Abstract:
An optical network component and method are herein described. The system and method include determining a first power of an optical modulator using a first photodetector and a second power of the transmitter using a second photodetector, determining a contrast ratio based on the first power and the second power, and determining a modulation loss based on the contrast ratio.
