EN 50083-3:1994

EN 50083-3:1994 is a standard published by CLC. Its full title is "Cabled distribution systems for television and sound signals - Part 3: Active coaxial wideband distribution equipment". This standard covers: This standard - applies to all broadband amplifiers used in cabled distribution systems; - covers the frequency range 5 MHz to 1 750 MHz; - applies to one-way and two-way equipment; - lays down the basic methods of measurement of the operational characteristics of the active equipment in order to assess the performance of this equipment; - identifies the performance specifications that shall be published by the manufacturers; - states the minimum performance requirements of certain parameters. Amplifiers are divided into the following two quality levels: Grade 1 - Amplifiers typically intended to be cascaded. Grade 2 - Amplifiers for use typically within an apartment block, or within a single residence, to feed a few outlets. Practical experience has shown these types meet most of the technical requirements necessary for supplying a minimum signal quality to the subscribers. This classification shall not be considered as a requirement but as the information for users and manufacturers on the minimum quality criteria of the material required to install networks of different sizes. The system operator has to select appropriate material to meet the minimum signal quality at the subscriber's outlet, and to optimise cost/performance, taking into account the size of the network and local circumstances. All requirements and published data are understood as guaranteed values within the specified frequency range and in well matched conditions.
