Abstract
The optical-transceiver module includes an optical transmitter and an optical receiver. The optical transceiver module also includes an internal serial bus and a plurality of addressable components electrically coupled to the internal serial bus. Each of the addressable components included a serial interface for communicating with the internal serial bus, and a memory. Each addressable component also includes a unique address or chip select logic coupled to a controller via a chip select line. This allows data to be addressed to specific addressable components. The addressable components may include a laser driver, a laser bias controller, a power controller, a pre-amplifier, a post-amplifier, a laser wavelength controller, a main controller, a electrothermal cooler, an analog-to-digital converter, a digital-to analog converter, an APD bias controller, or any combination of the aforementioned components.
