Optical transceiver with mechanism to dissipate heat efficiently without affecting optical coupling condition

摘要

A heat dissipating mechanism from an optical assembly to housing without stressing the assembly against the housing is disclosed. The optical assembly has a box-shaped portion to install the optical device and the heat generating device. Among six walls of the box-shaped portion, rear and one side wall are provided for the signal transmission, and two side walls continuous to each other are provided for the heat conduction. The housing forms a hollow within which the optical assembly is set such that the two side walls of the optical assembly come in thermally contact with the bottom and one side wall of the hollow.
