Hybrid fiber-coaxial (HFC) is a broadband telecommunications network that combines optical fiber and coaxial cable. It has been commonly employed globally by cable television operators since the early 1990s.
Example of a cable modem installed in a home office. A cable modem is a type of network bridge that provides bi-directional data communication via radio frequency channels on a hybrid fiber-coaxial (HFC), radio frequency over glass (RFoG) and coaxial cable infrastructure.

A cable modem at the customer is connected via coaxial cable to an optical node, and thus into an HFC network. An optical node serves many modems as the modems are connected with coaxial cable to a coaxial cable "trunk" via distribution "taps" on the trunk, which then connects to the node, possibly using amplifiers along the trunk.
The new box, called XUMO, replaces the old set-top cable box and has several new features. Spectrum cable introduces a new souped-up ‘cable box.’ What it does, how much it costs
Data Over Cable Service Interface Specification (DOCSIS) is an international telecommunications standard that permits the addition of high-bandwidth data transfer to an existing cable television (CATV) system. It is used by many cable television operators to provide cable Internet access over their existing hybrid fiber-coaxial (HFC ...
Cable modem termination system. A cable modem termination system (CMTS, also called a CMTS Edge Router) [1] is a piece of equipment, typically located in a cable company's headend or hubsite, which is used to provide data services, such as cable Internet or Voice over IP, to cable subscribers.
The Telstra HFC network is being maintained – it was found that the Optus HFC network was uneconomic to bring up to an acceptable standard, with these connections now to be provided by FTTC. [97] HFC connections use a DOCSIS cable modem as their NTD. The upgrade path for Telstra HFC-connected premises is DOCSIS 3.1.
