Abstract
A method, transceiver, and system for monitoring performance of a fiber optic-based communication network and, in particular to determining contributing linear and nonlinear noise components, is disclosed. The method includes computing fast bit error rate of a received optical signal at a sampling time interval that is less than or equal to 100 microseconds (μsecs), generating, over a time period, a bit error rate distribution data associated with the computed fast bit error rate, applying statistical measurements to the bit error rate distribution data to extract statistical attribute data of the bit error rate distribution data, processing the extracted statistical attribute data to separately determine nonlinear noise components and linear noise components that contribute to total noise levels, and changing a launch power associated with an optical signal to be transmitted in accordance with separately determined nonlinear noise components and linear noise components.
