Определение hfc в Английский Язык Английский Язык словарь
- hydrofluorocarbon, a class of molecules containing hydrogen, fluorine and carbon atoms
- (Ecology) gas that was used to replace ozone-depleting gases (was later found to contribute to global warming)
- (Hybrid Fibre Coaxial cable)A shared broadband access architecture using optical fibre between exchanges and hubs in suburban streets, and coaxial cables between the hubs and customers to carry Foxtel pay TV and TM cable services
- Hybrid Fiber Coaxial cable
- Hybrid Fiber Coax (=SMFCB)
- Older Cable TV systems were provisioned using only coaxial cable Modern systems use fiber transport from the headend to an optical node located in the neighborhood to reduce system noise Coaxial cable runs from the node to the subscriber The fiber plant is generally a star configuration with all optical node fibers terminating at a headend The coaxial cable part of the system is generally a trunk-and-branch configuration
- Hybrid fibre/coax Close this window
- Hybrid Fiber Coaxial
- Combination of fiber optics and conventional coaxial cable that supports residential two-way, high-speed data access
- a fluorocarbon emitted as a by-product of industrial manufacturing
- Hybrid fiber-coax
- Hybrid Fibre-Coax
- Hybrid Fibre Coax: a system (usually CATV) where fibre is run to a distribution point close to the subscriber and then the signal is converted to run to the subscriber's premises over coaxial cable
- Hybrid Fiber/Coaxial
- Hydro fluoro carbons, non-ozone depleting replacement for CFCs
- Hybrid Fiber Coax
- High-band Fiber-optic Cable; Hybrid Fiber/Coax
- Hydrofluorocarbon
- (hydrofluorocarbons) are greenhouse gases and have a high global warming potential
- Hybrid Fiber Coax is a way of delivering video, voice telephony, data, and other interactive services over coaxial and fiber optic cables An HFC network works consists of a head-end office, distribution center, fiber nodes, and network interface units The head-end office receives information such as television signals, Internet packets, and streaming media, then delivers them through a SONET ring to distribution centers The distribution centers then send the signals to neighborhood fiber nodes, which convert the optical signals to electrical signals and redistributes them on coaxial cables to residents' homes where network interface units send the appropriate signals to the appropriate devices (i e television, computer, telephone)
- A transmission system or cable construction (illustrated) that incorporates both fiber optic transmission components and copper coax transmission components
- Hybrid Fiber/Coax: a broadband deployment strategy that uses fiber from the central office/head end out to the subscriber's area, then uses coaxial cable to reach the subscriber
- Hybrid fiber-coaxial
