Abstract:
1. A method of calibrating a monitor photodiode that measures an optical output power generated by an optoelectronic transceiver module that includes a burst mode laser diode, comprising: disabling a power control loop that controls an average optical output power generated by the laser diode during a laser burst; applying a series of logic zero signals to a data input of the transceiver module; measuring a logic zero level of an optical signal generated by the burst mode laser diode while applying the series of logic zero signals; adjusting a logic zero bias level applied to the laser diode until the measured logic zero level of the optical signal reaches a first predetermined value; and storing a first value of a current generated by the monitor photodiode in response to optical energy received from a back facet of the laser diode while the optical signal is maintained at the first predetermined value.
