Abstract
An optical transceiver module having a digital control interface is disclosed. The optical transceiver module comprises a controller and integrated post-amplifier/laser driver, which are included on a printed circuit board disposed in the module. Transmitting and receiving optical sub-assemblies are also disposed in the module. A digital signal interface interconnects the controller with the integrated post-amplifier/laser driver. Digital control signals produced by the controller are transmitted via the digital signal interface to the integrated post-amplifier/laser driver. After receipt by the integrated post-amplifier/laser driver, the digital control signals are converted to analog control signals and forwarded to control amplifiers that use the control signals to vary a plurality of operating parameters of the transceiver module. The digital signal interface can also be employed to provide feedback to the controller relating to the operation of the control devices.
