A structured cabling system is a detailed system of cabling and associated hardware, which offers a comprehensive infrastructure of telecommunications. Further more we can say a structured system starts at the point where the service provider (SP) ends. This point is the point of differentiation or Network Interface Device (NID).
This infrastructure serves up an extensive range of uses, such as to gives a telephone service or passes on data through a computer network. It does not the device dependent.
For instance, in a telephone system installation, the SP provides one or more service lines as per customer requirements. The SP attaches the service lines at the point of separation.
Why we Need Structured Cabling System?
The process of wiring systems for voice interactions has not changed completely over the last twenty years. Bringing a telephone line to a user`s table is a very simple and well-understood job. But, changes in business purposes require the addition of voice applications with support for integrated services digital network connections, data, graphics, other services over a particular, standardized cabling system. We are beginning to see the initial stages of this new era of combined multimedia in the telecommunications industry.
Various Method of Structured Cabling System:
• The architectural arrangement of the building, like cabling installation in houses
• Connection products and the cable
• The process of the cabling installation
• The design of an already installed system upgrades and retrofits
• Consumer requirements and
• Manufacturer warranties
What are ‘the standards’?
The term “Standard” is to define a process of connecting all types of data equipment and vendor’s voice, above a cabling system which uses a common topology, common media, and common connectors.
Types of Standards:
There are three core cabling standards:
• EIA/TIA 568A – It is the American standard and it was the first to be published in the year of 1991.
• ISO/IEC 11801 – It is the structured cabling systems International standard
• CENELEC EN 50173 -It is the standard of European cabling system.
The system we use to complete and maintain cabling installation and their relatively standard. The standardization of these installations is necessary, as of the need to make sure acceptable system performance from gradually more complex arrangements.
The U.S. cabling industry accepts the American National Standards Institute (ANSI), in combination with TIA or EIA, while the responsible organization for provided that and maintaining their standards and perform within the profession. It has published a sequence of standards to design, install, and retain cabling installations. These help to make sure a proper cabling installation.
The Benefits of Standards:
• Consistency of installation and design
• Conformance to transmission and physical line requirements
• An origin for examining a proposed system growth and other changes
• Standardized documentation
The industry standard for a network installation basically provides a relatively small area, like a structured cabling installation serving for a building, a local area network (LAN). There are also wide area networks (WANs) and metropolitan area networks (MANs).
Structured Cabling Installations Usually Consist of:
Telecommunications closets, vertical and horizontal backbone pathways, entrance facilities; horizontal pathways, equipment rooms, vertical and horizontal, backbone cables, horizontal cables, work area outlets, , consolidation points, cross-connect facilities, transition points, and multi-user telecommunications outlet assemblies (MUTOA).
The entrance facility contains the cabling elements needed to provide a indicate that; connect the outside service facilities to the premises cabling standards. It can include cables, service entrance pathways, circuit protection devices, linking hardware, or transition hardware.
The positions of the entrance facility mainly depend on the type of facility, building architecture, direction of the outside plant cabling, and aesthetic considerations. The four main types of entrance facilities include tunnel, underground, aerial and buried.
