Abstract
An optical communication system includes an optical transmission line with a pump laser port, a transmitter in communication with a multilevel coded electrical input signal and in communication with the optical transmission line, and a pump laser optically connected to the pump laser port. In the optical communication system, the optical transmission line and the pump laser are adapted to act in cooperation to amplify an optical signal traveling through the optical transmission line over at least a portion of a length of the transmission line.
