Multi-fiber interface automatic power reduction systems and methods

Abstract:

An optical module includes a plurality of ports configured to connect to a multi-fiber cable that includes transmit fibers and receive fibers therein for the plurality of ports; a detector for each of the plurality of ports configured to detect loss of signal at a port level; and a processor configured to perform automatic power reduction only for affected ports of the multi-fiber cable that have a detected loss of signal. The multi-fiber cable can be an MPO cable.
