Patent ID: 7634197

Claim:
An optical transceiver module, comprising: an optical transmitter containing a laser diode; a first sensor for sensing a predetermined parameter relating to operation of the laser diode, wherein the first sensor is a monitor photodiode, and wherein the predetermined parameter relates to laser power of the laser diode; at least one additional sensor for sensing at least one additional parameter that affects measurement of the predetermined parameter; and a processor capable of executing microcode, wherein the microcode, when executed, causes the optical transceiver to perform the following: by the first sensor, sensing data relating to the predetermined parameter; by the at least one additional sensor, sensing data relating to the at least one additional parameter; and according to a formulaic relationship relating the data of the predetermined parameter and the data of the at least one additional parameter, calculating a result relating to the predetermined parameter, wherein the formulaic relationship is configured to eliminate discrepancies relating to temperature and voltage fluctuations of the monitor photodiode.
