Abstract

This study presents an externally modulated NTSC AM-vestigial side-band (VSB) erbium-doped fiber amplifier-repeated system that uses the optical VSB modulation technique to improve the systems´ composite second order (CSO) and composite triple beat (CTB) performances. In comparison with conventional externally modulated fiber optical CATV systems, excellent performances of carrier-to-noise ratio /spl ges/50 dB, CSO /spl ges/69 dB, and CTB /spl ges/68 dB were achieved for the full channel band over a 100-km single-mode fiber transport. This proposed system is suitable for fiber optical CATV systems in long-haul transport.
