Coaxial Cable
Overview:
 Was the foundation of Ethernet networks in 1970s – replaced by newer
twisted pair and fiber cable
 Has a single or multiple copper strands at its center – protected by PVC
or Teflon insulation
 Protected and grounded via metallic shield (“braiding”)
 Protected from physical damage by a layer of dielectric insulator
(“sheath”) on the outside
 Allows relatively long segments and highly resistant to noise – more
expensive and less convenient to handle
Assiut STEM School

Coaxial Cable
Overview (continued):
Assiut STEM School

Coaxial Cable
Overview (continued):
 Defined by Radio Guide (RG) specifications – with few most
common types in use
 Classify the cores according to American Wire Gauge (AWG)
numbers – the smaller is the diameter, the larger is the AWG
number
 Differ by materials used for the core and for shielding, the
core’s diameter, impedance, attenuation, data rates, and
terminators used

coaxial cabling that's often used
to connect a Video Recorder to
a TV.

Coaxial Cable Termination
Overview:
 Two common types – F-type and BNC
F-Connector:
 Suitable for cables with a solid metal core –
becomes the pin in the center of the connector
(used in RG-6)
 Mounted on a cable by crimping or compression –
both male and female connectors are threaded
and screw together like a nut and bolt assembly

Bayonet Neill-Concelman (BNC) Connector:
 Mounted on a cable by crimping, compression, or
twisting – connects to another BNC connector via a
turning and locking mechanism (“bayonet coupling”)
 Male connector uses its own conducting pin – not the
core of the cable like F-type ones
 Commonly used with RG-59 cable

What is a Decibel?
A decibel (dB) is a unit used to express relative
differences in signal strength. A decibel is expressed as
the base 10 logarithm of the ratio of the power of two
signals, as shown here:
dB = 10 x Log10 (P1/P2)
where Log10 is the base 10 logarithm, and P1
and P2 are the powers to be compared.

What is a Decibel?
Note: Log10 is different from the Neparian
Logarithm (Ln or LN) base e logarithm.
You can also express signal amplitude in dB.
Power is proportional to the square of the
amplitude of a signal. Therefore, dB is expressed
as: dB = 20 x Log10 (V1/V2)
where V1 and V2 are the amplitudes to be
compared.
dBm = dB milliwatt = 10 x Log10 (Power in mW / 1 mW)
10 mW = 10 mW/1mW=10 = 10 dBm = 10 x Log10 (10)

cable cannot exceed 325 feet or 100 m
in length.
Cat5e cable, with a standard
connector, known as an RJ-45
connector.

10BaseT cabling is available in different grades or categories. Some grades,
or "cats", are required for Fast Ethernet networks, while others are
perfectly
acceptable for standard 10Mbps networks--and less expensive, too. All new
networks use a minimum of standard unshielded twisted-pair (UTP)
Category 5e 10BaseT cabling because it offers a performance advantage
over lower grades.

The baud rate is the rate at which
information is transferred in a
communication channel. In the serial
port context, "9600 baud" means that
the serial port is capable of transferring
a maximum of 9600 bits per second.

The following summarizes the features of UTP cable:
- Speed and throughput—10 to 1000 Mbps - Average cost per node—Least expensive
- Media and connector size—Small - Maximum cable length—100 m (short)
Commonly used types of UTP cabling are as follows:
• Category 1—Used for telephone communications. Not suitable for transmitting data.
• Cat 2—Capable of transmitting data at speeds up to 4 megabits per second (Mbps).
• Category 3—Used in 10BASE-T networks. Can transmit data at speeds up to 10 Mbps.
• Category 4—Used in Token Ring networks. Can transmit data at speeds up to 16 Mbps.
• Category 5—Can transmit data at speeds up to 100 Mbps.
• Cat 5e —Used in networks running at speeds up to 1000 Mbps or 1 Gbps.
• Category 6—Typically, Category 6 cable consists of four pairs of 24 American Wire
Gauge (AWG) copper wires. Category 6 cable is currently the fastest standard for UTP ,
with Cat6 STP data can travel with 10 Gbps . Eng. & Educator Osama Ghandour
Assiut STEM School

Shielded Twisted-Pair Cable
(STP) cable combines the techniques of shielding,
cancellation, and wire twisting. Each pair of wires is
wrapped in a metallic foil . The four pairs of wires then
are wrapped in an overall metallic braid or foil, usually
150-ohm cable. As specified for use in Ethernet
network installations, STP reduces electrical noise both
within the cable (pair-to-pair coupling, or crosstalk)
and from outside the cable (EMI and RFI).Eng. & Educator Osama Ghandour
Assiut STEM School

