Abstract
A multiband wavelength multiplexed optical device for bidirectional communication over one light path. The device may use dichroic filters or reflectors, or other mechanisms for wavelength or bandwidth separation or discrimination of sent or received light signals. It may have a multitude of light sources and detectors for sending and receiving light signals such as those for optical-based communications, controls and so forth. For instance, the optical device may be utilized in transceiver systems.
