Abstract

We propose and demonstrate an externally modulated national television system committee (NTSC) 77-channel erbium-doped fiber amplifier-repeated system employing an optical single sideband filter at the receiving site. In comparison with conventional externally modulated fiber-optical CATV systems, excellent performances of carrier-to-noise ratio ≥50 dB, composite second order ≥70 dB, and composite triple beat ≥69 dB were achieved for the full channel band over a 100-km single-mode fiber transport. Our proposed system is suitable for the long-haul fiber-optical CATV system.
