Abstract:
In an example, a communication module includes an optical transmitter, an optical receiver, and a periodical filter. The optical transmitter is configured to emit an outbound optical signal. The optical receiver is configured to receive an inbound optical signal. A first frequency of the outbound optical signal is offset from a second frequency of the inbound optical signal by an amount less than a channel spacing of a multiplexer/demultiplexer implemented in an optical communication system that includes the communication module. The periodical filter is positioned in optical paths of both the outbound optical signal and the inbound optical signal and has a transmission spectrum with periodic transmission peaks and troughs. The first frequency of the outbound optical signal may be aligned to one of the transmission peaks and the second frequency of the inbound optical signal may be aligned to one of the transmission troughs, or vice versa.

Claim (Index 12):
A system comprising:\n a local multiplexer/demultiplexer that includes a fiber-side port and a plurality of module-side ports, wherein the fiber-side port is configured to be communicatively coupled to one end of an optical fiber having a remote multiplexer/demultiplexer at an other end of the optical fiber; a plurality of local bidirectional communication modules coupled to the plurality of module-side ports of the local multiplexer/demultiplexer, each of the plurality of local bidirectional communication modules configured to:\n transmit a corresponding outbound optical signal on a corresponding channel within a corresponding transmission peak of a transmission spectrum of the local multiplexer/demultiplexer and through a module-side port of the local multiplexer/demultiplexer; and \n receive a corresponding inbound optical signal on a corresponding channel within the same corresponding transmission peak of the transmission spectrum as the corresponding outbound optical signal and through the same module-side port of the local multiplexer/demultiplexer as the corresponding outbound optical signal; \n wherein a first frequency of the outbound optical signal is offset from a second frequency of the inbound optical signal by an amount less than a channel spacing of the local multiplexer/demultiplexer.
