Heat dissipation type single/double-fiber pluggable optical module, and assembling method and outer clamping fastener thereof

Abstract

The invention relates to a heat dissipation type single / double-fiber pluggable optical module, and an assembling method and outer clamping fastener thereof. The optical module comprises a shell cover,a module circuit board, a base and the outer clamping fastener. The side edge of the module circuit board is clamped and fixed between the shell cover and the base so as to form two heat convection channels over and under the module circuit board respectively; a heat conduction boss in the shell cover and the outer clamping fastener with a specific structure are utilized; the heat conduction bossis thermally coupled with a chip heating body, the outer clamping fastener is attached to the shell cover in a heat conduction manner, the base is buckled in a heat conduction manner, a heat conduction path from the heat conduction boss to the base through the outer clamping fastener is established and is a bad path surrounding the two heat convection channels, the air cooling type heat dissipation efficiency of a single / double-fiber pluggable optical module product is improved, and the optical module is suitable for high-speed communication data transmission.

Description

technical field [0001] The invention relates to the technical field of single / dual-fiber pluggable optical modules, in particular to a heat-dissipating single / dual-fiber pluggable optical module, an assembly method thereof, and an outer clip fastener. Background technique [0002] Single / dual-fiber pluggable optical modules are small pluggable transceiver devices containing active chips and optical receiver transmitters, used in high-speed telecommunications and data communications, in order to match 4G, 5G, 6G or more advanced wireless communication protocols The amount of data that needs to be transmitted within a limited time is also increasing. With the increase of transmission rate, such as 622Mb / s, 2.5Gb / s, 5Gb / s, or even 10G / s or higher, the heat generated by the internal chip is getting higher and higher. There are many, and the damage to the optical communication performance or / and the assembly structure is also increasing, such as communication signal distortion, c...
