What is BS EN 50083-2 - Cable networks for television signals, sound signals and interactive service about?
BS EN 50083-2 is a series on cable networks for television signals, sound signals and interactive service.
Cable networks are networking hardware used to connect one network device to other network devices or to connect two or more computers to share printers, scanners etc.
BS EN 50083-2 deals with cable networks including equipment and associated methods of measurement for headend reception, processing and distribution of television signals, sound signals and their associated data signals and for processing, interfacing and transmitting all kinds of signals for interactive services using all applicable transmission media.
BS EN 50083-2 includes:
- CATV-networks 1)
- MATV-networks and SMATV-networks
- Individual receiving networks
and all kinds of equipment, systems and installations installed in such networks. The extent of BS EN 50083-2 is from the antennas and/or special signal source inputs to the headend or other interface points to the network up to the terminal input.
Note: The standardization of any user terminals (i.e., tuners, receivers, decoders, multimedia terminals, etc.) as well as of any coaxial, balanced and optical cables and accessories thereof is excluded.
Who is BS EN 50083-2 - Cable networks for television signals, sound signals and interactive service for?
BS EN 50083-2 on cable networks for television signals, sound signals and interactive service is useful for:
- Telecommunication component manufacturers
- Telecommunication equipment manufacturers
- Design engineers
- Quality control personnel
Why should you use BS EN 50083-2 - Cable networks for television signals, sound signals and interactive service?
Different types of network cables, such as coaxial cables, optical fibre cables, and twisted pair cables, are used depending on the network's physical layer, topology, and size. BS EN 50083-2 describes a method that is applicable to the measurement of disturbance voltages from equipment in the frequency range of 150 kHz to 30 MHz on the mains line. The measured voltage includes narrowband interference and broadband interference such as that produced by semiconductor rectifiers.
BS EN 50083-2 applies to the radiation characteristics and immunity to electromagnetic disturbance of EM-active equipment (active and passive equipment) for the reception, processing and distribution of television, sound and interactive multimedia signals and covers frequency ranges of disturbance voltage injected into the mains, radiation from active equipment, immunity of active equipment and screening effectiveness of passive equipment. BS EN 50083-2 also specifies requirements for the maximum allowed radiation, minimum immunity and minimum screening effectiveness and describes test methods for conformance testing. Due to the fact that cable networks, the former cabled distribution systems for television and sound signals are more and more used for interactive services, these networks may also incorporate equipment that carries besides the cable network equipment ports also one or more telecom signal ports. This equipment is named "multimedia network equipment".
Using BS EN 50083-2 you can understand cable networks including equipment and associated methods of measurement for headend reception, processing and distribution of television signals, sound signals and their associated data signals and for processing, interfacing, and transmitting all kinds of signals.
