10 gigabit connections.
Partitioning a SSD good or bad?? After swapping my hhd to ssd i am getting a lot of blue screen errors (6 different type of errors), even installing the OS 4 times still getting errors.
@ThioJoe The autodub for Brazilian Portuguese is incorrectly changing the name "RJ45" to "Rio de Janeiro 45", since RJ is an acronym to the state of Rio de Janeiro in Brazil
We have a few of these in a few businesses we look after as you said it tends to be SFP from Switch to switch put we also have teamed SFP into host servers to run a 20gbps uplink to those.
"...totally overkill for a home use..." I trunk VLANs (between switches) over multi-mode fiber at home - and have a set of spare copper SFPs for use on UTP cables parallelling the fiber if something goes bad.
also bare in mind if you do this on more switches then spanning tree or it's new rstp versions comes into play. Basicly have redundant pathes in the network (which is a big no no in ehternet) and the spanning tree blocks them so no loop ocours and if a link goes down spanning tree will recalculate and enable a redundant link.
@@alexanderg9106: The copper SFPs are spares - only one SFP can be plugged in at a time anyway, and I have them so no other port configuration needs to be changed to swap between SFP media types. There is only one trunked port coming in to any of my peripheral switches.
@@alexanderg9106: And rather than getting fancy with redundant links and equipment, I just swap out failed parts (I have spare switches for everything I run) - It is a home environment after all. 😁
"Rare use case"? As a home lab user, I've got a DAC between my NAS and switch and budget server and switch, so both have a 10G connection to each other.
Uma falha na versão em português, creio que está sendo feita automaticamente: Quando se menciona o conector RJ-45, o apresentador diz "Rio de Janeiro 45", pois, coincidentemente RJ é a sigla do estado do Rio de Janeiro.

We have just upgraded our server and switches where I work which is about 250 feet +- between the switches. With that we were already having CPU and Disc usage issues bumping up to %100. Our IT company said we needed these for the longer runs. Since we run our own lines, we needed to know what these were and how to assemble them. Thanks because this was perfect for us. Passed it off to my boss and he was thankful as well.
I have 4 Ubiquiti 10 port EdgeSwitches. 2 of the 10 are SFP cages. So, I bought 8 1000BASE-T copper transceivers, because I wanted to be able to use all of the ports if needed. I was surprised at the amount of heat that was coming off of the SFP modules. I read that they can get hot. But geeezzz! I recently bought a Grandstream GWN7803 (28 ports in all) L2 switch, which includes 4 SFP cages. They're nice to have, if you need them.
Yup same experience for me, to the point where its so hot you could genuinely get burnt.
If you use fiber transceivers or direct attach copper, they wont get as hot
Great to see the language feature at work again! Just a heads up for future translations. You may want to use the ISO 4217 standard codes when talking about currencies, so it doesn't interpret '$' as a different currency.
As someone who does FTTH fiber splicing, i am very familiar with SFP connectors. They are super useful to use in so many situations.
Dont the ONU just have sc/apc built in?
Not all ONU's are made like that. Zhone has models where the transceiver has to be installed, and plugs into an LC connector which than plugs into a terminated SC connection inside the enclosure where the fiber loop is
@@ericmattson9352 cool thanks
Here in Switzerland, every house with FTTH has an SFP+ connector for 10gbps connections. Nearly every house (in cities mostly) have a wall plug for SFP+ which connects to the router.
Just a lil funfact, and why this connector is actually not uncommon at all in Switzerland!
With some ISPs (Init7 for instance), you can actually get 25gbps with SFP28.
They are commonly used between switches in the same network as a load balancer for the switches. Pretty clever idea.
what do you mean? This are just data links and have nothing to do with loadbalancing. This is the physical layer of the osi model. Loadbalancing it way more up in the model.
A sfp module exist either as rj45 or as fibre. That is the sense of this module that you can decide self if you need copper or fibre. It depends on length of cable. Copper cannot bridge more than 100m. You will need it on each cisco switch and some of commodity. And PoE is availabe, that is the sense of SFP+, it delivers 60 watts instead of 30 of normal sfp.
Well, being a telecom engineer I use SFPs daily :-) Of course I knew the most you said, but still it was interesting to me.
I can add that not only SFPs can be incompatible with your equipment, they can be different at all, like Ethernet SFP, used for switches, of STM SFP, used in telephony connections. They also can use separate fibers for transmission and receiving data, as well as they can use single fiber, but use different wavelength signals for different directions. SFP-to-Ethernet is what we use for switches that have SFP ports only and we need to connect it to "copper" equipment.
