Intra-Channel Chromatic Dispersion Measurements with Live Neighboring Signals in a Long Haul DWDM System

Not Accessible

Your library or personal account may give you access

Abstract

A novel four-tone probe signal is used to measure end-to-end residual chromatic dispersion in single 50-GHz DWDM channels of a long-haul ROADM network while transmitting more than 30 live signals in neighboring channels.
