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.
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.
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.
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.
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.
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.
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.
"...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. 😁
Use it at home to run fiber setup from 1st floor to basement, as of now just a single converter in between to go from modem to Ethernet converter to converter to Ethernet and attached to router in basement for now with wifi turned off getting switch tomorrow to make it better in terms of that comes sfp too
I have a whole home network setup with a TrendNet 24-1GB and 4 SFP+ ports. I have one sfp port for my Pc at 2.5Gbps and 2 for my Synology DS1618+ duel 10Gbps (Aggregated) to equal 20Gbps. It works very well with the SFP+ and RJ45 adapters.
I have worked with networks for years. The issues he has with the Netgear handling 10gb to 1gb can be attributed to many things. Could simply be a firmware issue. If not, it maybe the hardware design. Meaning that it depends on the SOC, on board memory, chipset compatibility, or other issues. Net gear has always been popular in the retail market. They do make some corporate grade equipment. I have used net gear switches for small remote locations. I don't think they make the best enterprise type of equipment. That would have to go to Cisco or other enterprise level switches. Even with Cisco, I have seen some connectivity issues. Usually the firmware on the main switch and/or the firmware for add on hardware like and sfp. Most lower end switches are made cheap as possible. So they do not have the best SOC, RAM, cache memory, and other hardware configurations. So it is always best to analyze the situation and your need. Do research. Plan for any future growth, needs, and scalability. Then go from there. Always pay close attention to the specs of the equipment.
Why can't there be a setting in youtube to not switch to german audio automatically :( while i very much see the valueadd of your automated translations, i much prefer listening to the english version over the ai generated german
I literally got to know these from the LMG vids. For those who don't know, LMG Stands for Linus Media Group & it's the company headed by Linus Sebastian which has YT channels LTT(Linus Tech Tips), Techquickie, Short Circuit, etc.
Last month I also added 10G to my Synology and pc. I use mellanox x3 cards from AliExpress with a qnap qsw-m408-2c switch which has 4 10G ports and 8 1G ports, of which 2x 10G combo ports. Next switch is a qnap qsw-1108-8t to living room and router which is 2.5Gbit.
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.
If you have your NAS close to the switch, I suggest using those SPF+ DAC cables. Those only cost 20 - 30 euro and work just fine. Also if you ever try to connect two switches close to each other, please use such a DAC cable and don't use optics or Ethernet. A DAC cable is a lot more energy efficient and also running really short optical cables will in the end damage your optics as the received signal is too strong. There are attenuators available for it, but that's like putting sunglasses on fiber optic cable. Another disadvantage of 10G ethernet is that they are absolutely power hungry. That's why you hardly ever see 10G Ethernet switches with lots of Ethernet ports and if you do, the ports are often not close to each other (or per pair). If they are close to each other, the switch will have a fan. The nice thing about those SFP/SFP+ connectors is that they are remarkably robust and the locking mechanisms also make sure you have the cables/fibers unplugged when fiddling with them. And those DAC cables are just great for stacking switches or connecting servers in a rack to the switch. Really love them! Only downside is that they are not at all flexible. (at least not the ones I've seen) Another nice thing about QSFP+ is that you can also split them. So a 40G connection can be split into 4x 10G. Not sure how compatible this feature is between brands, but at least on the Dell ones I've seen, it worked very well.
yes, dac cables are more energy efficient because no major conversion needs to happen. the thick cables makes them perfect for holding switches like bags. jk.
I would be interested to see how many milliwatts different people might measure on their fiber connections. Apparently, in short distance not much power is required but, on some as much as 50mw can come out of the fiber. That would certainly hurt to look into. (I am in IT but, I used to work with UV lasers)
Thanks for getting right to the meat...in other words you first motivate by presenting the problem and use-case, then introduce the subject of this clip as a possible solution and all its variants....GREAT BIG THANK YOU!
If you are shopping fiber for your home you NEED to look on eBay. Fiber cable is so much cheaper than RJ45 and the fiber modules are dirt cheap secondhand on eBay. If you think running fiber is expensive you’re just not shopping correctly.
