Abstract
A module, system and method adjusts a tunable filter to have an adjustable frequency response based on one of an outbound optical signal on a transmit channel and an inbound optical signal on a receive channel. The tunable filter is in an optical path of the outbound optical signal and in an optical path of the inbound optical signal. The transmit and the receive channels are configured as part of a channel plan of a bidirectional (bi-di) dense wavelength division multiplexing (DWDM) system.
