Abstract
A full-duplex, optical feeder network for wireless access operating at 39 GHz is presented. The system transports 155 Mbit/s of data and three video channels downstream, and 51.8 Mbit/s upstream over 40 km of standard singlemode fibre. The 39 GHz carrier signal was generated using a novel tripling technique which enables low frequency electronics and optical components to be implemented in the central office. The architecture also incorporates simple, low cost remote base-stations with no millimetre-wave upconverting mixers required. To further minimise cost, an LED was used as the optical source for upstream transmission.
