ABSTRACT:
An optical transceiver device having digital and programmable control over transceiver components is disclosed. The optical transceiver module comprises a controller and an integrated post-amplifier/laser driver (“PA/LD”), which are included on a printed circuit board disposed in the module. Transmitting and receiving optical sub-assemblies for transceiving optical signals are also disposed in the module. A digital signal interface interconnects the controller with the integrated PA/LD. A microprocessor is interposed between the controller and the PA/LD and is connected to both components via the digital signal interface. Digital control signals produced by the controller are transmitted via the digital signal interface to the integrated PA/LD where they are converted to analog signals for use by a plurality of control amplifiers. Conversely, analog feedback signals produced by the control amplifiers are converted to digital signals and transmitted to the controller. The microprocessor can intercept, analyze, and modify the digital control and feedback signals for optimum use by the controller or integrated PA/LD.
