What is BS EN 60728-11 - Cable networks for television signals, sound signals and interactive services about?
BS EN 60728 is a series on cable networks for television signals, sound signals and interactive services. Cable networks for television signals, sound signals and interactive services 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 60728-11 deals with the safety requirements applicable to fixed sited systems and equipment. As far as applicable, it is also valid for mobile and temporarily installed systems, for example, caravans.
Additional requirements may be applied, for example, referring to:
- Electrical installations of buildings and overhead lines
- Other telecommunication services distribution systems
- Water distribution systems
- Gas distribution systems
- Lightning systems
BS EN 60728-11 is intended to provide requirements specifically for the safety of the system, personnel working on it, subscribers and subscriber equipment. BS EN 60728-11 deals only with safety aspects and is not intended to define a standard for the protection of the equipment used in the system.
Who is BS EN 60728-11 - Cable networks for television signals, sound signals and interactive services for?
BS EN 60728-11 on cable networks is useful for:
- Television providers
- Radio equipment manufacturers
- Cell phone manufacturers
- Design engineers
- Quality control personnel
- Gas distributers
- Water distribution plants
- Electricity supply departments
Why should you use BS EN 60728-11 - Cable networks for television signals, sound signals and interactive services?
Different types of network cables, such as coaxial cables, optical fibre cables, and twisted pair cables, are used depending on the network's physical layer, topology, and size. BS EN 60728-11 deals 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.
Regional and local broadband cable networks, extended satellite and terrestrial television distribution networks and 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 are included for the implementation of BS EN 60728-11. The extent of BS EN 60728-11 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 of the customer premises equipment. BS EN 60728-11 will consider coexistence with users of the RF spectrum in wired and wireless transmission systems. Using BS EN 60728-11 you can deal with the safety requirements applicable to fixed sited systems and equipment.
