Is there a minimum cable length for the SFP-OC3-IR1 fiber card in a PA-POS-1OC3 port adapter? We are installing a couple of OC-3 circuits and the telco side will be single-mode fiber. Our router will only be about 10 feet away from the telco port and I want to make sure that will work.
It looks like the IR has the following specs:
TX = -15 to -8 dBm
Loss budget is 0 to 12 dB.
You should be fine with that cable and no attenuation.
ALWAYS double-check with an optical power meter and scope/clean the fiber.
