Patent ID: 8831433

Claim:
A multi-channel transceiver module comprising: a transceiver housing; a temperature controlled multi-channel transmitter optical subassembly (TOSA) located in the transceiver housing, the TOSA being configured to transmit a wavelength division multiplexed (WDM) optical signal on multiple channel wavelengths, the TOSA comprising: an array of lasers configured to generate laser light, wherein each of the lasers are associated with different respective optical channels; an arrayed waveguide grating (AWG) optically coupled to the array of lasers and configured to combine the laser light at different respective channel wavelengths; and a temperature control system configured to control temperature of both the array of lasers and the AWG with a same temperature control device; and a multi-channel receiver optical subassembly (ROSA) located in the transceiver housing, the ROSA being configured to receive a wavelength division multiplexed (WDM) optical signal on multiple channel wavelengths.
