Paper Abstract

A potentially cost-effective radio-over-fiber (ROF)/fiber-to-the-X (FTTX)/CATV hybrid three-band transport system based on direct modulation of a distributed feedback laser diode (DFB LD) with multi-wavelength output characteristic is proposed and experimentally demonstrated. Directly modulated radio-frequency (RF) (1.25Gbps/6GHz), externally remodulated baseband (BB) (622 Mbps), and externally remodulated CATV (channels 2-78) signals are successfully transmitted simultaneously. Over an 80-km single-mode fiber (SMF) transmission, low bit error rate (BER) and clear eye diagram were achieved for ROF and FTTX applications; and good performances of carrier-to-noise ratio (CNR), composite second-order (CSO) and composite triple beat (CTB) were obtained for CATV signals. Since our proposed systems use only a directly modulated DFB LD to achieve multi-wavelength transmission, it reveals an outstanding one with simpler and more economic advantages.
