Abstract

This paper presents a multi-service cable television (CATV) system using a single wavelength. The multi-service CATV systems can transmit both CATV and wireless signals by using one external modulator on a single wavelength over a single fiber. Moreover, this multi-service transport system, in contrast to the previously developed systems, does not incur the dc bias drift problem. In addition to satisfying the CATV requirements where excellent performances of carrier-to-noise ratio (CNR), composite second-order (CSO), and composite triple beat (CTB) are achieved for CATV signals, the multi-service transport system also satisfies the demand for high-quality wireless signal transmission over a 25-km single-mode fiber (SMF).
