Abstract:
1. An optical communications module comprising: a circuit board having a metal pattern thereon; a heat dissipation layer covering separate areas of the metal pattern, the heat dissipation layer comprising a layer of thermally-conductive material, a first area of the heat dissipation layer extending between opposed portions of a second area of the heat dissipation layer; at least a first optoelectronic component disposed on a first portion of the first area of the heat dissipation layer, wherein at least some heat that is generated by the first optoelectronic component flows into the first portion of the heat dissipation layer; and at least a first integrated circuit (IC) disposed on at least one of the opposed portions of the second area of the heat dissipation layer, wherein at least some heat that is generated by the first IC flows into the at least one of the opposed portions of the second area of the heat dissipation layer, and wherein the first and second areas of the heat dissipation layer are thermally decoupled from one another.
