TELECOMMUNICATION CABLES – Long Distance Communication
The ever increasing requirements for speed and bandwidth lead to the development of telecommunication cables using fibre optic technology, replacing the traditional copper conductor in new installations for the transmission of communication signals over long distances. While offering all technologies, Europacable member companies believe that optical fibre cable technology will be most suited to ensure the deployment of future proof grids.
Telecommunication cables are used when connecting a number of end users to a central point known as an ‘Access Node’ or ‘Point of Presence’ (POP). Each Access Node contains the necessary electronic transmission (active) equipment to provide the applications and services to the subscriber. Each Access Node, within a large municipality or region, is connected to a larger metropolitan or urban optical fibre network.
Today, different telecommunication cable technologies are currently available:
|Optical fibre cables contain single or multiple fibre optical ribbons installed in tubes. Opitcal fibre cables offer unlimited bandwith and are therefore very apt for future proof girds. They can be directly buried or blown into ducts.|
|Twisted multi pair copper cables – shielded or unshielded – are typically made with copper wires with coloured insulation made of polyethylene and PVs or halogen free jackets. Twisted pair cables are found in many Ethernet networks and telephone systems.|
|Coaxial cables can be used as an alternative to copper pairs. Coaxial cables conduct electrical signal using an inner conductor surrounded by an insulating layer and all enclosed by a shield, typically one to four layers of woven metallic braid and metallic tape.|
