Abstract :
We have experimentally demonstrated a novel wavelength reuse scheme for up-link connection in a radio-over-fiber (ROF) system. The dual-mode lightwave generated by optical carrier suppression modulation is separated by an optical interleaver. One of the dual-mode lightwaves is modulated with a baseband data at 2.5 Gb/s. The other lightwave will be used for the optical carrier for the up-link data modulation. There is no additional laser source for the upstream data generation in the base station. By this method, we simplify the configuration of the ROF system and reduce the cost of the system
