At the beginning of the Decade of the eighties, the person in charge of the network of data within the Organization had to send information to the end users or data communication terminals. This person installing proprietary cabling systems as the coaxial RG 62 for IBM systems. Companies began creating its own rules for wiring installations, and so appeared systems of wiring owner. Subsequently, the Association of the industry of telecommunications (TIA) established what today is known as the standard 568 for wiring of commercial buildings, is related directly to the wiring system concept structured. A system of structured cabling is defined by opposition to the problems of the wiring not structured, not standard or closed, or owner of a particular manufacturer. A wiring system opened on the other hand, is a cabling system structured that it is designed to be independent of the provider and application at the same time.
The key of a cabling system features Open are all the outlets (outputs for connection) of the area of work are identically connected in Star for central distribution point, using a combination of hardware and media that can accept any need for application that can occur over the life of the wiring, which is estimated at around ten years. These features of the system wiring open offer three main advantages to the owner / user: to) since the cabling system is independent of the application and the provider, network and equipment changes can be made by the same existing wires. (b) since the outlets are wired in the same way, the movements of staff can do without changing the basis of wiring. (c) the location of the hubs and hubs on your network in a central distribution point, usually a telecommunications closet, allows that the wiring or network problems are detected and isolated easily without having to stop the rest of the network. It is important to identify, in First, the position that holds the wiring inside the computer network; It is divided into three basic components: 1. DCE (data communication equipment). 2. System wiring or cable plant.
3 DTE (data terminal equipment). The basic components of cabling system are the physical link media, carry information from the DCE to the DTE and can be copper or fiber. Even though the basic concept of a wiring system structured is the same, there are cynical different systems: 1. UTP layer3. 2 UTP level 4. 3 UTP nivel5. 4 STP/FTP. 5 Fiber optic. To get all these advantages of structured cabling, it is important to properly combining software and hardware resources.
