US Patent 7720387 Microcode-driven calculation of temperature-dependent operational parameters in an optical transmitter/receiver

An optical transceiver (or transmitter or receiver) that uses microcode that represents a formulaic relation between temperature and an appropriate value for an operational parameter given the temperature. The microcode is further structured such that when loaded into system memory and executed by the optical transceiver, the optical transceiver accesses the temperature as measured by a temperature sensor, calculates an appropriate value for the operational parameter given the accessed temperature using the formulaic relation, and adjusts the operational parameter according to the calculation. This allows the optical transceiver to adjust temperature-dependent operational parameters using less memory than required to perform a table-based representation of temperature versus the operational parameter.