The option to have autotranslate dubs is great, but can you please make a video how to disable the title translations in general. It's really confusing if you search a topic in your language, seeing the title and than it's in english. Happens all the time. Btw, the last chapter description in the chapter-view makes totally no sense in german. 😂
I happen to know it all too well. Worked in storage field for ca. 7 years - SAN, NAS, Fibre, you name it, I did it. Funny thing is that I've never liked it all too much, lol. I just love UNIX and unix-like systems, so I usually land in a job that has tons of nix in it - before and currently - sysadmin and devops. Anyhow, SFPs tend to fail pretty often, so you better have a spare one somewhere near you.
Literally every tech channel: You've never seen this network adapter
Рік тому
i mean... ok, maybe somebody hasn't heard of SFP for some or other reason.... but if you're a net-sys-dev-ops .... and you haven't heard of SFP... just drop anything but dev in your CV. it was normal on any prosumer/commercial not to mention enterprise switches for above 2 decades. still liking the video though, but... it's not new, or not standard. you can get it on some home user routers regularly nowadays
Рік тому
and yeah, for the dropped frames... consider checking your MTU between your devices ... that's the most common problem with those type of dropouts
@ThioJoe feel free to give me a shout if you want to learn more on the in depths of networking. Can show a few things and maybe assist for some future content
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.
Those are common connectors for me. They are used for every installation for fiber optic internet in Canada and since I worked as phone support for those connections, I have become very familiar with them
@@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.
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.
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.
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.
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.
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.
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 hate the audio track feature. I subscribed to this channel because I understand English, I don't need a shitty translation. I want the original audio. I understand this can be useful to some people, but why can't I disable it ? On every video I click, I have to scroll through all the languages like an idiot just to find English and every time it's in a different place on the list. Why is the original audio not the first track on the list? Why are languages not sorted alphabeticaly ? I don't know. But at least I have the option to change the audio track I guess. Because what is even worse than the audio tracks is the translated title. I can't disable them and I can't choose the language I want. I have no way of knowing what the original title was and I'm stuck with that stupid translation which doesn't even mean anything half of the time.
This is valid criticism and I've just submitted some suggestions including these to UA-cam to let them know. They said they've heard the complaints and are exploring ways to fix them.
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.
OMG, this language conversion might be a nice new technology, but it's really... I mean... really not mature, Italian is really strange and mechanic, and takes out all the human feeling. There also some translation errors... awful... 😞
Same. If I change my youtube language to english, videos in my native language now have titles in english. If I change it to my native language, english videos are in my native language. Its annoying. UA-cam should fix it. Its good that thiojoe translates it though, useful for people not good at english
Hm do any of these suggestions help at all?: www.makeuseof.com/stop-youtube-translating-video-titles/ There might be a way to stop it from doing that based on UA-cam preferences. German is a common language I've seen people make this complaint with, so I might just avoid adding a German dub in the future, since I believe most Germans speak English anyway.
@@ThioJoe Unfortunately it's been a known problem for years. Even when listing all understood languages in the settings of a Google account, UA-cam still doesn't care and translates titles and descriptions to the UA-cam UI's language, even when the title or desc is in a language the user understands. Thankfully, since UA-cam removed the translations made by the community and since most UA-camrs don't care about translating their videos, it's been mostly a non problem for the last year or two (at least for me).
@@Yougi Its exactly that. I set German as ma main/native/preferred language, but also added English, but UA-cam doesn't care. It's even worse in the app, because for god knows reason the subtitles get automatically activated for every English video, if they have one not auto translated. Even after I disabled them in the app outright. And if I change to English as my display language in UA-cam it gets worse, for me at least, because now all German videos gets translated/get subtitles.
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
"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.
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.
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...

