Optical module metal guide rail

An optical module metal guide rail comprises an elastic structural member (1), arranged on an inner wall of a housing heat absorbent surface (2) and used for contacting with an optical module for heat conduction. According to the optical module metal guide rail structure, the problems are solved that air gaps exist between a metal guide rail and the optical module, heat of the optical module is hard to smoothly conduct to the metal guide rail and there is a bottleneck to heat dissipation, thereby reducing conduction heat resistance between a guide rail housing and the optical module, improving the heat dissipation capacity of the metal guide rail and providing a better heat dissipation condition for the optical module.
