Abstract
A multi-port accumulator apparatus for a radio-over-fiber (RoF) wireless picocellular system comprising a housing supporting a tail cable port and transponder ports. The tail cable port is optically coupled to the RoF transponder ports to provide for transmission of uplink and downlink optical signals between the tail cable port and each of the transponder ports. The tail cable port is also electrically coupled to provide power to each transponder port. The multi-port accumulator supports RoF transponders, one at each of the transponder ports. Each RoF transponder includes a directional antenna system forming a picocellular coverage sub-area, with the combined sub-areas constituting a picocellular coverage area for the multi-port accumulator. The multi-port accumulator permits quick installation and deployment of large numbers of RoF transponders without individually connecting each RoF transponder to downlink and uplink optical fibers in an optical fiber RF communication link.
