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?
