Abstract: A broadband digital access (BDA) architecture includes a BDA hub device in a headend/hub and one or more BDA node modules in one or more HFC nodes to enable digital communications between the headend/hub and the HFC node(s) in a CATV/HFC network. The BDA hub device and the BDA node module(s) are connected by one or more downstream optical fibers and one or more upstream optical fibers to enable digital optical communications therebetween. The BDA hub device provides an analog RF interface with equipment in the headend/hub and the BDA node module provides an analog RF interface with subscriber locations via one or more coaxial cables.
