Standards of the EN 50083<\/span> <\/span> and EN 60728<\/span> <\/span> series deal 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.<\/p>\n This includes<\/p>\n CATV-networks 1)<\/sup> <\/span> ,<\/p>\n<\/li>\n MATV-networks and SMATV-networks,<\/p>\n<\/li>\n individual receiving networks<\/p>\n<\/li>\n<\/ul>\n and all kinds of equipment, systems and installations installed in such networks.<\/p>\n The extent of this standardisation work 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.<\/p>\n The standardisation 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.<\/p>\n This European Standard<\/p>\n 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 as dealt with in the following parts of EN 50083<\/span> <\/span> or EN 60728<\/span> <\/span> series:<\/p>\n EN 60728\u20113<\/span> <\/span> “Active wideband equipment for cable networks”;<\/p>\n<\/li>\n EN 60728\u20114<\/span> <\/span> “Passive wideband equipment for coaxial cable networks”;<\/p>\n<\/li>\n EN 60728\u20115<\/span> <\/span> “Headend equipment”;<\/p>\n<\/li>\n EN 60728\u20116<\/span> <\/span> “Optical equipment”;<\/p>\n<\/li>\n<\/ul>\n<\/li>\n covers the following frequency ranges:<\/p>\n specifies requirements for maximum allowed radiation, minimum immunity and minimum screening effectiveness;<\/p>\n<\/li>\n describes test methods for conformance testing.<\/p>\n<\/li>\n<\/ul>\n No measurement needs to be performed at frequencies where no requirement is specified.<\/p>\n 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 incorporate also equipment that carry besides the cable network equipment ports also one or more telecom signal port(s). This equipment shall be named as “multimedia network equipment”.<\/p>\n The EMC behaviour of cable network equipment, telecommunication network equipment and multimedia network equipment may be described by the following port structure ( Table 1<\/span>):<\/p>\n Table 1<\/span> shows that cable network equipment and telecommunication network equipment have four common ports and, respectively, two and one individual ports. Multimedia network equipment carry besides the common ports an antenna input port and\/or a RF network port as well as a telecom signal port.<\/p>\n The electromagnetic compatibility requirements for “telecommunication network equipment only” are standardised in ETSI EN 300 386<\/span> <\/span> (mainly) and in ETSI EN 301 489\u20114<\/span> <\/span> , those for “cable network equipment only” are given in this EN 50083\u20112<\/span> <\/span> .<\/p>\n Equipment for multimedia networks of the above-mentioned type has to work under the same EMC conditions as equipment that is falling under the cable network and the telecommunication network EMC-standards. Due to the fact, that this equipment has to work in close proximity, e.g. in the same operating room, the EMC environmental conditions for all three types of equipment are the same.<\/p>\n This means that multimedia network equipment has to fulfil the EMC requirements of one of the above mentioned standards and in addition the EMC requirements, laid down in the other EMC standard, for the additional port, by which it is connected to the other network.<\/p>\n By this procedure it is ensured that multimedia network equipment fulfils the EMC conditions of one of the above mentioned networks and will neither disturb the respective other system nor will be disturbed by the respective other system via the connecting port.<\/p>\n Coaxial cables for cable networks do not fall under the scope of this standard; reference is made to EN 50117<\/span> <\/span> series. Coaxial cable assemblies for radio and TV receivers (receiver leads) do not fall under the scope of this standard; reference is made to EN 60966<\/span> <\/span> series. Requirements for the electromagnetic compatibility of receiver leads are laid down in EN 60966\u20112\u20114<\/span> <\/span> , EN 60966\u20112\u20115<\/span> <\/span> and EN 60966\u20112\u20116<\/span> <\/span> .<\/p>\n This European Standard also covers indoor receiving antennas for broadcast signals for which the requirements and the applicable methods of measurement are limited to the emission and the electrostatic discharge phenomena.<\/p>\n Standardisation in the field of “Electromagnetic compatibility” for any broadcast terminals (e.g. tuners, receivers, decoders, etc.) is covered by EN 55013<\/span> <\/span> and EN 55020<\/span> <\/span> and for multimedia terminals by EN 55022<\/span> <\/span> and EN 55024<\/span> <\/span> .<\/p>\n","protected":false},"excerpt":{"rendered":" Cable networks for television signals, sound signals and interactive services – Electromagnetic compatibility for equipment<\/b><\/p>\n\n
