Structured cabling
The Structured cabling, also known as Generic Cabling ( UGV ) is a unified structure plan for cabling for different services ( voice or data) represents a structured cabling is part of the technical infrastructure of a property and is divided into primary, secondary and tertiary education. For Structured Cabling there is the European Committee for Electrotechnical Standardization ( CENELEC), the European standard EN 50173-1 for Generic Cabling Systems (November 2002), which is published as DIN standard. International Related to the Standard ISO / IEC 11801:2002 is significant. Often, the cabling according to the North American standard TIA / EIA 568 are built.

Areas
Primary area
The primary region is the wiring of the building a site with each other and is also referred to as campus wiring or premises wiring. The primary area includes the location of the manifold to the outer link of the site, the building distributor and the cables between the building distributors (primary cable) of a LAN. In the primary range long distances, high data transfer rates as well as a small number of connection points are determinative. Here, the optical fiber as the transmission medium due to their low loss, high bandwidth (and thus saving multicore copper cables ) and the electromagnetic insensitivity is particularly suitable. In addition, a galvanic separation takes place, and it can be dispensed with an elaborate potential equalization between the buildings. Is also practiced a connection over the phone line with VDSL, provided a corresponding circuit is possible. Cable types used: fiber, copper cable.
Maximum lengths:
- FO: 1500 m from the campus distributor to the building distributor
- VDSL: Up to 900 m: 52 Mbit / s falling to 26 Mbit / s; At 2 km from ADSL transmission rates
Secondary area
The secondary sector is the vertical floor cabling, so the wiring of the floors of a building with each other and is also known as the riser cabling or as building wiring. The secondary sector includes the building distributor and the cables from the building distributor ( server space ) on each floor distributors ( secondary cable) lead. Types of cable used ( according to DIN ): Fiber Optic.
Maximum length: 500 m
Tertiary
Tertiary education is the horizontal floor wiring, so the wiring harness inside the floors of a building and is also known as floor cabling. Tertiary education comprises the floor distributor with cables to the junction box (tertiary cable) and the Sockets Cable species themselves used: twisted pair cable with fiber to the desk fiber optic cables.
Maximum length: 100 meters for twisted-pair, with 90 meter fixed wiring ( BASIC -Link, as an installation cable called ) and 10 meters (2 × 5 meters) provided loose wiring ( CHANNEL link, also known as a patch or patch cord ) are. For fiber optic connections are cable lengths depending on the type of the cable up to several kilometers possible.
Elements
Cabinets
The cabinets are the cabinets for building and floor distributors. Cabinets and accommodated therein patch panels are designed in most installations in 19 -inch system technology. In the wiring closets also elements of active network equipment (such as switches, hubs) and telephone systems are often housed.
Patch Panel
Patch panels for copper and fiber optic cables are different sized distribution panels. Set depending on the required amount corresponding number of ports available.
Patch Cable
Patch cable for the marshalling between patch panels. Here specially shielded CAT6 or CAT7 patch cables are often used.
Outlets
Outlets (german telecommunication outlets ) to category 6 with RJ45 and from category 7 GG45 or Tera endpoint.
Cable
- Primary cable,
- Secondary cable and
- Tertiary cable,
Respectively as copper or fiber cable.
