Abstract:
This disclosure provides systems, methods, and apparatus for mitigating the effects of interference signals on optical signals received at a direct-detection optical receivers. The optical receivers are capable of attenuating interference noise signals resulting from the interference between a transmitted optical signal transmitted from a transmitter to the optical receiver and one or more additional signals received at the optical receiver. The interference can be due to multi-path interference or due to in-band interference. The receivers include a tunable filter for filtering the received optical signal to remove the interference. A frequency offset module processes the received optical signal to determine a frequency offset indicative of the difference between the carrier frequencies of a modulated optical signal and an interference optical signal. The offset frequency and a bandwidth determined by the frequency offset module can be used to adjust the tunable filter to remove the interference signal from the received signal.

Claim (Index 9):
The optical transmitter of  claim 1 , wherein the optical transmitter is a first optical transmitter, and the noise optical signal constitutes a reflection of a second optical signal transmitted by a second optical transmitter different from the first optical transmitter, the reflection occurring over a bi-directional optical link over which both the second optical signal and the modulated optical signal are transmitted.
