Lesson 1-3: Cabling
At a Glance
The physical pathway used to connect two or more computers together as a
network includes the transmission media. The quality of the network system
is dependent on its transmission media. The most common forms of electrical
and electronic transmission are solid and composite wire cables. There are
several types of cable, including coaxial, unshielded twisted-pair and fiber
optic. Each type adheres to standards set by the Institute of Electrical and
Electronics Engineers (IEEE).
The Telecommunications Industry Association (TIA) and the Electronic
Industries Association (EIA) standards govern all aspects of cable installation,
such as regulations on cabling distances and connector configurations.
In choosing cabling for a network, there are several factors to consider: cost,
expansion capabilities, bandwidth, signal attenuation, and EMI (Electro-
Magnetic Interference). Each type of cable has different specifications that
affect these factors, and each organization has different needs. Considering
cable system factors is very important for building a network system that
meets an organization’s needs.
What You Will Learn
After completing this lesson, you will be able to:
• Describe three different types of cable and their structural components.
• Demonstrate an understanding of specifications and attributes for coaxial,
UTP, and fiber optic cable and how these factors guide decision-making in
building networks.
• Identify and describe Ethernet cable crimping using proper TIA/EIA 568
wiring sequences.
• Crimp and test Ethernet Category 5 cable and discuss cabling quality
issues.

Tech Talk
• BandwidthBandwidth represents how much information can be sent at
one time over a specific cable type, or the measure of information capacity
of transmission over a cable. Bandwidth is the difference between the
highest and lowest frequencies of the transmission, measured in hertz.
Bandwidth is a factor used to evaluate cable.
• BNCThe “British Naval Connector” is the connector used with coaxial
cables.
• ExpansionExpansion is the ability to increase the size of a network after
the initial installation. It is a factor used to evaluate cable.
• Fiber Optic CableFiber optic cable uses light to transmit information
across a network. The core of the cable is made of glass, which is protected
by a layer of gel or plastic. A plastic cover surrounds the entire cable.
• Hertz (Hz)Hertz is the unit of frequency measurement, which is equal to
one cycle per second (for example, one waveform per second). Computers
and related devices are often measured in kilohertz (kHz=1,000 Hz),
megahertz (MHz=1,000 kHz), gigahertz (GHz= 1,000 MHz).
• EMI (Electro-Magnetic Interference)The interference of electrical
signals across a cable by outside electrical or magnetic devices. It is a
factor that is used to evaluate cable.
• RJ-11A registered jack 11 is a telephone connector used on modern
telephone lines.
• RJ-45A registered jack 45 is an eight-wire connector used to connect
computers to category 5 unshielded twisted pair cables in a network.
• Signal AttenuationSignal attenuation is a factor used to evaluate cable
that relates to how long a signal can travel across a cable before the signal
becomes too weak to be recognized in a network.
• Thin Coaxial CableThin coaxial cable is often referred to as ThinNet.
It consists of a copper wire surrounded first by a layer of plastic, then a
layer of metal mesh and a final layer of protective plastic. It is used for
peer-to-peer networking.

ST0025803A 65
• Transmission MediaTransmission media is the physical pathway used
to connect two or more computers together as a network and includes air
and space in addition to cable.
• Unshielded Twisted-Pair Cable (UTP)UTP is network cable that
consists of up to 4 pairs of wires. Each pair is twisted around each other at
a different rate and the entire cable is encased in a protective plastic
covering.
Decision Factors in Choosing Cable for a Network
• The bandwidth represents how much information can be transferred over
the cable at one time. The greater the cable’s bandwidth the faster the
information is passed over the network.
• The further information must travel over a cable the more the electrical
strength weakens. This is referred to as signal attenuation. Each type of
cable can transmit information up to a specific distance without special
equipment to help boost the electrical signal.
• EMI (Electro-Magnetic Interference) comes from electrical signals emitted
by equipment such as photocopiers, fluorescent lights, and electrical wiring
that may disrupt the transmission of information across a network. Some
cables are better designed to block out EMI (Electro-Magnetic Interference)
than others are.
• Organizations may not always be able to build the largest network needed,
or their office may grow over time and need more computers added to their
network. The ease of installation and need for additional equipment affect
the expansion capability of the cable.
• The cost of the cable used to build a network is very important. Most
organizations have limited funds and seek to build the optimum network.

