Abstract :
A hybrid cable television/radio-over-fiber (ROF) transport system with direction modulation of cable television signals and the polarization modulation of ROF signals is proposed and experimentally demonstrated for the first time. When a multicarrier cable television signal in the optical amplitude domain and an ROF signal in the optical polarization domain are modulated, a single optical wavelength can serve these two signal applications simultaneously. This hybrid transport system not only satisfied the cable television requirements, but also satisfied the demand for high-quality ROF transmission over a 20-km single-mode fiber.
