    • A radio-over-fiber (RoF) hybrid wired/wireless transponder is disclosed that is configured to provide both wireless and wired communication between a hybrid head-end and one or more client devices. The hybrid transponder includes optical-to-electrical (O/E) and electrical-to-optical (E/O) conversion capability and is configured to frequency multiplex/demultiplex electrical “wired” signals and electrical “wireless” signals. The electrical wireless signals are wirelessly communicated to the client device(s) via a multiple-input/multiple-output (MIMO) antenna system within a cellular coverage area. The electrical wired signals are communicated to the client device(s) via a wireline cable that plugs into a wireline cable port on the transponder. The hybrid RoF system includes a hybrid head-end capable of transmitting and receiving wired and wireless optical signals, and an optical fiber cable that is optically coupled to the hybrid head-end and to at least one hybrid transponder. Drop-down transponder configurations that allow for easy wired and wireless connectivity between the client device(s) to the transponder(s) are also disclosed.

    • An optically-switched fiber optic communication system, such as a Radio-over-Fiber (RoF) based optical fiber link system, may be used to increase the range of peer-to-peer communications. The optically-switched fiber optic communication system may include a head-end unit (HEU) having an optical switch bank. Fiber optic cables comprising optical fibers optically couple the HEU to one or more remote access points in different coverage areas. The optical switch bank in the HEU provides a link between the remote access points in the different coverage areas such that devices in the different cellular coverage areas can communicate with each other over the optical fibers through the HEU. By using the optically-switched fiber optic communication system, the range and coverage of communication between devices may be extended such that devices in different coverage areas and devices using different communication protocols can communicate.
