Paper Abstract

Optical performance monitoring is an import issue for the design, operation and maintenance of optical transport networks (OTN). Pilot tone detection is one of the monitoring techniques used in all-optical WDM networks [1]. This technique is very simple and could monitor both the optical paths and switch failures in a large-scale WDM transport networks. But the effect of Stimulated Roman Scattering (SRS) could product ghost tone that will suppress the capability of pilot-tone based monitoring technique. We give a simple model to analyze the effects of Stimulated Raman Scattering on pilot-tone base WDM supervisory technique.