Hello 👋🏻 Happy New Year 🎆
Excellent new year, good to be back
@@ThioJoe 🥳🎉
this video is pretty interesting.
by the way, i hope you get to 3 million subs.
happy new yaer!🥳🎄❄🎉 and christmas
I'm a network engineer, so this is interesting to see it framed this way. :)
These modules have another thing to check - the cable length. Some models officially support shorter runs than expected 100 meters, it can be as short as 30 meters instead.
this^ not all SFP's have the power to blast fiber down a couple KM's run, some can only do a couple meters.
What app is that you showed to switch the sfp transfer rate? At 4:30?
I was an intern in networking for a month last summer, I did indeed see those connectors and also used them
adoro il tuo software per tradurre i video, è molto utile per i video classici ma per i Roleplay è un casino, ci vorrebbe di migliorare il file aggiungendo le varie emozioni in modo che possa emularle
good one, the last video before bed and clearest i watched :)
Correction: at 1:50 you show a chart of latencies between connections and say that "SFP has lower latency than RJ45" Which isn't accurate to the chart. The left column shows "10GBaseT SFP" Which is an rj45-sfp adapter, not direct rj45-rj45(technically 8p8c but that's besides the point). It is the adapter from the rj45 to SFP that is causing the increased latency, vs "direct attach copper", pure sfp to sfp no adapter. I've yet to see any evidence that pure SFP DAC has lower latency than pure RJ45, and at least one video on youtube suggests the opposite.
I have these on my MikroTik 10Gb switch. They can be a little expensive but they're awesome! My main use is accessing my 10Gb NAS. 😁
they're expensive compared to the much more common 1Gb (or even 2.5Gb) switches but for 5 or 10GbE the mikrotik switches with all SFP+ ports are among the cheapest you can get by far. In fact, I wish consumer grade multigig would move to SFP+ instead of RJ45 because of this exact reason. Everytime I have to connect something RJ45 especially at multigig speeds, the switches i have to get are triple the price.
The compatibility issue you saw is strangely sinister. Inside the sfp chipset is data containing serial number, manufacturer, etc. Network gear manufacturers sometimes hard code their devices to look for only their own sfp’s. Most of the big enterprise players have a command to tell their equipment not to do that, but after you run that command, their support will stop at the sfp port level.
Also, your example 10gig throttling down to 1gig is simply because the equipment is inexpensive and doesn’t have enough queue memory to slam 10gig frames at a 1 gig port. This used to be common behavior, even on enterprise gear, back when nothing had enough queue size.
0:21 Oi, a tradução meio que levou ao literal o RJ45 como “Rio de Janeiro 45” (pois a sigla do estado no Brasil é a mesma), as pessoas geralmente falam “RJ45” no português.
Só por causa desse erro de dublagem, vou chamar o cabo Ethernet de "Cabo Rio de Janeiro", kkkkk.
I used the SFP+ when I was working for an ISP. One coming in from each of the backbone providers, into the transparent firewalls that I built and ran for the ISP. And then one each going out of the firewalls, and again one each going into the big Cisco router. I think that we also had a few going from the router into the big switches.
In some places, you can get 10Gbps residential internet these days :)
@@ArthursHDyou probably can, but not where I live. You are still lucky to have 10Mbps service, unless you are on StarLink.
I work with enterprise gear on the daily, and whilst I've never set up SFP or plugged it in, I'm very aware of it and know what it is. I'm a systems engineer not a network or cable guy.
And I had no idea about the different types nor speeds.
Cheers for that!
I've been lucky to be able to work with QSFP-DD (and soon OSFP), It is really cool tech and incredibly fast data rates, even considering that the 400G is divided across 8 channels.
My company is making equipment for Cisco, Juniper, et al to test the electromagnetic radiation of their QSFP-DD hardware. When you have a server rack full of these modules, its basically a wall/array of antennae radiating at up to 50GHz, and neighboring racks can interfere with each other if not shielded properly.
I see active Optical SFP cables for sale and they mentioned 10 gb. But I wonder if they work at lower speeds in other words is 10 GB the upper limit or is it the only speed they work at? I'm thinking of hooking up a switch with 2.5 gigabit ports to a router that has a 10 gigabit port.
Excellent video : I have a quick question, Can we connect QSFP to ethernet directly or do we need to convert QSFP to SFP+ and another convertor from SFP+ to Ethernet?
He looked into the cable and he saw the entire internet. All at once.
