Abstract:
1. An optical transceiver, comprising: a transmitting side photoelectric converter configured to convert an electric signal into an optical signal; a transmitting side circuit board configured to mount the transmitting side photoelectric converter; a receiving side photoelectric converter configured to convert an optical signal into an electric signal; a receiving side circuit board configured to mount the receiving side photoelectric converter, a surface of the transmitting side circuit board mounting the transmitting side photoelectric converter being arranged to face a surface of the receiving side circuit board mounting the receiving side photoelectric converter; a lens block disposed between the transmitting side circuit board and the receiving side circuit board, the lens block having first and second side surfaces optically connected to a transmitting side optical fiber and a receiving side optical fiber respectively, the lens block being configured to input an optical signal outputted from the transmitting side photoelectric converter into the transmitting side optical fiber and to input an optical signal outputted from the receiving side optical fiber into the receiving side photoelectric converter; and a frame body configured to hold the lens block such that the lens block aligns with the transmitting side photoelectric converter and the receiving side photoelectric converter, the frame body being further configured to fix the transmitting side circuit board and the receiving side circuit board at a predetermined distance from each other, wherein the frame body covers third and fourth side surfaces of the lens block and does not cover the first and second side surfaces of the lens block, wherein the third and fourth side surfaces of the lens block are fixed to the frame body by an adhesive, wherein the frame body surrounds the transmitting side photoelectric converter and the receiving side photoelectric converter.
