Making High Speed Optical Networks Independent of the Optical Channel

摘要

High speed optical networks require optical transmission to be robust to noise as well as linear and non-linear distortions. Robustness to the time evolution and reconfiguration of the optical channel is also required. In this tutorial we discuss traditional optical modem and line technologies which have been deployed and, their relation to the above considerations. In addition, the significance of emerging digital optical-modem technology is explored.
