What is the term used that defines network cabling in the work area and between telecommunications closets and equipment rooms?

• What term is used for the cabling that runs from the telecommunications room to the PC?
• What specialized equipment will he use to connect the endpoint of a cable run to a patch panel?
• Why is it called structured cabling?
• What type of twisted pair cabling would work best in horizontal cables?
• What is considered structured cabling?

Network cabling that interconnects telecommunications closets (IDFs) and equipment rooms (MDFs). This cabling (also called “vertical cabling”) runs between floors or wings of a building and between buildings to carry network traffic destined for devices outside the work area.

What types of coax cabling have been used in computer networking?

Two main types of coaxial cable are used in computer networking: thinnet (RG-58) and thicknet (RG-8 or RG-11). Thinnet cable can transmit 10Mbps up to 185 meters. Wire segments of thinnet are connected with BNC connectors. Thinnet coaxial cables are commonly used for 10Base2 Ethernet networks.

What specialized equipment will he use to connect the endpoint of a cable run to a patch panel?

The main patch panel. For telephones, the cabling might connect to a special CPE called a multiplexer, and on the LAN side, almost certainly to a powerful switch. The switch usually connects to a patch panel. Patch panel, in turn, connects to every telecommunication room in the building.

What is the set of standards established by the EIA TIA regarding network cabling called?

ANSI/TIA-568 was developed through the efforts of more than 60 contributing organizations including manufacturers, end-users, and consultants. Work on the standard began with the Electronic Industries Alliance (EIA), to define standards for telecommunications cabling systems.

Why is it called structured cabling?

In telecommunications, structured cabling is building or campus cabling infrastructure that consists of a number of standardized smaller elements (hence structured) called subsystems.

What is the structured cabling system?

A Structured Cabling System is a set of cabling and connectivity products that integrates the voice, data, video, and various management systems of a building (such as security alarms, security access, energy systems, etc.).

What type of twisted pair cabling would work best in horizontal cables?

Cables for Horizontal Cabling Four-pair 100-ohm unshielded twisted-pair (UTP) cable (Cat5e cable, Cat 6 cable or Cat6a cable) is usually recommended for voice and fiber optic cable (two-fiber 62.5/125-micron or 50/125-micron multimode cable, or higher fiber count ) is commonly used for data transmission.

Which are the two twisted pair cables types available?

There are two main types of twisted pair cables, unshielded twisted pair (UTP), and shielded twisted pair (STP), which contains each pair of wires within an aluminium foil shield for further isolation.

What is considered structured cabling?

In telecommunications, structured cabling is building or campus cabling infrastructure that consists of a number of standardized smaller elements (hence structured) called subsystems. Structured cabling components include twisted pair and optical cabling, patch panels and patch cables.

What is cabling structure of LAN called?

:: Vertical Cabling (Backbone Cabling) Telecom rooms on each floor are then connected together by backbone cabling (also called vertical cabling for floor to floor connections). These backbone cablings typically are done from floor to floor to floor.

Structured Cabling… is defined as building or campus telecommunications cabling infrastructure that consists of a number of standardized smaller elements (structured).

Structured cabling installations typically include: entrance facilities, vertical and horizontal backbone pathways, vertical and horizontal backbone cables, horizontal pathways, horizontal cables, work area outlets, equipment rooms, telecommunications closets, cross-connect facilities, & multi-user telecommunications outlet assemblies (MUTOA).

Structured cabling begins at the demarcation point of a building. The demarcation point, or demarc, is the point in a building where a service provider delivers phone lines and data circuits. From there it is up to the customer to design a structured cabling system that then takes those services, connects them to their network hardware, and ultimately deliver phone lines and data connection points for computers at employees’ desks. In larger multi-story buildings, telecommunications closets are normally stacked on top of each other on each floor of a building. Carrier services can be extended into each of these telecommunications closets, and then extended into each tenant’s suite on their respective floor.

A facility typically will have a Main Distribution Frame, or MDF. This MDF houses the network equipment which takes local devices and equipment (inside plant), and connects them to cables and subscriber carrier equipment for connections beyond the local facility (outside plant). The services that are delivered at the demarcation point are extended to this MDF for connections inside the building. The MDF will typically have data racks that include network routers, switches, modems as well patch panels for terminations of cabling that is ran throughout the building. Using a ladder tray is best practice for routing cabling to data racks inside the MDF from the backbone cable pathways typically in the ceiling.

Larger buildings may require an Intermediate Distribution Frame, or an IDF. An IDF is simply a cable rack that interconnects and manages the telecommunications wiring between an MDF and workstation devices. An IDF connects users to the MDF; In contrast a MDF connects users to carrier services. Depending on the function of a data cable, the limit in which a data cable can be pulled is 100 meters. This means that if there is an endpoint such as a workstation device that is farther than 100 meters from the MDF, an IDF will need to be installed.

Horizontal and vertical backbone pathways are used to extend cabling from the demarcation point, to the MDF. Backbone pathways are also used to extend cabling from a MDF to an IDF. These backbone pathways include a type of cable support which houses the cabling infrastructure in an organized manner. The cabling support is installed along walls, or mounted directly to the structure of a building. Support points are typically installed every 4-6’ on the backbone pathways to suspend cable without having too much droop, or sag between support points. Keeping support points at this distance limits the droop between supports, as well as limits unnecessary force from gravity as the sagging cables pull on the nearest support point. There are many different choices in support systems, just as there are many different designs of buildings and their structure. The amount of cabling needed for endpoint devices, as well as the design of a building can determine which type of cabling support will work best for that particular environment. A properly designed cabling system will be adequately labeled at each endpoint for troubleshooting purposes as well as ease in Moves, Adds, or Changes. Depending on what type of communication cabling is used, (ie: Fiber Optic/Cat5e/Cat6), bend radiuses as well as distance from electrical components must be taken into consideration. The local wiring/electrical codes of the area must also be considered when designing structured cabling systems.

Structured cabling is simply a term used in a properly designed way of getting cabling from carrier services to endpoint users. While there are several components in a businesses’ network topology, a properly designed structured cabling system is imperative for reliable data transmission.