this^ not all SFP's have the power to blast fiber down a couple KM's run, some can only do a couple meters.

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
Use it at home to run fiber setup from 1st floor to basement, as of now just a single converter in between to go from modem to Ethernet converter to converter to Ethernet and attached to router in basement for now with wifi turned off getting switch tomorrow to make it better in terms of that comes sfp too
Was waiting for the next video to check out the audio tracks.
Good stuff. I use fiber SFP, SFP+ and DAC and some RJ45 transceivers for 10G. Still, I learned some stuff today. Thanks.
I worked at telco for 7 years, I'm very familiar with these😁
Both DACs and optical transceivers have some sort of PROM in them. Some brand of networking hardware care about what's flashed on them, some don't.
I have a whole home network setup with a TrendNet 24-1GB and 4 SFP+ ports. I have one sfp port for my Pc at 2.5Gbps and 2 for my Synology DS1618+ duel 10Gbps (Aggregated) to equal 20Gbps. It works very well with the SFP+ and RJ45 adapters.
I have worked with networks for years. The issues he has with the Netgear handling 10gb to 1gb can be attributed to many things. Could simply be a firmware issue. If not, it maybe the hardware design. Meaning that it depends on the SOC, on board memory, chipset compatibility, or other issues. Net gear has always been popular in the retail market. They do make some corporate grade equipment. I have used net gear switches for small remote locations. I don't think they make the best enterprise type of equipment. That would have to go to Cisco or other enterprise level switches. Even with Cisco, I have seen some connectivity issues. Usually the firmware on the main switch and/or the firmware for add on hardware like and sfp. Most lower end switches are made cheap as possible. So they do not have the best SOC, RAM, cache memory, and other hardware configurations. So it is always best to analyze the situation and your need. Do research. Plan for any future growth, needs, and scalability. Then go from there. Always pay close attention to the specs of the equipment.
Why can't there be a setting in youtube to not switch to german audio automatically :( while i very much see the valueadd of your automated translations, i much prefer listening to the english version over the ai generated german
I literally got to know these from the LMG vids.
For those who don't know, LMG Stands for Linus Media Group & it's the company headed by Linus Sebastian which has YT channels LTT(Linus Tech Tips), Techquickie, Short Circuit, etc.
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"
I use the SFP and SFP+ modules to connect my NAS and PC to the switch and my gateway/router to the ISP.
With old tech I just try not to hit my head against a brick wall😂
Last month I also added 10G to my Synology and pc. I use mellanox x3 cards from AliExpress with a qnap qsw-m408-2c switch which has 4 10G ports and 8 1G ports, of which 2x 10G combo ports. Next switch is a qnap qsw-1108-8t to living room and router which is 2.5Gbit.
Well I don't really use them but like you said now I know 😁
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.
I accidentally pulled one of these out of the back of my new AT&T fiber modem the other day, I wondered what it was! 😅 Lol, thanks for the info, Joe!
Note: they work much better when plugged in, hehe 😉
I am familiar with this connector from my ccna course watching this connector again after months
If you have your NAS close to the switch, I suggest using those SPF+ DAC cables.
Those only cost 20 - 30 euro and work just fine.
Also if you ever try to connect two switches close to each other, please use such a DAC cable and don't use optics or Ethernet.
A DAC cable is a lot more energy efficient and also running really short optical cables will in the end damage your optics as the received signal is too strong. There are attenuators available for it, but that's like putting sunglasses on fiber optic cable.
Another disadvantage of 10G ethernet is that they are absolutely power hungry.
That's why you hardly ever see 10G Ethernet switches with lots of Ethernet ports and if you do, the ports are often not close to each other (or per pair).
If they are close to each other, the switch will have a fan.
The nice thing about those SFP/SFP+ connectors is that they are remarkably robust and the locking mechanisms also make sure you have the cables/fibers unplugged when fiddling with them.
And those DAC cables are just great for stacking switches or connecting servers in a rack to the switch. Really love them!
Only downside is that they are not at all flexible. (at least not the ones I've seen)
Another nice thing about QSFP+ is that you can also split them. So a 40G connection can be split into 4x 10G. Not sure how compatible this feature is between brands, but at least on the Dell ones I've seen, it worked very well.
yes, dac cables are more energy efficient because no major conversion needs to happen. the thick cables makes them perfect for holding switches like bags. jk.
Is there some sort of adapter to go from J-45 to SP?
I was researching my laptop parts and this part showed up in some ads.
e621 servers be like
I would be interested to see how many milliwatts different people might measure on their fiber connections. Apparently, in short distance not much power is required but, on some as much as 50mw can come out of the fiber. That would certainly hurt to look into. (I am in IT but, I used to work with UV lasers)
In a telecom environment, you'd often use optical attenuators to pad down a strong signal.
Thanks for getting right to the meat...in other words you first motivate by presenting the problem and use-case, then introduce the subject of this clip as a possible solution and all its variants....GREAT BIG THANK YOU!
If you are shopping fiber for your home you NEED to look on eBay. Fiber cable is so much cheaper than RJ45 and the fiber modules are dirt cheap secondhand on eBay.
If you think running fiber is expensive you’re just not shopping correctly.
do they make the internet faster? if so, then I need one because i only have 10mbit/s download speed and 1mbit/s upload speed
What’s up Thio!
I use 4 SFP+ transceivers at home. They are connecting my Hyper-V cluster an Storage and the fourth one goes to my PC 👌🏻
man, why rj was translated to Rio de Janeiro? But thanks for the translation
The option to have autotranslate dubs is great, but can you please make a video how to disable the title translations in general. It's really confusing if you search a topic in your language, seeing the title and than it's in english. Happens all the time.
Btw, the last chapter description in the chapter-view makes totally no sense in german. 😂
I have seen it , used it , a lot
Translation messing up abbreviations (eg RJ45). Try to use plain english words for translation purposes (eg Network connector).
I happen to know it all too well. Worked in storage field for ca. 7 years - SAN, NAS, Fibre, you name it, I did it. Funny thing is that I've never liked it all too much, lol. I just love UNIX and unix-like systems, so I usually land in a job that has tons of nix in it - before and currently - sysadmin and devops.
Anyhow, SFPs tend to fail pretty often, so you better have a spare one somewhere near you.
He looked into the cable and he saw the entire internet. All at once.
I found them inside a server in a school
There's a saying when it comes to lasers and fiber optics: Don't look at the beam with the remaining eye!
1:08 portuguese IA translated RJ to Rio de Janeiro connector kkkkkkk
Literally every tech channel: You've never seen this network adapter
i mean... ok, maybe somebody hasn't heard of SFP for some or other reason.... but if you're a net-sys-dev-ops .... and you haven't heard of SFP... just drop anything but dev in your CV.
it was normal on any prosumer/commercial not to mention enterprise switches for above 2 decades.
still liking the video though, but... it's not new, or not standard. you can get it on some home user routers regularly nowadays
and yeah, for the dropped frames... consider checking your MTU between your devices ... that's the most common problem with those type of dropouts
hearing my language was shocking even tho i watched your video 3 weeks ago
I use them on my proxmox box 😄
Great work but Polish is almost unrecognizable when played fast but after all great tranzlating job

