HYBRID FIBER/COAX VIDEO AND TELEPHONY COMMUNICATION SYSTEM |
摘要 |
A video and telephony signal distribution network having a head end including an optical transmitter for transmitting optical downstream video and telephony signals on at least one optical fiber in a first frequency bandwidth and a receiver for receiving optical upstream data signals. The network further includes at least one optical/electrical converter unit which includes a receiver for receiving the optical downstream video and telephony signals and converts the optical downstream video and telephony signals into a plurality of downstream electrical output signals. A coaxial distribution system provides for transmission of one of the downstream electrical output signals from the optical/electrical converter unit to a service unit connected to at least one remote unit. The service unit includes a transmitter for transmitting upstream electrical data signals generated at the remote units via a coaxial distribution system to an optical/electrical converter unit connected thereto within a second frequency bandwidth. The second frequency bandwidth is reused for transmission by each service unit connected to each remote unit. The optical/electrical converter unit receives the upstream electrical data signals from a plurality of the service units and converts the upstream electrical data signals for transmittal as an optical upstream data signal to the head end.
