This part of IEC 60728 lays down the measuring methods, performance requirements and data publication requirements for active wideband equipment of cable networks for television signals, sound signals and interactive services. This standard · applies to all broadband amplifiers used in cable networks; · covers the frequency range 5 MHz to 3 000 MHz; NOTE The upper limit of 3 000 MHz is an example, but not a strict value. The frequency range, or ranges, over which the equipment is specified, should be published. · 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 to 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 that these types meet most of the technical requirements necessary for supplying a minimum signal quality to the subscribers. This classification is not a requirement but is provided to users and manufacturers for information about 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.

Cable networks for television signals, sound signals and interactive services - Part 4: Passive wideband equipment for coaxial cable networks (IEC 60728-4:2007)

IEC 60728-4:2007 电视信号、声音信号和交互式服务用电缆网络.第4部分:同轴电缆网络用无源宽带设备(TA 5)

This part of IEC 60728 applies to system outlets, splitters and taps, passive single or multiple port equipment comprising filters, attenuators, equalizers, galvanic isolators, power injectors, cable splices, terminating resistors and transfer points, but excluding coaxial cables and receiver leads (see 5.2). This standard • covers the frequency range 5 MHz to 3 000 MHz; • identifies performance requirements for certain parameters; • lays down data publication requirements for certain parameters; • stipulates methods of measurements; • introduces minimum requirements defining quality grades. There are three grades for all passive equipment except system outlets where there is only one. Different networks require the same performance and, when integrating networks, upgrading will be avoided. Practical experience has shown that these three grades meet most of the technical requirements necessary for supplying a minimum signal quality to the subscribers. This classification should not be considered as a requirement but as information for users and manufacturers on the minimum quality criteria of the material required to install networks of different sizes. The system operator should 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 should be understood as guaranteed values within the specified frequency range and in well-matched conditions.
