Abstract:
1. An optical transceiver module, comprising: a housing attachable with an optical fiber; an optical multiplexer and demultiplexer disposed within the housing; at least one light emitting element; a plurality of light receiving elements; and a base on which the light emitting element and the light receiving elements are mounted, and which is fitted to the housing, wherein the optical multiplexer and demultiplexer includes a substrate, and a plurality of wavelength selection filters disposed on both surfaces of the substrate, is disposed substantially parallel to the base, and outputs a light, which has been input obiiquglv to a main surface thereof, at a position different according to a wavelength of the obliquely input light to the main surface, and wherein the housing has a recess, wherein the optical multiplexer and demultipiexer and the base are orthogonal to a wall surface of the recess. wherein the light emitting element emits a light obliquely to a surface of the base and a main surface of the optical multiplexer and demultiplexer, and wherein the light receiving elements receive a light obliquely to a surface of the base and a main surface of the optical multiplexer and demultiplexer.
