Some idiot jumpered runs that existed between 3 different buildings. That person did not know about the 550m limit that
we also follow.

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 a run of approximately 1670 meters.
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
you purchase dark from a provider? Is it inside of a building?
