Minimum cable length for SFP-OC3-IR1

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.

Re: Minimum cable length for SFP-OC3-IR1

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.
