Abstract

We propose and demonstrate a repeaterless directly modulated fiber optical CATV transport system based on half-split-band and remote light injection techniques. Good performances of carrier-to-noise ratio (CNR), composite second order (CSO) and composite triple beat (CTB) were obtained over a 50-km single mode fiber (SMF) transmission without optical amplification. Our proposed repeaterless directly modulated fiber optical CATV transport systems are simpler and cost lower than conventional externally modulated ones.
