hfc

HFC is an acronym that can refer to multiple topics in science and technology. The two most common uses are hydrofluorocarbons and hybrid fiber-coaxial networks.

Hydrofluorocarbons (HFCs) are a class of synthetic greenhouse gases containing hydrogen, fluorine, and carbon. They are used as refrigerants in air conditioners and refrigerators, as foam blowing agents, and as solvents. They have high global warming potentials and do not deplete ozone. Due to their impact on climate, HFCs are subject to regulation under the Montreal Protocol and its amendments, notably the Kigali Amendment, which mandates phasedown of their production and use. Alternatives include hydrofluoroolefins and natural refrigerants. Phasedown schedules vary by country.

Hybrid fiber-coaxial networks (HFC) are telecommunications networks that combine optical fiber and coaxial cable. A fiber backbone runs to a distribution point, with coaxial cable delivering services to individual homes. This architecture enables broadband internet, digital cable television, and VoIP services, often using DOCSIS standards. Capacity improvements and network upgrades have focused on increasing fiber reach and upgrading node bandwidth, enabling higher downstream and upstream speeds.

In other contexts, HFC may appear as an acronym in specific organizations or technical standards; readers should use context to disambiguate.
