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???

Future lunar missions may rely on a fibre-optic cables to assess vital sub-surface structures. Researchers at ETH Zurich are investigating whether lightweight optical fibres – like those used for internet communication on Earth – could be deployed on the Moon to detect seismic activity and reveal its interior structures.

There's a lot of people changing the phone lines around here. Is there a shortage of copper or something?
