Abstract
A bi-directional optical communication device comprising a reduced number of components for speedier and less costly manufacture includes a plate and a wavelength-division multiplexer disposed on the plate. An optical-signal transmitter disposed on the board emits first beam to the wavelength-division multiplexer and an optical-signal receiver disposed on the board detects the second beam emitted by the wavelength-division multiplexer. An optical receptacle is disposed on the plate for actual connection to an optical fiber. The optical fiber emits the second beam to the wavelength-division multiplexer, and the multiplexer emits the first beam to the optical fiber.
