Adaptive Coded-Modulation for Intelligent Optical Transport Networks

摘要

A computer implemented method for dynamic data rate adjustment within a cascaded forward error correction FEC for optical communications includes subjecting data communicated over an optical network to a forward error correction in an encoding or decoding of the data, the encoding or decoding employing a codeword, re-encoding part of the codeword for generating a subsequent codeword where an actual code rate is tuned by adjusting a size of data encoded to provide re-encoded data, and dynamically changing the re-encoded data size to achieve cascaded rate adaptive FEC for communication of the data over the optical network.

1. A computer implemented method for dynamic data rate adjustment within a cascaded forward error correction FEC for optical communications, the method comprising the steps of:
i) subjecting data communicated over an optical network to a forward error correction in an encoding or decoding of the data, the encoding or decoding employing a codeword; ii) re-encoding part of the codeword for generating a subsequent codeword where an actual code rate is tuned by adjusting a size of data encoded to provide re-encoded data; and iii) dynamically changing the re-encoded data size to achieve cascaded rate adaptive FEC for communication of the data over the optical network.
