How did you end up with a MM run this long? SX optics are only rated at
500 meters at best. Even with mode conditioning jumpers more the 1km is a
risk. I'm glad it held up during testing though. Just out of curiosity
did
Some idiot jumpered runs that existed between 3 different buildings. That
person did not know about the 550m limit that we also follow.

I stand corrected, but I haven't dealt much with 100BASE-FX. I was just
talking in terms of 1G/10G.

Thanks to all who responded to my clumsy first question (both on
matters of etiquette and technology). The group I work with (we are a
small project acting as a last mile provider) was in the midst of
deploying this solution when I posed the question. We put the single
mode Juniper SFPs (LX) on to

As a suggestion, could you please in the future not use a subject such as
"Re: NANOG Digest, Vol 47, Issue 56" for posts. It is MUCH better to
use a topical subject line
