ABSTRACT:
A fiber optic module is provided that effectively reduces a returned light and is manufactured by a low time and cost consuming process and electronic equipment. The fiber optic transceiver module includes a block that includes an optical waveguide and a guide that is provided to one end of the optical waveguide and is a concave portion into which an optical fiber is inserted, and a micro tile-like element that includes a light emitting element or a light receiving element is attached to the block. A light emitting part of the light emitting element or a light receiving part of the light receiving element is disposed so as to face the other end of the optical waveguide. The optical waveguide includes a branch having a blind end.
