Abstract
A directly modulated NTSC 77-channel fiber optical CATV transport system based on split-band and only one sideband techniques is proposed and demonstrated. Good performances of carrier-to-noise ratio (CNR), composite second-order (CSO) and composite triple beat (CTB) were obtained in our proposed systems over a 100 km standard single-mode fiber (SMF) transmission. Since an expensive externally modulated transmitter, sophisticated optical single sideband (SSB) modulation and stimulated Brillouin scattering (SBS) suppression techniques are not used, it reveals an outstanding system with simplicity and economic advantages over that of an externally modulated transport system.
