METHOD AND SYSTEM FOR CONTROL LOOP RESPONSE TIME OPTIMIZATION

摘要

A method and system for optimizing a response time of a monitoring loop with forward error correction. Characteristics of a fiber optic communications channel are adjusted based on the number of errors corrected in the FEC decoder. An adaptive BER is calculated much faster by using a signal from an FEC decoder, than by comparing input and output transmission. Thereby, the lag time in adjusting the transmission characteristics of the fiber optic channel is minimized and the overall performance of the system is improved.
