Abstract:
1. An optical transceiver module comprising: a module casing, the module casing having at least inner and outer surfaces and a first end having an opening formed therein; a receptacle secured within the opening formed in the first end, the receptacle being configured to receive at least a first optical connector having an end of at least a first optical fiber secured therein; an optical subassembly (OSA) disposed within the module casing, the OSA including at least a light source for producing light and an optics system for coupling the light produced by the light source between the end of the optical fiber and the light source; and a heat sink structure mechanically and thermally coupled to the OSA, at least a portion of the heat sink structure being in contact with a portion of the light source to allow heat produced by the light source to pass into the heat sink structure, at least one surface of the heat sink structure being in contact with the inner surface of the module casing to allow heat to pass from the heat sink structure into the module casing, and wherein at least one of the heat sink structure and the module casing is deformable in a predetermined manner such that when the heat sink structure or the module casing is deformed in said predetermined manner, a size of surface area on said at least one surface of the heat sink structure and a size of surface area on at least one surface of the module casing that are in contact with each other increase, and wherein the increase in the sizes of surface areas that are in contact with each other decreases thermal resistance along a thermal pathway from the light source to the module casing.
