SIST EN 50083-4:1995

Cabled distribution systems for television and sound signals -- Part 4: Passive coaxial wideband distribution equipment

This standard applies to receiver leads, system outlets, splitters and subscriber taps, passive one and two port devices comprising filters, attenuators, equalizers, galvanic isolators, power injectors, cable splices, terminating resistors and transfer points, but excluding coaxial cables. It - covers the frequency range 5 MHz to 1 750 MHz; - identifies performance requirements for certain parameters; - lays down data publication requirements for certain parameters; - stipulates methods of measurement; - introduces minimum requirements defining quality (Q) grade(s). There are three Q grades for taps and splitters and two Q grades for passive one and two port devices. There is only one Q grade for system outlet and receiver lead. Different networks require the same performance and, when integrating networks, upgrading will be avoided. 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 optimize cost/performance, taking into account the size of the network and local circumstances. All requirements and published data shall be understood as guaranteed values within the specified frequency range and in well matched conditions. For passive equipment of quality grades other than mentioned above, manufacturers shall specify minimum values for : - return loss; - isolation; - directivity; using the relevant measurement methods and the presentation of table 1.
