Patent ID: 7625138

Claim:
An optical waveguide holding member to be mounted on a printed circuit board of an optical transceiver that receives an optical signal from an external device and converts the received optical signal into an electric signal and transmits another optical signal to the external device by converting another electric signal into the other optical signal, which optical waveguide holding member holds an optical waveguide between external optical fibers and photoelectric conversion elements formed in or mounted on the printed circuit board, comprising: a pair of flanges which is used to mount the optical waveguide holding member on the printed circuit board; a first connecting section which optically connects first ends of the optical waveguide to corresponding light receiving and emitting sections of the photoelectric conversion elements; and a second connecting section which optically connects second ends of the optical waveguide to the corresponding external optical fibers; wherein optical centers of the first connecting section and fixed centers of the flanges are arrayed on a same straight line; the photoelectric conversion elements are disposed in two blocks so that one of the blocks is used for receiving the optical signal and the other block is used for emitting the optical signal, and each of the blocks has plural photoelectric conversion elements for forming plural channels for the optical signals; the flanges are symmetrically disposed on corresponding side walls of the optical waveguide holding member viewed from the upper side of the optical waveguide holding member; and the fixed centers of the flanges and optical centers of the light receiving and emitting sections of the photoelectric conversion elements of the two blocks are arrayed on the same straight line at the first connecting section.
