Abstract :
The ON/OFF ratio of a high-density WDM system can be degraded by Raman crosstalk. The worst case degradation is considered. Severe degradation is possible for systems with a large channel number and high transmitted signal level. The degradation may set a limit on the number of channels, the transmitted signal level, and the initial ON/OFF ratio.
