Abstract
An HFC return path system uses digital conversion and transport at the fiber optic node, so as to replace analog laser technology with a high-speed baseband digital technology, thereby providing immunity from the troublesome analog laser impairments, enabling longer distances to be covered, potentially avoiding the need for hub repeater hardware required in analog systems, among other benefits.
