PROBLEM TO BE SOLVED: To obtain an inexpensive optical transmitter-receiver in which radiation noise from an optical transmission section is less likely to be transmitted to an optical reception section, and reception sensitivity characteristics are not degraded.SOLUTION: In an optical transmitter-receiver consisting of an optical module and an electronic circuit board, the optical module includes an optical transmission section for converting an electric signal into an optical signal, an optical reception section for converting an optical signal into an electric signal, a housing for optically integrating the optical transmission section and optical reception section, and a light guide component being connected optically with a subscriber side optical line terminal (ONU) or a station office side optical line terminal (OLT). An electronic circuit board to which an optical module is fixed is secured to a case, the optical module and the electronic circuit board are connected using a flexible board mounting a radio wave absorber, and the radio wave absorber is held between the optical transmission section and optical reception section. |
