Structured office cabling

A structured cabling system is a complete system of cabling and associated hardware, which provides a comprehensive telecommunications infrastructure. This infrastructure serves a wide range of uses, such as to provide telephone service or transmit data through a computer network. It should not be device dependent.
We further define a structured cabling system in terms of ownership. The structured cabling system begins at the point where the service provider (SP) terminates. This point is the point of demarcation (demarc) or Network Interface Device (NID).
For example, in a telephone system installation, the SP furnishes one or more service lines (per customer requirements). The SP connects the service lines at the point of demarcation.
Structured cabling” may lead you to believe that the system is only made of cables in your data center, but that’s not quite the case. A structured cabling system actually runs throughout a building or across a campus, with different points and dedicated areas
Besides cables, structured cabling solutions can include racks, network cabinets, hardware ports and more. All of these smaller pieces work together as part of the overall system. The standardised elements that make up structured cabling are called “subsystems.” These subsystems are typically located across a building, so it’s important to know where they’ll be in your business location.
