Optical transceiver with optical receiver electrically isolated from housing and optical transmitter with enhanced heat dissipation to housing

摘要

An optical transceiver that copes with both the enhanced heat dissipation from heat generating components and the electrical isolation of components processing faint signals from other components generating EMI noises is disclosed. The optical transceiver provides, in addition to a bottom of a frame, a bottom cover made by material with higher thermal conductivity. The former components are directly mounted on the bottom cover through openings in the frame, while, other component to be electrically isolated from the chassis are mounted by putting an insulating support between them and the bottom cover.

主权项

1. An optical transceiver comprising:
an optical transmitter; an optical receiver; a metal frame installing the optical transmitter and the optical receiver thereon, the metal frame having a bottom surface and openings extending through the bottom surface, the openings corresponding to the optical transmitter and the optical receiver; and a bottom cover made of metal having thermal conductivity greater than thermal conductivity of the metal frame, the bottom cover overlaying the bottom surface of the metal frame; and wherein the optical transmitter is directly in contact with the bottom cover by passing through the opening for the optical transmitter, and the optical receiver is set in the opening for the optical receiver but electrically isolated from the bottom cover and the metal frame.
