Bidirectional WDM-RoF transmission for wired and wireless signals

The architectures of wired/wireless signal transmission based on RoF access network are proposed and their experimental results are shown. Both a wired and a wireless signals with a same data and heterogeneous data in different schemes are simultaneously generated using an injection locking technique and optical carrier suppression modulation based on a Fabry-Perot laser as a cost-effective WDM optical source. A reflective semiconductor optical amplifier (RSOA) is employed for the purpose of a colorless and simple base station. 20-km optical transmissions of 1.25-Gb/s wired and wireless data are experimentally demonstrated to verify the proposed RoF systems.
