Just patched a long fiber link, which would've absolutely _sucked_ to get CAT.7 cable through.
The steel-armored OS2 cable is cheap and super robust/easy to work with. The LC connectors are even smaller than the hole for CAT.7 would've been.

This is nice \o/

What I want to say is: Don't be afraid of fiber for DIY networking people, it's awesome and often muuuch better than copper cable!

I also didn't have to do any annoying LSA+ terminations or crimps and the link will do 10G+ easily :)

@manawyrm I've been curious about trying this once I actually make a permanent cable run to my tinker shop...what equipment did you use for either end of the cable? :)

@ann3nova

No-name china 1270nm/1330nm SMF BiDi SFP transceivers (12$ on Amazon)

One side is my regular big Ethernet switch, which already had some SFP ports.
The other side is a TP-Link SFP media converter (also 15$).

@manawyrm @ann3nova hey, because energy for a year can quickly become more expensive than the hardware: do you happen to have a wall-power measurement for the media converter? (just an order of magnitude, not something detailed. I want to know whether we're talking 4€/a in electricity, or 50€/a.

@funkylab @ann3nova
Mine's a TP-Link MC220 and it draws 1.3W from the wall (with an active 1000MBit/s link), including the SFP module.

So yeah, 4 Euro/Year sounds about right.

@manawyrm @ann3nova nice, that's super helpful!

@funkylab @ann3nova Seeing (and thinking about) this number made me realize why I like my solar setup soo much... 😆

@manawyrm @ann3nova yeah, used to be that that 1 W·a = 3€, now we're a bit above that, still a useful rule of thumb to estimate OPEX when "just" adding another fridge, heater, electric hamster or server to your zoo of devices.
