Abstract
An optical transceiver that reduces the EMI noise leaked therefrom is reduced is disclosed. The optical transceiver of the invention provides a metal housing, an optical subassembly, and an electronic circuit. The metal housing includes a first space that installs the electronic circuit and a second space that installs the optical subassembly. The first space and the second space are electrically shielded to each other, in addition that both spaces are shielded from the external. In the optical transceiver of the invention, even the second space provides the optical path to the optical connector, which becomes a definite leak path for the EMI noise, the leakage from the first space to the external through the optical path is prevented.
