The ANSI/ITA-568 and ISO/IEC 11801 are the two names you need to know because these two are the main structured cabling standards.
What are the different types of cabling?
Cables are classified into 5 types depending upon their purpose as follows:Ribbon Electric Cables. It consists of multiple insulated wires running parallel with one another and is used for transmission of multiple data simultaneously. ... Shielded Cables. ... Twisted Pair Cables. ... Coaxial Cables. ... Fibre Optics Cable.
What is structured network cabling?
Structured cabling is the design and installation of a cabling system that will support multiple hardware uses and be suitable for today's needs and those of the future. With a correctly installed system, current and future requirements can be met, and hardware that is added in the future will be supported.
What is Telecom backbone?
A backbone is a high speed line that connects different parts of a network, usually the different parts of the access network. There are no end users directly connected to a backbone. The end users are connected to the access network. This part of the networkis called the core network.
Why an optical fiber cable is widely used for backbone?
Fiber Optic Backbone Cable Benefits Because of its ability to carry more data than copper, fiber optic cable is frequently used to link switches between telecommunications rooms. In this capacity it acts as a data backbone between rooms. Fiber is also commonly used for longer runs.
Where are the Internet backbones located?
Today, the internet is basically housed in the data centers located in the Washington-area suburb, which is the biggest data center market in the world. “The internet itself is really comprised of these peering points that are housed inside data centers.
Which type of network cable is commonly used in backbone networks and telephone companies?
Fiber-optic cables can carry very large amounts of data and are used extensively by telephone companies and in backbone networks.

Telecommunications Room / Intermediate Distribution Frame (IDF) ... Equipment Rack. ... U. ... Patch Panel.More items...
What is horizontal and vertical cabling?
The horizontal option can secure the cables and keep them separated while within the rack. The vertical will keep everything in place while it goes up or down out of the server rack itself. Coming up with an effective cable management solution for your data center is important.
What is plenum cable?
Plenum rated cable has a special insulation that has low smoke and low flame characteristics. Plenum cable is mandated to be installed in any "air handling" space. For example, most large office buildings use the ceiling to return air to the AC unit.
What is backbone cabling?
Backbone cabling can be described as cabling that delivers interconnection between entrance facilities, equipment rooms, and telecommunication rooms and is usually installed from floor to floor but can also be installed between IT rooms on the same floor.
What is the difference between backbone and horizontal cabling?
While backbone cabling connects entrance facilities, equipment rooms, and telecommunications rooms, horizontal cabling connects telecommunications rooms to individual outlets throughout the building’s floors.
What are the two main methods of structured cabling?
Two indispensable main cabling methods used in structured cabling are horizontal and backbone cabling . These two methods make up some of the most basic components of structured cabling. Although they are different, horizontal and backbone cabling complement each other and are necessary for different types of cabling environments and specifications.
Why is it important to have a qualified cabling contractor?
Since backbone and horizontal cabling are integral components of structured cabling, it’s important to have a qualified cabling contractor design and install your cabling infrastructure. A substandard design and a poor installation job can cause a plethora of inconvenient and expensive problems down the road for your business.
How long is horizontal cable?
It is important to point out that horizontal cabling, regardless of the cable type, must be limited to 90 meters in length between the Work Area Outlet and the termination point in the telecommunications room in order to meet TIA standards .
Can backbone cables be routed underground?
This is relatively straightforward for horizontal cables, but backbone cabling (and inter-building backbone, in particular) can get complicated when the cables are routed underground. It is best to check with your structured cabling contractor to make sure the correct type of cable is being used for the environment in which they are being installed.
Do backbone cables have to be strong?

It must be strong enough to support its own weight and be secured correctly to pass properly between floors. Additionally, both horizontal and backbone cabling must adhere to specific fire-rating specifications, ...
What is fiber optic cable?
Fiber-optic cable is a form of cable that contains one or several glass or plastic fibers in its core and comes in two types: single-mode fiber (SMF) or multimode fiber (MMF). Copper-based cable transmits data via electric signals, and fiber-optic cable transmits data via pulsing light sent from a laser or light-emitting diode (LED). POINTS: 1.
What is STP cable?
STP (shielded twisted pair) cable is a type of copper-based cable containing twisted-wire pairs that are not only individually insulated, but also surrounded by a shielding made of a metallic substance such as foil.
Which device marks where a telecommunications service provider's network ends and the organization's network begins?
In general, the device that marks where a telecommunications service provider's network ends and the organization's network begins is the demarc, or demarcation point. For example, an ISP (Internet service provider) might be responsible for fiber-optic cabling to your building to connect to your LAN.
