US 2016/0080087 A1 · Inter-Channel Interference Management for Optical Super-Channels

Abstract

The transmission of data from a transmitter to a receiver over an optical super-channel including a set of sub-channels of different frequencies includes partitioning the data into a set of data streams including one data stream for each sub-channel and partitioning each data stream into a set of sub-streams. Each sub-stream of each data stream is encoded with different forward error correction (FEC) codes to produce a set of encoded sub-streams for each data stream, and the set of encoded sub-streams of each data stream are superimposed with different powers to produce a set of encoded data streams. The set of encoded data streams is multiplexed to produce an optical signal transmitted over the set of sub-channels of the optical super-channel.

Dependent claims

A method for transmission of data from a transmitter to a receiver over an optical super-channel including a set of sub-channels of different frequencies, comprising:

partitioning the data into a set of data streams including one data stream for each sub-channel;
partitioning each data stream into a set of sub-streams;
encoding each sub-stream of each data stream with a corresponding forward error correction (FEC) code to produce a set of encoded sub-streams for each data stream, wherein at least two encoded sub-streams in the set of encoded sub-streams are encoded with different FEC codes;
superimposing the set of encoded sub-streams of each data stream to produce a set of encoded data streams, wherein at least two encoded sub-streams in the set of encoded sub-streams are superimposed with different powers;
multiplexing the set of encoded data streams to produce an optical signal;
and
transmitting the optical signal over the set of sub-channels of the optical super-channel.

A system for transmission of data over an optical super-channel including a set of sub-channels of different wavelengths, comprising:

a set of sub-channel receivers for receiving a set of received data streams including one received data stream for each sub-channel receiver, wherein the received data stream includes at least portions of encoded sub-streams transmitted over different sub-channels of the optical super-channel, wherein a sub-channel receiver includes multiple decoders for decoding, jointly or successively, each encoded sub-stream of the received data stream to produce a set of decoded sub-streams;
