  • System and method for interoperating a radio-over-fiber based network in a fiber-to-the-home network
    Patent number: 9419715
    Abstract: The present invention relates to a system for interoperating a full-duplex radio-over-fiber (RoF) network in a fiber-to-the-home (FTTH) network and to a method associated with the system. The system comprises, at the central station (100), a laser diode (105a), a first optical circulator (105b), an optical carrier generating unit (105c), and a second optical circulator (105d). The system comprises, at a base station (101), a third optical circulator (101a) a band pass filter (101b) coupled to the third optical circulator (101a) and configured to select only the optical signal having a corresponding pass band in which is used for converting an uplink signal as a remote local oscillator signal. The unselected optical signal is transmitted as downlink data.
