Structured cabling

In telecommunications, Structured cabling is the design and installation of a complete, standards-compliant telecommunications cabling infrastructure for building, platform, factory or campus cabling infrastructure. It is a systematic and organized approach that involves using a set of standardized, smaller elements (hence structured) called subsystems. To create a single, flexible, and scalable infrastructure that supports multiple uses and changes. Unlike point-to-point wiring systems, where each piece of hardware has dedicated cabling, a structured cabling system uses a hierarchy of cabling to avoid direct cross connects. The design and performance characteristics of structured cabling are governed by industry standards, such as ANSI/TIA-568, EN 50173, and ISO/IEC 11801 to ensure interoperability and predictable performance. Structured cabling components include twisted pair, optical cabling, patch panels, patch cables and equipment rooms.

With a correctly installed system, current and future requirements can be met, and hardware that is added in the future will be supported. In the OSI model structured cabling is a form of physical/transmission media. ==Subsystems== Structured cabling consists of six subsystems: Entrance facilities is the point where the telephone company network ends and connects with the on-premises wiring belonging to the customer. Equipment rooms house equipment and wiring consolidation points that serve the users inside the building or campus. Backbone cabling is the inter-building and intra-building cable connections in structured cabling between entrance facilities, equipment rooms and telecommunications closets. Backbone cabling consists of the transmission media, main and intermediate cross-connects and terminations at these locations. This system is mostly used in data centers. Horizontal cabling wiring can be standard inside wiring (IW) or plenum cabling and connects telecommunications rooms to individual outlets or work areas on the floor, usually through the wireways, conduits or ceiling spaces of each floor. A horizontal cross-connect is where the horizontal cabling connects to a patch panel or punch-down block, which is connected by backbone cabling to the main distribution facility. Telecommunications rooms or telecommunications enclosure connects between the backbone cabling and horizontal cabling. Work-area components connect end-user equipment to outlets of the horizontal cabling system. ==Standards== Network cabling standards are used internationally and are published by ISO/IEC, CENELEC and the Telecommunications Industry Association (TIA). Most European countries use CENELEC, International Electrotechnical Commission (IEC) or International Organization for Standardization (ISO) standards. The main CENELEC document is EN50173, which introduces contextual links to the full suite of CENELEC documents. ISO/IEC 11801 heads the ISO/IEC documentation. In the US, the Telecommunications Industry Association issue the ANSI/TIA-568 standards for telecommunications cabling in commercial premises. ==See also== 110 block American National Standards Institute (ANSI) Registered jack, a set of standards for telecommunications cabling termination (including RJ11, RJ15, and RJ45) Telecommunication cabling ==Notes== ==References== ==External links== Fiber Optics Tech Consortium (FOTC)