Please, STOP.
This tool translated RJ45 connector to "Rio de Janeiro 45".
In the consumer space, the Netgear R9000 has a single SFP+ port on it.
what about the almost forgotten windows 8 ?! ( never one video anywhere...

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 was so surprised to hear the audio in german all of a sudden lol
@@anonymouscommentator same

That's the wonders of automatic machine translation. You need a human to review everything.
RIO DE JANEIRO KKKKKKKK
Those are common connectors for me. They are used for every installation for fiber optic internet in Canada and since I worked as phone support for those connections, I have become very familiar with them
@@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.
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.
used 10g sfp+ is alot cheaper than rj45 10g imo. you can get much cheaper nics on ebay, and DAC cables arent very expensive
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.
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's are the older, much larger transceivers that were mostly replaced with the newer, much smaller SFP form-factor
@@giosal8822 yes, i think they were used to the old name and still called them gbic, but they were smaller like the spf.
@@CarloAnardu Yes, I agree that we also still called them GBIC's for several years after we started using SFP's, haha
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.
Well the internet is already a weird, downright strange place anyways.

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.
And do not forget 100Mbps devices like IP cameras, will also not communucate over 1Gbps SFP to RJ45 module
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.
If you don't have 100GbE in your house what are you doing with your 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 !!!
O áudio em português está trocando a sigla "RJ45" para "Rio de Janeiro 45"
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
omde encontro cabo rio de Janeiro 45 kkkkkkk
I hate the audio track feature. I subscribed to this channel because I understand English, I don't need a shitty translation. I want the original audio. I understand this can be useful to some people, but why can't I disable it ? On every video I click, I have to scroll through all the languages like an idiot just to find English and every time it's in a different place on the list. Why is the original audio not the first track on the list? Why are languages not sorted alphabeticaly ? I don't know. But at least I have the option to change the audio track I guess. Because what is even worse than the audio tracks is the translated title. I can't disable them and I can't choose the language I want. I have no way of knowing what the original title was and I'm stuck with that stupid translation which doesn't even mean anything half of the time.
This is valid criticism and I've just submitted some suggestions including these to UA-cam to let them know. They said they've heard the complaints and are exploring ways to fix them.
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.
OMG, this language conversion might be a nice new technology, but it's really... I mean... really not mature, Italian is really strange and mechanic, and takes out all the human feeling. There also some translation errors... awful... 😞
I wish I could disable subtitles, at least for English videos.
I hate to see, in my case, german title/description on an english video.
Same. If I change my youtube language to english, videos in my native language now have titles in english. If I change it to my native language, english videos are in my native language. Its annoying. UA-cam should fix it.
Its good that thiojoe translates it though, useful for people not good at english
Hm do any of these suggestions help at all?: www.makeuseof.com/stop-youtube-translating-video-titles/
There might be a way to stop it from doing that based on UA-cam preferences. German is a common language I've seen people make this complaint with, so I might just avoid adding a German dub in the future, since I believe most Germans speak English anyway.
@@ThioJoe Unfortunately it's been a known problem for years. Even when listing all understood languages in the settings of a Google account, UA-cam still doesn't care and translates titles and descriptions to the UA-cam UI's language, even when the title or desc is in a language the user understands. Thankfully, since UA-cam removed the translations made by the community and since most UA-camrs don't care about translating their videos, it's been mostly a non problem for the last year or two (at least for me).
@@Yougi Its exactly that. I set German as ma main/native/preferred language, but also added English, but UA-cam doesn't care.
It's even worse in the app, because for god knows reason the subtitles get automatically activated for every English video, if they have one not auto translated. Even after I disabled them in the app outright.
And if I change to English as my display language in UA-cam it gets worse, for me at least, because now all German videos gets translated/get subtitles.
Polish is soo bad, I dont want to "run on longer distances" xD
thank you for Polish dubbing, I feel like the translation isn't very good, but it's not bad aswell

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...
