Dynamic Reconfigurable WDM 60GHz Millimeter-Wave-Band Radio-over-Fiber Access Network : Architectural Considerations and Experiment

摘要

We propose dynamic reconfigurable wavelength division multiplexed (WDM) millimeter-wave-band radio-over-fiber (RoF) access network and demonstrate for the first time dynamic channel allocation capability of millimeter-wave band RoF signals in WDM access network using a supercontinuum light source, arrayed-waveguide gratings and a reconfigurable optical crossconnect switch. The dynamic reconfigurable RoF network architecture is presented and its features described. Then, four 155 Mbps RoF channels are effectively generated, transmitted through 25 km of fiber, switched, and then transmitted again through 2 km of fiber and detected with error-free operation (bit error rate). The proposed RoF architecture is highly scalable, both in terms of channel counts and access point counts.
