MULTI-PORT ACCUMULATOR FOR RADIO-OVER-FIBER (RoF) WIRELESS PICOCELLULAR SYSTEMS
First Claim
1. A radio over fiber (RoF) wireless picocellular system, comprising:
- a head-end unit configured to be optically connected to an outside network;
a distribution unit optically coupled to the head-end unit via a primary optical fiber RF communications link, the distribution unit configured to divide the primary optical fiber RF communication link into a plurality of tail cables; and
a plurality of multi-port accumulators, each of the plurality of multi-port accumulators receiving a tail cable among the plurality of tail cables, and each of the plurality of multi-port accumulators including at least two transponders,wherein each of the at least two transponders is coupled to the primary optical fiber RF communication link and is configured to form a picocell coverage area and to wirelessly communicate with a client device within the picocell coverage area.

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.
