Cooperative multi-point (CoMP) in a passive optical network (PON)

摘要

A method for error detection within a passive optical network (PON), the method comprising receiving a first upstream optical signal that is copied at an optical splitter, converting the first upstream optical signal to a first electrical signal, receiving a second electrical signal that is converted from a second upstream optical signal that is copied at the optical splitter, and determining a corrected transmitted data stream using at least the first electrical signal and the second electrical signal, wherein the first upstream optical signal and the second upstream optical signal are copies of an upstream optical signal generated from a plurality of optical network units (ONUs).

主权项

1. An apparatus for detecting errors within a passive optical network (PON), comprising:
a memory; a processor coupled to the memory, wherein the memory includes instructions that when executed by the processor cause the apparatus to perform the following:
obtain a first information stream from a first upstream optical signal;obtain a second information stream from a second upstream optical signal;generate a corrected information stream using at least the first information stream and the second information stream by comparing the first information stream to the second information stream in order to determine errors in each of the first and second information streams; andperform forward error correction (FEC) decoding on the corrected information stream, wherein the first upstream optical signal and the second upstream optical signal are received at an optical line terminal (OLT) and from an optical distribution network (ODN).
