Original Abstract Submitted
An optical network element detects an input optical signal at a preamplifier input and sets an output power level of the preamplifier at a predetermined Automatic Power Reduction (APR) power level. The optical network element starts an APR timer that expires after a first predetermined time period. While the APR timer is running, the optical network element measures an input power level of the input optical signal and calculates a span loss as a function of the difference between the predetermined APR power level and the measured input power level. After the expiration of the APR timer, the optical network element adjusts the output power level of the preamplifier output based on the calculated span loss.