When I saw this video in my recommended and read the title I said to myself "Don't gaslight me Thio I know what that is"
What I learned in this video: cool network related sfc thingy, haha funny laser coming out of cable
I’ve actually seen some of these in old switches at my secondary school today! It had a fiber connection. Also seen two QSFP+ cables in the IT room.
Finally! A niche computer part!
thank you for Polish dubbing, I feel like the translation isn't very good, but it's not bad aswell
Hi Thio, Quick question please. I have a new Qnap Qhora321 wired router for home use. And the firewall has 3 setting I need help with. FTP ALG, PPTP ALG, SIP ALG. For home use do I need to have any of these enabled? Thank You!
In France we have sometimes a Fiber SFP on the home modem provided by the ISP (generaly when the modem is compatible with DSL and Fiber).
It auto switched to polish for me and I have to say, it's pretty amazing that you can do that now, but the constantly changing speed of the narrator is sometimes distracting. I feel like inserting a bit of a pause instead of slowing down the speech might be a good idea in some cases to make it "flow" better. There are some mistakes/things translated "too directly" where some context changes the word we would use in polish, but it's usabe. I still prefer to watch in english, but that was to be expected as I can hear the original in sync with the video and without any mistakes. Really nice!
When installing AV over IP encoders and decoders, sometimes all the ports become used, the bandwidth or power allowance is maxed out, so we have to stack switches to either increase the bank or add extra ports to the installation.
I hate the fact the audio track gets chosen automatically, even if I want to watch it in the original language. UA-cam did a bad job at implementing it.
The old timers I work with use the anachronistic term "gbic" to refer to SFPs.
We have a wide variety of clients at our MSP. We recently installed a commercial StarLink dish at a rural client site as a secondary WAN. Being that this site has had several lightning strikes I opted to use a media converter to connect the RJ-45 from the starlink to the secondary WAN SFP port on their UDM Pro. Better to have a measure of electrical isolation than have their main router take a lightning strike again. I dug a burnt cable out of the wall when I ran the line too. 🤣🤣
We’ve had copper sfps weld into switches. So certain switches we only run fiber. The 2 sfps with a copper cable built in are called DAC (Direct Attach Copper). We use fiber for all the infrastructure where I work. Copper inside buildings with the exception of datacenter. All servers that support it are using fiber, some even using 10 or 25Gig.
Is there a way to turn the automatic change to the voicetrack off or so I need to change my youtube language to english? Because it is already starting to annoy me...
Was super disappointed with the ubiquiti unit. Didn’t support negotiating at speeds under 1gbps. Just needed to add one more port, didn’t need a small dummy switch. Turns out I needed a dummy switch
ThioJoe: You've never seen this before!
Comments: I work as a network engineer
Super information to me. Thank you.
The rj-45 switches with SFP ports are usually the uplink to supply a higher bandwidth
uplink for stacking master/slave, downlink for switch core connection
Nice naming scheme. Probably took inspiration from USB
5:43 yes Joe it does add up hugely for sure, the price of an all-new switch easy. lol good looks man just decided to upgrade to 10gigs was I suprised.
I'll not lie: I laughed loud when the TTS read "Rio de Janeiro 45"
Hi, good video. Also the german translation generated is very odd. I switcht to english since if was that bad.
Also some comments / facts that are WRONG
3:43: This sfp copper cable are called DAC or Twinax. There are active and passiv once. Usuably they are only sold up to 10m length.
4:50: VERY WRONG!! each sfp (whether it is optical, DAC or converter to RJ45) have vendor bit set. If the NIC or the switch accepts modules with different vendor bits is up to the firmware. On some switches you can enable different vendor sfp but it sets a marker and when you have trouble they will not support you if different vendor modules are installed.
5:26 DAC calbe or sfp copper cable as you call them ARE even more sensitive to vendor bit and active / passiv mode. You have a cable and maybe need the sfp module on one end have another vendor bit set then the other module on the cable.
If you don't like to pay the overpriced version of the vendor there are sellers like FS other other where you get quality modules coded to you vendor. Also if you need big batch there are devices to "copy" the vendor bit. But it is VERY important to get quality modules.
At last I will point out that with 40gbit and 100gbit there are cables called break out which can split 40g to 4x10g and 100g to 4x25g. But make shure you switch support the port split sice the cable only is not enougth to split the port up.
Also since you do not point it out, optical cable modules have also a release clip.
And since you showed it in the video there are modules with one fiber port and some with two fiber ports. The two are called duplex and the one with one are simplex. Make shure to order the right optical cable.
