What model gbic/sfp do I need for single mode yellow fiber going 1.5 miles? I’ve been looking around but can’t find any info. I have a 1gb gbic in an Etherwan EasyPoe Box going 1.5 miles using single mode yellow fiber into an extreme vsp-7400-48y. I get a link on the extreme side but not on the etherwan side. I was told to make sure I have the correct model gbic in the VSP.
I don't know the defaults in the VOSS OS but in EXOS, you may need to tweak settings for auto negotiation, speed, duplex etc. in that platform (X695 as it's called then).
