Abstract : During 1985 Bristish Telecom commmenced the installation of a number of cable television systems in the United Kingdom. One of these systems, in Westminster, London, is of the Switched Star type, developed by the British Telecom Research Laboratories. The network comprises optical fibre cable between the head-end and the cabinet-mounted switch, and coaxial cable between the switch and the customer. A number of new outside plant products have been developed to meet the special requirements of the Westminister installation. This earlier work, together with the experience gained from the installation of optical fibres in the British Telecom trunk and junction networks, formed an ideal basis for evolving the line plant necessary to enable BT to introduce singlemode optical fibre into the local network. A range of cables is being developed by UK companies, suitable for installing in the harsh environment of the local network. Joint organisers and flexibility nodes are being introduced, both for underground application and for within the exchange and customer's premises. In addition blown-fibre techniques are being used to introduce fibre into these networks.
