Heat dissipation type single/double-fiber pluggable optical module and assembling method thereof

Abstract

The invention relates to a heat dissipation type single / double-fiber pluggable optical module and an assembling method thereof. The optical module comprises a shell cover, a module circuit board, a base and an outer clamping fastener; the side edge of the module circuit board is clamped and fixed between the shell cover and the base to form two heat convection channels above and below the module circuit board, a heat conduction boss in the shell cover and the outer clamping fastener with a specific structure are utilized, the heat conduction boss is thermally coupled with a chip heating body,and the outer clamping fastener is attached to the shell cover in a heat conduction mode, and is buckled with the base in a heat conduction mode. A heat conduction path from the heat conduction boss to the base through the outer clamping fastener is established, the heat conduction path is an annular 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 data transmission of high-speed communication.
