Time to turn the attention on structured cabling


A structured cabling system can be defined as a comprehensive system or network of cables and associated hardware devices that collectively offer a holistic telecommunication infrastructure and a platform on which an overall hierarchy or system of information is established.
Structured cabling is the foundation of today’s business houses, government organization, and so on. It is also the base of today’s IT network including data voice, alarms or videos. It also defines the transmission patter of the signals through the communication network.

Structured-Cabling

Structured cables are set up and maintained by the contractors who are specialized in this area networking technology. Now, this ensures that the structured cabling system that they set up is absolutely seamless and is best fitted to meet the needs of the businesses. However, the methodology of setting up a structured cabling system is a generic one and is standardized. The standardization the procedure is imperative as it is imperative for the businesses to ensure a universally accepted system performance rather than a complex arrangement, which might put the companies in tight fix.

Even though the methodology of setting up structured cabling system is a generic and standardized one, each and every system develops s a unique identity after it is set up. This ensures that it is absolutely safe and there is no chance of any data pilferage, which is the last thing that a business organization would want to happen. Here are the factors that make each and every structured cabling system is unique.

  • The cables and the connection products used

  • The structure of the architecture of the business premises or the building, where the system is being set up

  • The functionalities of the cabling installation

  • The types of the apparatus and the equipment that the cabling system is expected or intended to support – at present and in the short as well as long term future

  • The configuration of the system that is already installed (if any)

  • Requirements of the customers and the warranties of the manufacturers

Here are the benefits of having a structured cabling system:

  • The communication becomes fast, cost effective as well as reliable. Most importantly, the cabling system is suitable and effective for any type of infrastructure

  • In case the business wants to relocate, the system is flexible enough to be taken down and refitted at the new location with hardly any hassle

  • The system is adaptable o future improvements as well as additions

  • This type of system ensure better and more authentic data encryption, and offers more safety and better and safer storage facilities

Data as well as voice management

Structured cabling helps in simultaneous data as well as voice management and this helps the business to put in the two aspects of communication under one umbrella, thereby reducing the cost and the botheration by a significant aspect.

Talking about them separately, data cabling can defined as setting up of a network of cables that relay or transmit data from one point or place to another. Data cabling helps to set up communication between an effective communication between multiple users and helps analyze the exchanged data at a centralized point.

Voice cabling, on the other hand is the network of cables that helps in setting up of the basic communication, which also includes the land based telephone system, modems and the analog lines.

Structured cables put these separate genres of functionalities within one bracket, thereby setting up a unique data transfer system that indulges in data as well as voice management simultaneously and that too in a seamless and effective way.

This unique feature of this system compels the companies to more and more shift towards structured cabling.

Structured Cabling System (SCS) is a set of cabling and connectivity products that integrates various data, voice, video, and various other networking management systems of a building. SCS consists of a number of standardized elements, open architecture, and standard connection interfaces. SCS is a complete system of cabling and related hardware, which provides a comprehensive networking system. This has wide range of uses, such as providing business phone systems or transmitting data over a computer network. The structured cabling system starts at the particular point where the service provider terminates. This point is referred to as the point of demarcation or Network Interface Device.


There are generally six major structured cabling system components. These are building entrance, equipment room, telecommunications closet, backbone cabling, horizontal cabling and work area. These are also known as subsystems.

 

Building Entrance: Building entrance requirement specification is for the point at which the cable enters a building. The specification includes recommendation for type of connection and surge protection devices. Entrance facility includes cabling, connecting hardware, network demarcation point or points, protection devices and other equipment which connect to the access provider and/or network cable. This also includes connection between the inside of the building and the outside.

Equipment Room: Networking equipment rooms generally house equipment of higher complexity compared to telecommunication closets. Almost all the functions of a telecommunications closet are provided by an equipment room. It may be any secure storage area in which the cables, communication racks, servers, switches, routers and other expensive hardware devices are located. An equipment room must always be locked in order to prevent theft of equipment as well as data security and also restrict unauthorized access.

Backbone Cabling: Backbone cabling is one which runs vertically between the floors or between the equipment rooms. This provides interconnection between the building entrance sites, equipment rooms, including Cat5 or Cat6 cables and terminators. This includes vertical connection between floors, cables between an equipment room and building cable entrance facilities and cables between buildings. The term backbone depicts the cable handling major network traffic. There are two types of backbone cabling. One is the inter building and other is the intra building.

 

Telecommunications Closet:  Telecommunications closet is that area inside a building which mounts the telecommunications cabling system. It includes mechanical terminations and cross connects for horizontal as well as backbone cabling system. It may also include the MC or IC for various portions of backbone cabling system. Telecommunications closet also provides a controlled environment to the telecommunication equipment and connecting hardware. Using Telecommunications closet is for specific implementation.

Horizontal cabling: Horizontal cabling is the physical media which runs at the work station outlet to the termination point in the equipment room.

Horizontal cabling system extends from work area telecommunications outlet to the telecommunications closet and includes horizontal cable, jumpers, mechanical terminations and patch cords which are located in TR or TE. This may also incorporate multi user telecommunications outlet assemblies and consolidation points. Often, horizontal cables are routed directly from the closet to the work station without any cable junctures, splices or taps. This reduces the chance of faulty connections and electrical noise to a great extent.

Work area: The work area component extends from the telecommunications outlet to the work station equipment. Work area wiring is designed in such a way that it is relatively simple so that interconnection, addition and changes can be managed easily. At least two telecommunications outlets have to be provided for each work area. The work area includes the following components:
a.Station equipments, data terminals, computers, telephones etc.
b.Patch chords, PC adapters, fibre jumpers, etc
