Digital return path for hybrid fiber/coax network

摘要

A hybrid fiber/coax network is provided. The network includes a head end with at least one optical distribution node coupled to the head end over at least one fiber optic link. A plurality of coaxial cable links are coupled to each of the at least one optical distribution node. Further, a transmitter is disposed at the optical distribution node. The transmitter is responsive to signals from the plurality of coaxial cable links. The transmitter converts analog signals to baseband digital signals and transmits the baseband digital signals to the head end over the at least one optical link. A receiver is disposed at the head end. The receiver is responsive to the digital signals from the transmitter and converts the digital signals to analog signals for the head end.
