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

S.Adithyan, S.Srinath

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 light – injection 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.
