Abstract
A hybrid fiber-coax network (100) includes at least one repeater (220.sub.1) dispersed within a coax trunk (22.sub.1) that carries video information downstream to a subscriber (14) and subscriber-originated information upstream to a fiber node (18). The repeater serves to digitally regenerate the subscriber-originated information to reduce ingress noise that would otherwise aggregate at the fiber node.