Cables
Solid wire and cable are the oldest forms of electronic transmission media.
This lesson covers three basic types, still in use in building networks, coaxial,
unshielded twisted-pair, and fiber optic. Thin coaxial cable has a core of copper
wire and is primarily used for peer-to-peer LANs due to its low bandwidth and
problems with EMI (Electro-Magnetic Interference). Unshielded twisted-pair
cable has twisted pairs of wires as the core and is divided into five categories,
with category 5 used most commonly for building LANs. Fiber optic cable has a
core made of glass and uses light pulses to transmit information across a
network.
Thin Coaxial Cable
Early networks used coaxial cable to connect computers together. Many LANs
were built with coaxial cable. It is often referred to as ThinNet.
Coaxial cable has:
• A core of copper wire surrounded by a layer of plastic.
• A layer of metal mesh.
• An outer protective plastic insulation sheath.

ST0025803A 67
Coaxial cable is terminated with British Naval Connectors (BNC).
Terminators used with BNC/thin coaxial cabling must be 50-ohm terminators.

Expansion
Issues
Expansion into multiple rooms is difficult since
each computer must be connected directly on to
the cable in a chain fashion, often referred to as a
bus topology. The cable is thicker and less
flexible than unshielded twisted-pair cable. This
cable is best used for peer-to-peer networking in
a small workgroup LAN.
Relative Cost Low.

Lesson 1-3: Cabling
Unshielded Twisted-Pair Cable
Unshielded twisted-pair cable is separated into five categories designated by
the TIA/EIA 568-A standard.
• Category 1 is telephone cable.
• Category 2 was used for token ring networks and is not recommended for
Ethernet networks.
• Categories 3 and 4 can be used with Ethernet networks, but suffer more
from EMI than category 5. Category 3 cables typically have twotwists per
foot. Category 4 cables have more twists per foot, but less than Category 5
cables. The twisting of the wires in cables is to help prevent EMI (Electro-
Magnetic Interference).
• Category 5 cable is primarily used in LANs. The most typical connector
used with UTP is a RJ-45, which resembles a large telephone connector
(RJ-11). This cable has a very high twist rate per foot.

other electrical signals.
Signal
Attenuation
Maximum distance is 100 meters.
Expansion
Issues
The cable is thin and flexible, which makes
installation easy. Expansion is easy, but
specialized network equipment is needed to boost
the signal. This equipment increases the cost of
expansion.
This cable is used as a standard today in all
Ethernet LANs.
Relative Cost Least expensive.
Within unshielded twisted-pair (UTP) cable there are typically 2 to 8 wires, 1
to 4 pairs. Each pair is twisted around each other at a different rate, which
reduces EMI (Electro-Magnetic Interference) between the pairs and other
electrical signals. Each pair is color-coded, according to standards, and the
entire cable is inside a protective plastic insulation sheath.
In Category 5 UTP, there are usually 4 pairs of wires, with one wire of solid
color and one of white with the same color stripe in each pair:
• 1 orange pair
• 1 brown pair
• 1 blue pair
• 1 green pair

Lesson 1-3: Cabling
The TIA/EIA 568 standard has two wiring sequences, T568A and T568B. The
sequence of the wires dictates how the wires are terminated on the
RJ-45 connector. Either sequence may be used to set up a network. Once a
wiring sequence has been chosen, using the same sequence throughout the
entire network is necessary. Data networks usually use the TIA/EIA 568B
standard. The wires must be correctly paired together for the entire length of
the cable to ensure signal quality.
TIA/EIA 568A Wiring Sequence
In both the 568A and 568B sequences, pair 1 is always designated as the blue
wires and pair 4 is always the brown wires. Pair 1 is always assigned to pins 4
and 5 in the connector. The solid blue wire connects to pin 4, as a ring (R) wire,
and the white wire of the blue pair connects to pin 5, as a tip (T) wire. Pair 4 is
always assigned to pins 7 and 8 on the connector. The white wire of the brown
pair connects to pin 7, as the tip wire, and the brown wire connects to pin 8, as
the ring wire. The terms tip and ring are old telephony terms used to
designate the tip (Tipping the telephone handset off the cradle to transmit a
signal that a phone number is about to be dialed) and ring (The response heard
on the receiving end of the handset once the number is dialed and the phone is
ringing on the other end).
The blue and brown pairs may not be used if the network system is set to use
up to 10 Mbps bandwidth. In this instance, the blue pair may be used for voice
transmission (telephone) and the brown pair dedicated to other network
functions. The orange and green pairs, pin positions #1, 2, 3, and 6, are used
for Ethernet transmitting (pins 1 and 2) and receiving (pins 3 and 6).

