Abstract

This study presents a directly modulated 1550 nm NTSC AM-VSB 74-channel fiber optical CATV long-distance (over 100km) transmission system. In this system, 1550 nm analog distributed feedback (DFB) laser diodes, push-pull preamplifier, half-split-band, wavelength-division-multiplexing (WDM), and in-line erbium- doped fiber amplifiers (EDFAs) were used. Performances of carrier-to-noise ratio (CNR) of ≥ 49 dB, compositie second order (CSO) of ≥ 70 dB, and composite triple beat (CTB) of ≥ 65 dB were obtained over 100 km of standard single-mode fiber (SMF) transmission. This proposed directly modulated transmission system is simpler and more cost-effective than conventionally externally modulated 1550 nm transmission systems.
