ABSTRACT:
According to embodiments of the present invention, an optical transponder module generates heat when operating and at least a copper heat wick and/or a copper block are disposed in the module body to perform passive transfer of heat from inside the optical transponder module to outside the optical transponder module. The heat wick may be soldered to thermal vias in the printed circuit board that is internal to the optical transponder module and positioned over the laser transmitter circuitry. The copper block may be positioned in a cutout in the optical transponder module body to acts as a heat spreader. Thermal grease, compounds, paste, interface material, etc., may be used to help the conduction of heat.
