Abstract
An optical communication system has an optical transmitter, an optical transmission line in optical communication with the optical transmitter, an optical receiver in optical communication with the optical transmission line, and a dispersion compensator disposed between the optical transmitter and the optical receiver along the optical transmission line. The optical transmitter is adapted to transmit an optical signal that includes multilevel encoding. The optical transmission line causes a first dispersion of the optical signal and the dispersion compensator causes a second dispersion of the optical signal. The second dispersion at least partially cancels the first dispersion.
Claims25
An optical communication system, comprising:
- an optical transmitter;
- an optical transmission line in optical communication with said optical transmitter;
- an optical receiver in optical communication with said optical transmission line;
- and
- a dispersion compensator disposed between said optical transmitter and said optical receiver along said optical transmission line;
- wherein said optical transmitter is adapted to transmit an optical signal that includes multilevel encoding, and
- wherein said optical transmission line causes a first dispersion of said optical signal and said dispersion compensator causes a second dispersion of said optical signal, said second dispersion at least partially canceling said first dispersion.
A method of transmitting information, comprising:
- forming an optical signal comprising at least some multilevel encoding;
- transmitting said optical signal between a first location and a second location in a dispersive medium, said optical signal undergoing a first dispersion;
- and
- transmitting said optical signal through a dispersion compensator;
- said optical signal undergoing a second dispersion,
- wherein said second dispersion at least partially cancels said first dispersion.
