BOX-TYPE PACKAGED OPTICAL TRANSCEIVER

A box-type packaged optical transceiver with multiplexing capabilities includes a box-shaped housing, a cover plate, an optical receiving module, an optical emitting module, a prism module, and an optical fiber connector. The housing has a through hole and is hermetically sealed by the cover plate. The optical receiving module, the optical emitting module and the prism module are disposed in the internal space. A first incoming optical signal is transmitted to the optical receiving module through the optical fiber connector, the through hole, and the prism module, and the optical emitting module emits an outgoing second optical signal through the prism module, the through hole, and the optical fiber connector.
