Signal reflection mitigation in fiber-optic networks. Signal reflections are
mitigated using near-end echo cancellation, threshold adjustment and/or error correction
code. Signal reflections in a receive signal that are caused by near-end connectors
may be mitigated using an echo cancellation signal. Signal reflections caused by
other discontinuities on a fiber-optic network may be mitigated by using error
correction code. Also, an average value of a reflected signal maybe detected and
used to set an adjusted threshold value to interpret logical values of an electronic
or optical signal.
