If two 1GB switches are next to each other in the rack and both have SFP ports what transceivers / cable is recommended?
You can use this BiDi SFP module (single mode, LC connector) whose speed is rated at 1.25Gbps, and connect two switches using a fiber optic patch cable. www.fastcabling.com/product/bidi-sfp-fiber-modules-2/
But if your switches have a Gigabit RJ45 uplink, you can connect them with Cat5e/Cat6 Ethernet cables directly.
very helpful, would be great if the meaning of each abbreviation were mentioned as well, like SFP, BiDi, QSFP+ etc
Thanks for your advice. will do in the next video.
Good job
Thanks for your comment. If you're interested, please subscribe to our channel. More videos are coming soon!
Thanks for the information. This is all fibre going out from the original router. Are there routers on the market that take direct fibre in connection. Probably just need a fibre to RJ45 adapter.
The Ubiquiti EdgeRouter 4 or MikroTik RB4011 have SFP ports that allow you to insert a fiber optic module directly.
Hello, thanks for the information provided on the video!
Just a quick question, is there any SFP transceivers for ONT or GPON fiber cables so it can it be used with the fastcabling media converter?
Context: In my country, fiber optic solutions provided by ISP are GPON based but their modem/router is very old hardware and i would like to use my own router
I thank you in advance for any help with that info :D
Unfortunately, SFP transceivers used in switches or media converters do not directly support GPON. GPON uses a specific protocol that requires a compatible GPON SFP module.
I learnd more here thani have from several weeks of Internet searches.
Just one question, please. Does the connection in your example carry data both ways? Or, is a second cable required? ( The terms may no longer be applicable, but is the connection simplex or duplex?)
The communication is bi-directional as we use a BiDi SFP module which can transmit data in both directions over a single fiber strand. The pre-terminated fiber cable is simplex, with 2 strands.
@@Fastcabling okay, let me see if I have this correct. Both directions are moving through a single strand, albeit on two different wavelengths I presume. The other strand is doing nothing. (?) Correct?
In other words, again assuming I understand, the connection could be made with a single strand cable, but you used the two strand cable for the SFP connector required by the BIDI SFP module.
The BiDi SFP module only uses one strand. The fiber cable consists of two strands so you can set up two connections.
@@Fastcabling thank you! I think I've got it now. I appreciate your responding to such an elementary question.
No big deal!
Was one sfp LC/ UPC simplex and the other one sfp APC/UPC simplex? Plugging in a UPC in on both?
FYI, this SFP module is compatible with LC/UPC simplex.
Confused, why use the rj45 converter to fiber at the router, vs just using an sfp+ to rj45 10G or 1G transceiver module at the switch side? I guess maybe depends on how easy it is to run the fiber vs cat6, shouldnt be a speed difference?
That's because the router doesn't have a fiber/SFP slot. The media converter is used to convert electrical siganls to optical signals, and vice versa.
@@FastcablingI assumed the RJ45 converter transceivers were bi directional so you could run cat 5 or cat 6 to the router
Yes, they can convert Ethernet signals from copper (RJ45) to fiber and from fiber back to copper (RJ45). You can run a Cat5/6 cable to the router and connect the media converters using the fiber optic cable.
I'm new to this fast networking world.
Why would I use an SFP+ transceiver for my 2.5G home network when I have the home cabled with Eth Cat 7?
In many home network scenarios, especially at 2.5G speeds, Cat 7 cabling will serve well and is a straightforward solution. While your current needs might be met with 2.5G, SFP+ supports up to 10Gbps. For example, connecting NAS devices, servers, or uplinks between switches might benefit from the higher throughput capabilities of 10G. The range of PoE/Ethernet is limited to 100 meters, while SFP+ modules with fiber optics can be used to extend the network over greater distances without signal degradation.
@@Fastcabling thank you for the detailed answer. Since it will be less than 100m, I think I will opt for cat 7. Thanks
Can we use it wirelessly ❓
No, it's used with fiber optic cables
just wanted to say you are very beautiful. Thanks for this.
