I have a 30m 10gb fibre run to the garage.. I thought everyone did this sort of thing :-P

Firstly, I'm not everyone, secondly, it depends on what’s in the garage, and thirdly, there are enough smart spenders out there who save money at the wrong end. That I have to tell you this as an IT professional? ;-)

- NET: FTTH & VDSL, OPNsense, 10G backbone, GWN APs
- SRV: 12 RU HA server cluster, 0.1 PB storage on premise
- IoT: thread, zigbee, tasmota, BidCoS, LoRa, WX suite, IR
- 3D: two 3D printers, 3D scanner, CNC router, laser cutter

@Mehrts Why did you unnecessarily limit the link bandwith by using only a simplex fibre? For a later server AND multi cameras, you can‘t have bandwith enough, especially when you have multiple camera streams from and a massive server backup job to the garage? In the worst case, your bandwidth is only a quarter of what a standard OM LC/LC duplex line provides to the switch (and has been more expensive because of the simplex SFP modules).

Hi @Tinkerisk, It is a duplex cable, I'm just not using the other core (the other end is tucked behind the plywood).

Not sure why you'd mention the limitation of speed, as that's typically determined by the transceiver of choice. Up to 100GbE is supported by SM LC BiDi transceivers with the QSFP form factor.

For this distance, the price between using multimode and singlemode fibre/transceivers was pretty much the same. The BiDi capability of SM transceivers was the reason why I went that way.

Anyway, the rest of my network hasn't even reached 10GbE status yet. And if/when the time comes for a speed boost to the shed, I'll just use different transceivers and switch etc.

That‘s ok, I wasn‘t aware of it since it looks like only one fibre to me. Then bandwidth isn‘t an issue in the future. Yes for that small distance, singe/multimode either works fine and BiDi is Duplex on the same fibre due to different wavelengths. Not the cheapest, but the most sophisticated solution for a garage. ;-)
