Title: ADAPTIVE FORWARD ERROR CORRECTION (FEC) IN PASSIVE OPTICAL NETWORKS (PONS)
Abstract:
Methods and apparatus are provided for use in a network such as an optical passive network (PON), and include a first decoder configured to decode an encoded data signal using a first code to generate a decoded signal. When the encoded data signal comprises unknown information that was not successfully decoded by the first decoder and would otherwise be ignored, the unknown information is included in the decoded signal. A second decoder can optionally be configured to decode the decoded signal using a stronger code than the first code.
