Abstract
An optical transceiver module includes N light sources, N light detectors, a bidirectional fiber port, and an optical network having 2N−1 wavelength-selective elements. The number 2N represents the total number of transmit and receive channels in a bidirectional system in which transmit and receive signals corresponding to the transmit and receive channels. Each light source corresponds to one transmit channel and emits an optical transmit signal having a unique transmit wavelength. Each light detector corresponds to one receive channel and detects an optical receive signal having a unique receive wavelength. The optical network couples each light source to the bidirectional fiber port via a corresponding transmit path through the optical network. The optical network further couples each light detector to the bidirectional fiber port via a corresponding receive path through the optical network. Each transmit and receive path includes some of the wavelength-selective elements.
