THERMAL MANAGEMENT OF PLUGGABLE OPTICAL TRANSCEIVER

Abstract:

Systems and devices for providing heat relief to an optical transceiver device are disclosed. The optical transceiver device includes a heat transfer structure that includes a heat slug connected to a high heat generating circuit in the optical transceiver device. The heat slug has a structure that allows heat to flow anisotropically from one surface of the heat slug that contacts the heat generating circuit to a second surface of the heat slug that is thermally coupled to a heat transfer device such as a heat sink. The perimeter of the heat slug is enclosed by an insulation frame. The insulation frame is configured to thermally isolate the heat slug by reducing heat transfer from the heat slug to other components of the optical transceiver device.
