A two-wavelength wavelength-division-multiplexing (WDM) CATV transport system that employed polarization modulation (PolM) technique to reduce the self-phase modulation (SPM) and crosstalk is proposed and demonstrated. In contrast to a two-wavelength WDM CATV transport system used intensity modulation (IM) technique, good performances of composite second order (CSO) and composite triple beat (CTB) were obtained accompanied by acceptable carrier-to-noise ratio (CNR) value in our proposed system over a 100-km single-mode fiber (SMF) transmission.
