Or they just have super fast tx/rx switching.

I'd be very impressed there's a lot of cable in these small things but I
suppose that is possible and it automatically reduces the length.

People say you need a launch cable but our cheap china OTDRs have no issues
seeing the connector at the end of the patch cable and stuff beyond. I bought
a big launch cable back in the day and never use it anymore.
Might be different with AE?

Only minimum length I know of is the OTDR dead zone. If that is a problem
you purposely lengthen the cable with a launch cable.

Reddit is wrong. Gasp.
Connectors are loss, there is more loss in either one of the connectors
than there is the single mode glass.
Between a switch/router in a rack what I see all the time is long (like
5/10/15 feet) cables and then put the slack in a loop along the posts.

Patchbox makes some great products, their fiber system is pretty slick
but expensive.
Cable length is irrelevant it's optical budget / Rx signal strength.
Normally on 2-20k LR optics you are ok with any length cable, 40km+ needs a pad
on short spans. (Attenuator)

I have been using 1 meter cables and they are almost always too long,
I’m talking about going between routers and switches in a rack, stuff like
that. I see that FS sells 0.5 meter cables, but I saw somewhere like maybe on
Reddit someone claiming there was a minimum length. Given SM fiber and LR
optics, I don’t see how 0.5 or 1.0 meter would be different they are both
essentially zero length.
Probably there’s some kind of cable tray or cable management solution I
could be using but I’ve never liked such things.
