Abstract: A telecommunications system and constituent integrated circuit that includes a post-amplifier assembly configured for communication with an optical receiver, a laser driver assembly configured for communication with the optical transmitter, and a controller assembly configured to control the post-amplifier and laser driver. The post-amplifier, the laser driver, and the controller assemblies are embodied on a single integrated circuit, thereby reducing manufacturing costs. Noise due to clock generation may be reduced by having the clock act on a transient basis, turning on when needed during the boot process, and turning off when not needed during normal operation.

Abstract: This disclosure concerns methods for calibrating an operating optoelectronic devices. In one example, a calibration method involves adjusting, at a first temperature, a control parameter until a device operating requirement is satisfied. The associated value of the control parameter is then recorded. This process of adjustment and recording is then repeated at one or more additional temperatures. During operation of the device, an associated temperature is sensed and the control parameter values associated with that temperature are used as a basis for generation of control signals that adjust performance of the device until a device operating requirement is satisfied.
