Patent ID: 7200337

Claim:
An optoelectronic transceiver comprising: an optoelectronic transmitter; an optoelectronic receiver; a laser driver electrically coupled to the optoelectronic transmitter; a post amplifier electrically coupled to the optoelectronic receiver; a first controller integrated circuit (IC) electrically coupled to the laser driver, wherein the first controller IC is configured to supply a direct current (DC) bias current control signal to the laser driver causing the laser driver to supply DC bias current having a predetermined level determined by the DC bias current control signal to the optoelectronic transmitter, and wherein the first controller IC is configured to access a first memory configured to store digital diagnostic data corresponding to operating conditions of the optoelectronic transceiver; and a second controller IC electrically coupled to the laser driver to supply an alternating current (AC) control signal to the laser driver causing the laser driver to supply modulation current having a modulation level determined by the AC current control signal to the optoelectronic transmitter, and wherein the second controller IC is configured to access a second memory configured to store digital diagnostic data corresponding to operating conditions of the optoelectronic transceiver.
