The present disclosure is generally directed to an optical transceiver housing for use in an optical transceiver module with at least one vapor chamber integrated into the transceiver housing. In more detail, the transceiver housing includes at least first and second housing portions on opposite sides and forming a compartment defined by one or more inner surfaces therein. The vapor chamber includes a heat input side and a heat output side on opposite sides of the vapor chamber. An outer wall of at least one of the housing portions may be defined at least in part by the heat output side of the vapor chamber such that the heat output side is exposed to outside of the transceiver housing for transferring heat from inside to outside the optical transceiver module.
