Coax/fiber hybrid access network for microcellular personal communication systems

A hybrid network architecture using subcarrier multiplexed optical fiber (SCMOL) and coaxial cable is proposed in this payer For the access Link of future personal communication systems (PCS) between tiny passive radio base stations in microcells and remote central base stations. Results indicate that the required number of laser diodes, photodetectors and amount of fiber could be reduced by more than 4 times with the proposed hybrid access link compared to the point-to-point SCMOL link and the network cost would decrease proportionally.
