ABSTRACT:
An optical receiver unit has an optical receiver module which includes an opto-electric converter housed in a metal container, a printed-circuit board having power, signal and ground terminals connected to the opto-electric converter, a casing body which includes a board receptacle and a module receptacle, respectively for accommodating the printed-circuit board and the optical receiver module, and a cover for covering the casing body. The casing body and the cover are both molded out of synthetic resin and have respective, first and second metallized internal surfaces. The cover covers the casing body so that the second metallized internal surface of the cover contacts the first metallized internal surface of the casing body. The ground line is connected to the metal container of the optical receiver module.
