If two 1GB switches are next to each other in the rack and both have SFP ports what transceivers / cable is recommended?

[@Fastcabling]

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.

[@iulseyer]

very helpful, would be great if the meaning of each abbreviation were mentioned as well, like SFP, BiDi, QSFP+ etc

[@Fastcabling]

Thanks for your advice. will do in the next video.

[@peterbignell9482]

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.

[@Fastcabling]

The Ubiquiti EdgeRouter 4 or MikroTik RB4011 have SFP ports that allow you to insert a fiber optic module directly.

[@fermoralespy]

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

[@Fastcabling]

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.

[@daveriggs2411]

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?)

[@Fastcabling]

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.

[@daveriggs2411]

@@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.

[@Fastcabling]

The BiDi SFP module only uses one strand. The fiber cable consists of two strands so you can set up two connections.

[@daveriggs2411]

@@Fastcabling thank you! I think I've got it now. I appreciate your responding to such an elementary question.

[@Fastcabling]

No big deal!

[@sagesmith1969]

Was one sfp LC/ UPC simplex and the other one sfp APC/UPC simplex? Plugging in a UPC in on both?

[@Fastcabling]

FYI, this SFP module is compatible with LC/UPC simplex.

[@markm75]

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?

[@Fastcabling]

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.

[@markm75]

​@@FastcablingI assumed the RJ45 converter transceivers were bi directional so you could run cat 5 or cat 6 to the router

[@Fastcabling]

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.

[@barygol]

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?

[@Fastcabling]

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.

[@barygol]

@@Fastcabling thank you for the detailed answer. Since it will be less than 100m, I think I will opt for cat 7. Thanks

[@kapilsinghyadav5836]

Can we use it wirelessly ❓

[@Fastcabling]

No, it's used with fiber optic cables

[@Photoshopuzr]

just wanted to say you are very beautiful. Thanks for this.
