Abstract:
1. An optical communications module comprising: a module housing comprising a front housing portion and a rear housing portion, wherein if the optical communications module is plugged into a receptacle formed in a front panel, the front housing portion is disposed in front of the front panel and the rear housing portion is disposed to the rear of the front panel; at least a first electrical subassembly (ESA) disposed in the module housing, the ESA including at least a first circuit board, at least a first integrated circuit (IC) mounted on the first circuit board, and at least a first array of laser diodes mounted on the first circuit board; a heat dissipation interface mechanically coupled to the rear housing portion and to said at least a first IC; at least a first heat dissipation device mechanically coupled to the rear housing portion and thermally coupled to the heat dissipation interface, wherein at least a portion of heat generated by said at least a first IC is thermally coupled into the first heat dissipation device via the thermal coupling between the first heat dissipation device and the heat dissipation interface; and at least a second heat dissipation device mechanically coupled to the front housing portion and thermally coupled to said at least a first array of laser diodes, wherein at least a portion of heat generated by the laser diodes is thermally coupled into the second heat dissipation device via the thermal coupling between the second heat dissipation device and the first array of laser diodes.
