Patent ID: 7502564

Claim:
Circuitry for monitoring an optoelectronic device, comprising: memory configured for storing information related to the optoelectronic device; circuitry configured for: (i) receiving a plurality of analog signals from the optoelectronic device, the analog signals corresponding to current operating conditions of the optoelectronic device including a temperature of the optoelectronic device, transmitter output power, transmitter bias current, and received optical power, (ii) converting the received analog signals into digital values, and (iii) storing the digital values in memory mapped locations within the memory; and a two-wire serial interface for allowing a host device to read from and write to individual memory mapped locations within the memory in accordance with commands and individual addresses received from the host device, wherein the interface allows the host device to read the digital values corresponding to operating conditions of the optoelectronic device from host-specified individual memory mapped locations within the memory.
