Abstract :
An architecture of an externally modulated AM-VSB CATV 77-channel erbium-doped fiber amplifier (EDFA)-repeated system which use the combination of a single-mode fiber (SMF) and reverse dispersion fiber (RDF) as a dispersion compensation device is proposed and demonstrated. Compared to the conventional externally modulated fiber optical CATV systems with or without a dispersion compensation fiber (DCF), excellent performance of composite second order (CSO) ≥ 78 dB accompanied by satisfied carrier-to-noise ratio (CNR) ≥ 50 dB and composite triple beat (CTB) ≥ 65 dB was obtained in the proposed system.
