Structured Cabling Technologies

What are structure cabling networks

Closed vs. Open structures

Backbone and Horizontal cable

Installed environments

Different types and compare and contrast them

Benefits

Color coding and Wiring sequence

Installation practices

Structured Cabling

Cabling system that allows constant moves and changes to be performed

by on site personnel

Growth and flexibility built into the cabling scheme

Can be either proprietary (closed) or non proprietary (open)

Open System Architecture

Closed systems are proprietary to a particular vendor or system

Open system give greater flexibility by being applications and

vendor independent.

Why open

Facility to run voice, video, data service over same cable.

Investment protects

On site personnel can perform their own shifts and changes, thus

reducing the cost of ownership

Closed vs. Open

Topologies

Topology | Advantages

•Inexpensive to maintain

•Requires less cable

•Does not require extensive training

•Good choice for small networksBus

•Provides equal access for all devices on the ring

•Easier to manage and maintain than bus topology

•Easier to manage and maintain than bus topology

•Handles high volume traffic wellRing

•Easy to install and upgrade

•Central hub makes troubleshooting easy

•Easier to manage and maintain that bus and ring topologiesStar

Topology | disadvantages

•Difficult to isolate malfunctions because of series connections

•When one device fails, all devices fail

•Heavy traffic causes considerable slowdowns and network crashes

Bus

•Difficult to isolate malfunctions

•Expansion of network disrupts services for allRing

•Hub failure causes entire network to go down

•More expensive for cablingStar

Benefits of structured cabling

Greater flexibility

Future-proof solution

Easy, low cost moves and changes

Simpler to manage

No downtime when reconnecting equipments

Independent of protocol and network technologies

Standards & Terminology

Standard organizations

IEEE (Institute of Electrical and Electronics Engineers)

ISO (International Standards Organization)

ANSI/EIA/TIA

UTP Color Coding The purpose of giving color codes to identify

each pair easily.

Both UTP and STP confirms this standard

Wiring sequence The cable color code is the 568B standard on each

end of a straight-through 10/100BaseT cable. If a

crossover cable is needed, use the 568A standard

on one end and 568B on the other end

Use a straight thru cable assembly,568B on both

ends when connecting Hub to Xcvr or NIC Card.

When connecting hub to hub, Xcvr to Xcvr, or NIC

to NIC, the wires must crossover at the opposite

end of the cable assembly,use the 568B on one

end, 568A on the other end
