Need suggestions on long runs (1,000'ish ft)

[58chev]

I don't think I'd use 62.5 multi mode though, 50 micron would make more sense.

Where I work, all our fiber is 50/125 with a couple of runs close to 1800' between buildings.

We do have some areas where fiber is in conduit out to a coupe of security guard houses. I am sure that these are no more than 12"-18" down, no where near below the frost line. Have been in operation without incident for well over 15 years now.
