title: Bidirectional direct modulation CATV and phase remodulation radio-over-fiber transport systems.
abstract: A bidirectional lightwave transport system employing direct modulation CATV and phase remodulation radio-over-fiber (ROF) signals in two-way transmission is proposed and experimentally demonstrated. To be the first system of reusing the phase of the transmitting lightwave with multi-carrier analog CATV signal, the transmission performances of CATV and ROF signals are investigated in bidirectional way, with the help of optical band-pass filters (OBPFs) at the receiving sites. Through a serious investigation, the transmitting light sources are successfully remodulated with RF signals for transmission. Brilliant transmission performances of composite second-order (CSO), composite triple-beat (CTB), and bit error rate (BER) were obtained; accompanied with acceptable carrier-to-noise ratio (CNR) value. This proposed system reveals a prominent one with economy and convenience to be installed.
