ABSTRACT:
A method and an apparatus are provided for use in a parallel optical transmitter or transceiver to compensate for variations in optical crosstalk in an optical output power monitoring system that are caused by lasers being enabled and/or disabled. In particular, the method and apparatus cause adjustments to be made to the reference value of each optical channel based on determinations of whether one or more lasers of the other optical channels have been disabled or enabled. By making these adjustments, the average optical output power level of each laser of each channel can be maintained at a desired or required level even if one or more of the lasers of one or more of the other channels is enabled or disabled.
