Fibre-Optic Curiosity Poll: people who deploy single-mode point-to-point fibre links (any distance beyond inside a datacenter), do you use two-strand optics, or single-strand with two colours? Please #boost!

I very much lean on Bi-Di optics since I figure there's half the amount of OSP cable to go wrong, and swapping failed optics is MUCH easier than splicing a bad strand in an inaccessible flooded underground vault that's on fire.

Let me know in the comments what you do, and why.

[Note top-of-rack/intra-rack and in-datacenter is NOT what I'm asking about that. That's the realm of MMF and DACs.]

Additionally I'm wondering about NNIs and medium-haul 100G+ links, since bidi there is LESS common, but is beginning to happen. LR4 -> LR2 <- LR1???

#Scientists have demonstrated #quantum #teleportation over the #Internet for the first time

It may not be teleportation like you see in the movies, but it's real. Scientists at Northwestern University have successfully demonstrated, for the first time, quantum teleportation via #fibre #optic cables carrying internet traffic.

#China bans export of key #minerals to #US as trade frictions escalate
China has banned exports to the #UnitedStates of items related to the minerals #gallium, #germanium and #antimony that have potential military applications, it said on Tuesday, a day after Washington's latest crackdown on China's chip sector.
Gallium and germanium are used in #semiconductors, while germanium is also used in infrared technology, #fibreoptic cables and #solar cells.

I am looking at adding networks between four buildings in a rural property. Runs are 30m, 60m, 80m and 180m.
(I have a soft spot for digging trenches, I love it in fact.) (I also hate wireless, I spend too much of my professional life with it. Wireless miasma will not seep into home life)

I'd hoped that I woulds type in "plastic optic fiber" and get back results selling me cheap, cheery and essentially guilt-free 100 Mbps networking gear. Alas, #POF seems to have been an evolutionary dead-end.

What happened?
Where did you buy your preterminated bury-able runs #fibreOptic switches from?

BAC 1-11-475AM The BAC 1-11 was a moderately successful twin-engine jetliner (similar in configuration to the MD-80, Fokker 100, etc). This example - preserved at #Brooklands #Museum, #Weybridge, #UK - was a demonstrator for the then experimental 'Fly By Light' #fibreoptic #controlsystem. #BAC #airliner #aviation #technology #commercialaviation #aviationphotography #photography
