Multi-port accumulator for radio-over-fiber (RoF) wireless picocellular systems
First Claim
1. A multi-port accumulator apparatus for operably supporting two or more radio-over-fiber (RoF) transponders and for providing a connection to a tail cable that carries uplink and downlink optical signals and electrical power, comprising:
- a housing;
two or more RoF transponder ports supported by the housing, with each RoF transponder port configured to operably connect to one of the RoF transponders;
a tail cable port supported by the housing and configured to operably connect to the tail cable, the tail cable port being optically and electrically connected to each RoF transponder port so as to provide the uplink and downlink optical signals and the electrical power to each RoF transponder.

Abstract
A multi-port accumulator apparatus for a radio-over-fiber (RoF) wireless picocellular system that includes a housing that supports a tail cable port and a number of RoF transponder ports. The tail cable port is optically coupled to the RoF transponder ports so as to provide for optical 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 each transponder port so as to provide electrical power to each of the plurality of transponder ports. The multi-port accumulator supports two or more RoF transponders, one at each RoF transponder port. Each RoF transponder includes a directional antenna system that forms a picocellular coverage sub-area, with the combined sub-areas constituting a picocellular coverage area for the multi-port accumulator. The multi-port accumulator allows for the quick installation and deployment of large numbers of RoF transponders without having to individually connect each RoF transponder to a pair of downlink and uplink optical fibers carried by an optical fiber RF communication link.
