Abstract
A shared hybrid fiber-coax transmission system (100) includes at least one fiber node (180) that includes at least one receiver (460) for converting an upstream signal into a baseband digital format for conversion into a digitally modulated, optically-formatted signal for transmission to a head end (120). By converting the upstream signal into a digital baseband format for transmission in an optical format to the head end, ingress nose associated with the upstream signal can be reduced.
