    摘要： Optical network devices and method for optical network communications in discrete multi-tone (DMT) are provided. A serial information signal is converted to groups of bits and loaded to parallel processing branches based on bit rates of the parallel processing branches. Each branch is configured to encode the associated group of data bits on the associated tone. A first bit rate and modulation and power allocation to a first branch of the branches may be different from a second bit rate and modulation and power allocation to a second branch of the branches. To recover the incoming data, the encoded signal may be parallel-processed using branches with different demodulation formats and provide the serial data stream.

    摘要： A method of optical communication comprising encoding four modulated symbols to generate four encoded symbols in two orthogonal polarizations and transmitting the four encoded symbols in two successive time slots. An optical communication apparatus comprising a processor configured to receive two sequences of digital symbols in a plurality of time slots, wherein the two sequences correspond to two components of two orthogonal polarizations, wherein one digital symbol per polarization is received in each of the plurality of time slots, divide each of the two sequences into a plurality of groups using a modulo operation of time, wherein each group comprises two digital symbols received in two consecutive time slots, and adaptively equalize the four digital symbols of the two consecutive time slots using a 4×4 matrix to generate four modulated symbols, wherein the 4×4 matrix comprises 16 tap-vectors.
