Abstract
For an optical network link, a receiving node monitors optical performance and upon determination of lowered optical performance for an extended period of time, the node can signal a transmitting node to lower bit transfer rate from a nominal bit transfer rate. The receiving node has a transponder which has a digital electronic variable bandwidth filter to process the digitized signals at the lowered bit transfer rate to increase the SNR of the signals. Optical performance of the link is optimized although at the lowered bit transfer rate.
