Hybrid fiber/coax video and telephony communication

摘要

A video and telephony signal distribution network is provided. The network includes a head end for transmitting to a plurality of remote units. The network further includes at least one optical/electrical converter unit that transmits to the remote units over at least two coaxial cables coupled to a common optical/electrical converter unit. Each remote unit transmits upstream electrical data signals over its associated coaxial cable to the optical/electrical converter unit using a common bandwidth. The optical/electrical converter unit converts and frequency shifts the upstream electrical data signals from at least one remote unit to form an optical upstream data signal for transmittal to the head end such that the frequency spectrum used for the upstream communications is simultaneously used on each of the coaxial cables of to optical/electrical converter unit.