Also in optical there are sinple mode and multi mode which can not be mixed on the sides! Also there are single mode and multi mode cable.
On the FS Website there is cmmunity and blog with MUCH inforamation about fiber and the other type. Please see there for a mode detail view in this high complex field bevor you order the wrong parts.
The technology behind automatic translations is impressive, but the audio speeding up and down to match the original speed is kinda weird sounding. Also it seems like sometimes it's just translating word by word rather than full phrases and it ends up with a phrase that doesn't quite make sense in Polish, but I was surprised how it handled proper nouns.
I use these all the time both at work and at home and at my friends and families houses too.
I've got a 10GB NIC for my desktop to interface to my fiber internet to get my advertised speeds from my ISP. I'd like to use fiber but the router from the ISP only has a 10GB copper jack 😞
Maravilhoso conteúdo, obrigado por trazer em Português do Brasil🇧🇷
"You've Never Seen Before"
__Looks down at the network card in my pc with two of them.__
Me: "Nope never in my life"
Translation feedback/rant below:
its very uncanny seeing everything translated to polish.
also the voice translation is not very good, for example at the very begining it said "it is used in situations when you want to sprint for long distances"
also i just prefer your voice over the AI.
AND the voice is also very speed-up, because polish words are usually longer. (tho if a native speaker were talking, it could be said in the same amount of time (or even less) without the need to speed up their voice, as the automatic translation is using pretty basic phrases. Google Translate notorious for being bad with slavic languages.)
anyways, im gonna use the original audio track, as even if the translation was perfect, it dislike the TTS
PS: also in the description to the teesprings link, it says "Towar", which means "Cargo", also it is slang for drugs
PPS: does anyone know how to disable youtube automatically setting the audio track, title, and description to polish? i want it to use english, if thats the original language, but still want polish in UI, and for it to not translate polish videos to english.
I have set on my google account 3 languages:
1. Polish
2. English (UK)
3. English (US)
but when i open your videos, it translates everything to polish, and i have to manually select the audio track to english.
*that being said* , i absolutely appreciate the effort you are putting in, thats 100 times more effort than an average youtubers bothers with, and im sure there are many people who don't mind these issues, however for me, its just not all that great, but don't think im hating on you or anything :p, i absolutely love this channel, you gave me countless hours of entertainment and information !!!
I installed a 24 port Cisco Switch. and installed 4 SFP Connectors. This gives me 28 channels. The Cable Modem is on one. A bunch of cameras, RJ-45 in every bedroom, 2 in the office 1 for DVR, and one for my NAS Drive. So I really needed the system up and running with the 4 extras. Not done yet.
Its just an SFP. We use them all the time in Enterprise switches for connecting fiber and far less less commonly RJ-45. I have a Cisco switch in my room and it has 4 SFP slots. I was planning on running fiber from my room to the router to replace the existing Ethernet over Coax and I would use SFPs on both ends.
The problem might be with your 10g pc connection to the switch and then onto the Apple TV.
You might be running into issues with the larger data frames and packet sizes in 10gb.
On the pc you could match the transmit and receive buffer to that of a 1g connection. I have run into this problem before with NDI
What use case do you have for a switch? Definitely not something a lot of home users have. Genuinely curious.
Good stuff. I use fiber SFP, SFP+ and DAC and some RJ45 transceivers for 10G. Still, I learned some stuff today. Thanks.
7:46 i would recommend a MikroTik CSS326 (?) with 2 SFP+ and 24 RJ45 Ports for around 160€
Didn't you already do a video on this a while back?
Nope, I did make a video about that 'industrial ethernet cable', but this is an SFP connector, which is different
@ThioJoe I must be thinking of a different video, but I do remember you mentioned SFP+ in one of your previous videos
You forgot QSFP+ which can carry 40 or even 56Gbit, super cheap these days and can provide NVMe-like speeds. Great video, tho!
I have often used those, when setting up connections from a carrier to a data centre. With fibre, there are a variety of models, depending on the fibre connection. There can be single or double fibre versions, single or multimode and any of those with a variety of wavelengths (infrared "colour") to consider. Also, you showed a switch with several copper connectors and 2 SFP connections. When there are 2 or 4 connections, separated from the rest of the switch, they're generally used for upstream connections and will typically be faster than the rest of the switch. For example, years ago, I used to work with 24 port 100 Mb switches, that also had 2 Gb ports. Those Gb ports could be connected to a Gb switch, for large networks. The same holds with the speeds commonly found these days.
I had recently picked up the TP-Link adapter in your video but hadn't gotten around to install it in my UDM Pro.
