Hi, Apologies for the off-topic post, but I figured there'd be a few fibre optic guru nerd types out there.
I need to connect some equipment (a router to a switch) via a dark fibre service. At each end, the service is presented as TX and RX on an optical circulator -- the fibre run itself is a single strand. My media converters are 100BASE-TX to 100BASE-FX, single-mode, 1310nm models, but the circulators are 1550nm models. I have been advised that my 1310nm optics should operate correctly, end-to-end, through the 1550nm circulators (albeit with 2-3dB extra loss -- still within our tolerances). Without knowing the underlying theory, or having the time to learn it, it's hard to approach the install with much confidence. Has anyone done this? Can anyone provide a concise explanation as to why it will or will not work? cheers, Dale PS: yes, there are other options, such as getting 1550nm media converters, or doing away with the circulators and getting single-strand media converters, or having the dark fibre provider swap in 1310nm circulators. _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
