Patent ID: 8837934

Claim:
An arrangement for monitoring a plurality of operating parameters associated with an optical transceiver including both an optical transmitter and an optical receiver, the arrangement comprising a micro-controller unit for generating a reference signal output and receiving an input digital control signal associated with a selected one of the operating parameters of the optical transceiver, the micro-controller unit including a decision logic program module for controlling a value of the reference signal output and determining an assigned value of an operating parameter as equal to an reference signal output voltage when the input digital control signal changes state; and a comparator module responsive to the reference signal output from the micro-controller unit and also responsive to a plurality of analog monitoring signals, the comparator module for comparing the reference signal output to a selected one of the plurality of analog monitoring signals and for generating a state transition output digital signal when the value of the reference signal output voltage approximates the value of the selected analog monitoring signal, the state transition output digital signal applied as the digital control signal inputs to the micro-controller unit.