When you said it was incompatible, it had me concerned and I initially had some difficulty getting it to work. But, I found it does if I set the #10 SPF+ port as a LAN port.
I really want it to work as a WAN so that I can use my phone as a backup Internet connection.
Even with DACs, you can run into issues when you mix and match vendors. The host device (device with SFP port) and the SFP itself always perform a negotiation, even if there's no actual logic needed for transceiving the signal (because it's just a copper cable).
Some devices are more picky than others, on some switches you have to enable a config option to allow unsupported transceivers (ones from a different brand than the switch).
Using SFPs from a generic brand can be hit and miss.
There's one brand, they're called Flexoptix out of Germany that offers programmable universal transceivers that can be programmed to emulate the behaviour of any other SFP, they mostly work well in my experience. And they're hella cheap compared to the official vendor ones - an original Cisco SFP might literally be 10x the price of a reprogrammable Flexoptix SFP.
Then again, the box used to reprogram SFPs is something like 1,5k, so only affordable to businesses that do a lot of installations.
I'm sometimes being in an area with a switch rack. I examined the switches inside that and noticed that most of them were not looking like the Ethernet cable plugs I know. Some plugs(maybe) had two cables attached to them.
I guessed that there could be fiber there, but I didn't know much idea.
Now I know that the rack was full of SFP's 🤯
I have to plug in one of these SFP+ adapters for my modem's fiber internet connection. There is one 10 GbE port on my modem, which I can break out to other devices using a 10 GbE switch. I use a TP-Link TL-SX105 for this purpose.
There's even VDSL2 Modems for SFP form factor so you can plug your DSL directly into your router/switch.
When I was in the military we had a connector that had about 120 pins in the connector and could transfer almost a terabyte of information in less than a minute however this requires a special setup to work properly and even then it's not particularly easy to use or get maximum speeds during transfer.
Hey mr ThioJoe I got a question, you made in the past videos about android and ios options and tips n tricks, do you happen to know about ADB and how to use it?
This is so weird hearing a Polish narrator over ThioJoe on autoplay xD
Useful info, my use case is an old enterprise switch. I was originally going to use transceivers, but think I'm going to get expansion cards for the two systems getting 10 gigabit connections.
Partitioning a SSD good or bad??
After swapping my hhd to ssd i am getting a lot of blue screen errors (6 different type of errors), even installing the OS 4 times still getting errors.
@ThioJoe The autodub for Brazilian Portuguese is incorrectly changing the name "RJ45" to "Rio de Janeiro 45", since RJ is an acronym to the state of Rio de Janeiro in Brazil
Lol oh man, thanks for pointing that out
You mentioned Latency, every FPS/RTS player will now rush and buy one :D
We have a few of these in a few businesses we look after as you said it tends to be SFP from Switch to switch put we also have teamed SFP into host servers to run a 20gbps uplink to those.
Was waiting for the next video to check out the audio tracks.
ThioJoe in Portuguese you have to use
R J45 because if you use RJ45 the voice on the video will say "Rio de Janeiro 45"
"...totally overkill for a home use..."
I trunk VLANs (between switches) over multi-mode fiber at home - and have a set of spare copper SFPs for use on UTP cables parallelling the fiber if something goes bad.
also bare in mind if you do this on more switches then spanning tree or it's new rstp versions comes into play. Basicly have redundant pathes in the network (which is a big no no in ehternet) and the spanning tree blocks them so no loop ocours and if a link goes down spanning tree will recalculate and enable a redundant link.
@@alexanderg9106: The copper SFPs are spares - only one SFP can be plugged in at a time anyway, and I have them so no other port configuration needs to be changed to swap between SFP media types. There is only one trunked port coming in to any of my peripheral switches.
@@alexanderg9106: And rather than getting fancy with redundant links and equipment, I just swap out failed parts (I have spare switches for everything I run) - It is a home environment after all. 😁
Randomly found this video, where I work (a WISP) we use SFP and SFP+
Cool to learn more about them
"Rare use case"? As a home lab user, I've got a DAC between my NAS and switch and budget server and switch, so both have a 10G connection to each other.
Literally every tech channel: You've never seen this network adapter
Uma falha na versão em português, creio que está sendo feita automaticamente: Quando se menciona o conector RJ-45, o apresentador diz "Rio de Janeiro 45", pois, coincidentemente RJ é a sigla do estado do Rio de Janeiro.
Wow... Thank you for the fact that you really get various sound tracks, this allows you to better understand you (since my knowledge of a foreign language is very poor), and listen to your videos with great interest!
