Statistical Crosstalk Reduction Effect by Blank Channels in FDM/WDM Optical ADM for Digital Terrestrial Broadcast CATV Signals

Abstract

We report the statistical simulation results of the success probability of optical FDM/WDM Add-Drop-Mux (ADM) for CATV systems transferring terrestrial broadcast digital TV signals. Statistical simulation results show that the required signal crosstalk attenuation value of the optical notch filter can be reduced by inserting blank TV signal channels. The success probability value of the optical FDM/WDM Add-Drop-Mux can consequently be increased.