Fiber-Optic Cable
Fiber optic cable uses light pulses rather than electrical signals to transmit
information across a network. The cable may be used over many miles because
there is no electrical EMI (Electro-Magnetic Interference) and the bandwidth is
very high. Fiber optic cable is usually used for the backbone of a network.
Since glass and plastic cores can be cracked or broken, installation requires
care. Special monitoring equipment is required to locate a break in the fiber
optic cable.

main cable of LANs, WANs, and MANs in
Enterprise networks.

Try It Out
Crimping Cable
In this activity, you will cut, strip, and crimp a piece of category 5 unshielded
twisted pair cable and attach it to a RJ-45 connector. Once you complete this
task, you will test your cable to see if your connections function properly.
Materials Needed
• Category 5 Unshielded Twisted Pair (UTP) Cable
• Crimping Tool (model 24-4680P, or equivalent)
• Two (2) RJ-45 Connectors
• Cable Tester (Brand and model in equipment package, or equivalent)
Procedure:
Keep a record of this activity as an item for your portfolio. As you go through
each of the steps, record any problems you encountered, and any observations
you think are important. Your ability to discuss problems and issues of
network cabling will be of interest to industry employers.
1. Look at the illustration below and compare it with your crimping tool. The
illustrated tool has a stripping blade, a cutting blade, an RJ-45 connector
insert for eight wire category 5 UTP, and an RJ-11 connector insert used for
six wire telephone cable. Your crimping tool may not have all these
features. In that case, you may need to use more than one tool, for
example, a separate wire stripper and/or cutter.

ST0025803A 75
2. Cut the category 5 UTP cable to a length specified by your instructor. The
ends must be cut squarely, not diagonally. To cut the cable, insert it
between the cutting blades and squeeze the crimper handles firmly to close
the blades.
Crimping Tool – Stripping/Cutting Blades

3. To strip the sheathing, insert the end of the cable between the stripper
blade with the cable end against the backstop. The stop prevents stripping
too much insulation from the cable. Squeeze the blades closed with a gentle,
continuous pressure. Too much pressure will cut the wires! Rotate the cable
to cut the plastic insulation sheath. Remove the cable from the stripper
blades and peel off the short section of plastic sheath.
4. Arrange exposed wires in pairs. If you don’t have eight wires (four pairs of
two); you may have cut through one or more wires when you stripped off
the insulation sheath. Cut off one inch and repeat the stripping if you don’t
have eight wires.
5. Closely examine the RJ-45 connector. On one side you will see the plastic
locking clip, and on the other, eight metallic pins. You will notice that the
pins are raised slightly above the surface.
6. Carefully insert the eight wires into the connector in the order specified by
the T568B wire sequence (see the illustration below).

7. Each wiremust fit into one of the eight separate slots beneath the pins. To
make this task easier, separate the wires slightly. When you insert the
cable, each wire will slide into a separate slot.
8. Push the cable in with a steady firm pressure until all of the wires are fully
inserted into the connector. The ends of the wires must make direct contact
with the metal pins at the tip of the connector.
9. Insert the connector assembly into the RJ-45 crimping slot. Align the metal
connector contacts with the crimper teeth. Squeeze the handles to crimp.
Insert the RJ-45 into the Crimper
RJ-45 Crimper

ST0025803A 77
10. Check the metal pins to see if each individual wire is crimped. The way to
be sure is to look at the metal pins. You will notice that they are no longer
raised as high on the connector. If they remained in the same position,
realign the connector and crimp again. If the plastic cracked, make a new
cable cut and try again.
11. Record the color sequence of the wires on your portfolio record sheet as
shown in the table below. Hold the connector with the metal contact pins
facing you and the plastic locking clip facing away. Starting from either
side, record the colors of the wires in the table below. It is very important
to compare the order you placed the wires to the T568B wiring sequence.

Troubleshooting Cable
Materials Needed
• Student-crimped Category 5 UTP Cable with RJ-45 Connectors
• Microscanner
During the Try It Out activity, you created your own category 5 cable with RJ-
45 connectors. Some of your first attempts at creating a working cable may not
work. Cable making proficiency comes with attention to detail, care, and
practice. In this activity, you are going to troubleshoot potential problems with
cables using a microscanner. First, you will check existing cables found in your
lab and then you will check the patch cable you made. Patch cable is a common
term used for the short wire segments used to connect computer devices to the
main cable connection.
1. Test existing networking cable. Insert one end of the cable connector of an
existing cable (not the one you made) into the “main” port of the
microscanner as shown below. The other end of your cable should be
connected to the RJ-45 port of a computer workstation.
