Optisystem based CATV System-Performance Improvement by Using External Light-Injection Technique

Abstract

Cable Television (CATV) is designed with erbium-doped amplifier-repeated system that uses an external light -injection technique and a directly modulated wave using amplitude modulation. The external lightinjection technique can greatly enhance the frequency response of the laser diode, and hence improve the overall performance of the fibre optical CATV system. It implemented using Optiwave Optisystem 10.0.
