What is BS EN 50083-8 - Cable networks for television signals, sound signals and interactive services about?
BS EN 50083 is a series on cable networks for television signals, sound signals, and interactive services. 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 50083-8 applies to the radiation characteristics and immunity to electromagnetic disturbance of cable networks for television signals, sound signals and interactive services and covers the frequency range 0,15 MHz to 3,5 GHz. It should be noted that measurements below 30 MHz are not generally considered useful in the context of cable networks and are difficult to perform in practice. Application of the harmonized standard EN 50529-2 provides a presumption of conformance to the EMC Directive. Therefore, to fulfil the requirements of EN 50529-2, it is necessary to use cable network equipment that satisfies the requirements of EN 50083-2 regarding limits of radiation and of immunity to external fields.
BS EN 50083-8 specifies methods of measurement and EMC performance requirements under operating conditions (in situ) to ensure the ongoing EMC integrity of cable networks. The extent of BS EN 50083-8 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 of the customer premises equipment. BS EN 50083-8 consider coexistence with users of the RF spectrum in wired and wireless transmission systems.
Note: Cable networks beyond the system outlets (e.g., the receiver lead, in simplest terms) begin at the system outlet and end at the input to the subscriber's terminal equipment are not covered by BS EN 50083-8.
Note 2: 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 50083-8 - Cable networks for television signals, sound signals and interactive services for?
BS EN 50083-8 on cable networks is useful for:
- Telecommunication component manufacturers
- Telecommunication equipment manufacturers
- Design engineers
- Quality control personnel
Why should you use BS EN 50083-8 - Cable networks for television signals, sound signals and interactive services?
Standards of the EN 50083 and EN 60728 series deal with cable networks including equipment and associated methods of measurement for headend reception, processing and distribution of television and sound signals and for processing, interfacing, and transmitting all kinds of data signals for interactive services using all applicable transmission media. These signals are typically transmitted in networks by frequency multiplexing techniques.
BS EN 50083-8 includes regional and local broadband cable networks, extended satellite and terrestrial television distribution systems, individual satellite and terrestrial television receiving systems and all kinds of equipment, systems and installations used in such cable networks, distribution and receiving systems. Cable networks and a wide range of radio services have to coexist. These include for example emergency services, the safety of life, broadcasting, aeronautical, radio navigation services and also land mobile, amateur and cellular radio services. Frequency ranges of typical safety of life services are listed in BS EN 50083-8. Additional protection for certain services may be required by national regulations. Using BS EN 50083-8 you can specify the radiation characteristics and immunity to electromagnetic disturbance of cable networks for television signals, sound signals and interactive services and covers the frequency range 0,15 MHz to 3,5 GHz.
What’s changed since the last update?
BS EN 50083-8:2013 supersedes BS EN 50083-8:2002+A11:2008. BS EN 50083-8:2013 includes some technical changes with respect to BS EN 50083-8:2002+A11:2008. These include:
- EN 50083-8 with its methods of measurement and EMC performance requirements is explicitly dedicated to “under operating conditions (in situ)” to ensure the ongoing EMC integrity of cable networks
- The harmonized standard EN 50529-2 is dedicated or the provision of presumption of conformance to the EMC Directive
- The first intermediate frequency range (1st IF range) for satellite signal transmission was extended to cover now frequencies from 950 MHz up to 3 500 MHz
- The method of measurement and the requirements for in-band immunity were extended considering the new EMC environment due to the allocation of broadband wireless services in the frequency band 790 MHz to 862 MHz. As a consequence, the limits of in-band immunity were specified for analogue and additionally digital signals in this frequency range
- The substitution method of measurement (power method) was deleted
