Graded index 850nm/1300nm multimode, at least back in 1990 or so when I was a fiber tech, had basic specs that permitted 2km before repeating. I installed many projects with those distances before repeating. Actual equipment tolerances would have enabled the real distance to be much further. And that was with LED-based equipment, not even LASER.

I know distance isn't as much of an issue with fiber, but Marlon talked about ethernet *OR* fiber so I guess I was thinking ethernet over standard copper and was wondering if I was missing something simple/cheap to get/around over the 100m limit.