Although STPprevents interference better than
UTP, it is more expensive and difficult to install.
In addition, the metallic shielding must be grounded
at both ends. If it is improperly grounded, the shield
acts like an antenna and picks up unwanted signals.
Because of its cost and difficulty with termination,
STP is rarely used in Ethernet networks. STP is
primarily used in Europe. Eng. & Educator Osama Ghandour

team work

The following summarizes the features of STP cable:
- Speed —10 to 100 Mbps - Average cost Moderately expensive
- Media and connector size—Medium to large
• Maximum cable length—100 m (short)
When comparing UTP and STP, keep the following points in mind:
• The speed of both types of cable is usually satisfactory for LAN
• These are the least-expensive media for data communication. UTP
is less expensive than STP.
• Because most buildings are already wired with UTP, many
transmission standards are adapted to use it, to avoid costly
rewiring with an alternative cable type.

Fiber Optic Cable
Layered Structure:
 Inner core – glass or plastic fibers at the center that carry
laser pulses or an LED light used for data transmission
 Cladding – a layer of plastic or glass around the fibers
that reflects the light back to the core
 Plastic buffer – an opaque layer that protects the
cladding and the core and absorbs any light that escapes
 Strands of Kevlar – a polymeric fiber that surrounds the
plastic buffer and prevents stretching and damaging
 Plastic sheath – providing the overall cable protection

Fiber Optic Cable
Single-Mode Fiber (SMF):
 Uses narrow core – less than 10 microns in diameter
 Propagates light without reflections – causes no
dispersion and no significant energy loss
 Provides the highest bandwidth of all media and
allows the longest distance without requiring
repeaters
 Allows 60 km (37 mi) long segments at 10 Gbps
 Good for connecting large networks together
 The most expensive networking medium
 Suitable for WANs Eng. & Educator Osama Ghandour

Assiut STEM School

Multi-Mode Fiber (MMF):
 Uses wider core – from 50 to 115 microns in diameter,
with 62.5 microns being most common size
 Multiple laser or LED pulses are sent over the fiber at
different angles
 Allows 300 m (910 ft) long segments at 10 Gbps, 550 m
(1670 ft) at 1 Gbps, and 2 km (6060 ft) at 100 Mbps
 Used for connecting network devices to a backbone
 Suitable for both LANs and WANs

SMF vs. MMF:
Fiber Optic Cable
Assiut STEM School

MMF vs. Copper, Advantages:
 Allows longest distances without requiring repeaters
 Much more resistant to noise
 Very secure – tapping into light transmissions isn’t
easy
MMF vs. Copper, Disadvantages:
 Installation and field repairs are much more complex
for MMF (requires special equipment)
 Much more expensive
 MMF is used to provide much higher throughput – not
anymore (CAT7 TP cable – up to 10 Gbps)
Fiber Optic Cable
Assiut STEM School

Fiber Optic Cable
Characteristics:
 Highest throughput – no resistance allows achieving 100
Gbps per channel and reduces errors
 Highest cost – most expensive medium, NICs, and hubs, plus
the highest installation costs – not practical for small
networks
 Best EMI and noise immunity – no current used
 Size and scalability – segment length is limited by degradation
of the signal (“optical loss”), with typical values from 150 to
40,000 meters (455 to 121,200 ft)
 Imperfections at connection points affect segment length

Fiber Optic Cable
Connectors:
 Ten different types exist, with four being being most common –
Straight Tip (ST), Standard Connector (SC), Local Connector (LC),
and Mechanical Transfer Registered Jack (MT-RJ)
 All can be used for both SMF and MMF
 ST and SC are used on older networks
 LC and MT-RJ are smaller in size – allow higher density at
termination points, used in newer networks
 MT-RJ connector contains two strands of fiber in a short
protective tube (“ferrule”), allowing full-duplex mode

Single Mode Fiber Optic Cable
has a small diametral core that allows only
one mode of light to propagate. Because of
this, the number of light reflections
created as the light passes through the
core decreases, lowering attenuation and
creating the ability for the signal to travel
further. This application is typically used
in long distance, higher bandwidth runs
by Telcos, CATV companies, and Colleges
and Universities , Ex 1Gps for length of
1000m.
usually 9/125 in construction. This means
that the core to cladding diameter ratio is
9 microns to 125 microns.
Multimode Fiber Optic Cable
usually 62.5/125 in construction.
This means that the core to cladding
diameter ratio is 62.5 microns to 125
microns.
has a large diametral core that allows multiple
modes of light in different angeles to propagate.
So , the number of light reflections created as the
light passes through the core increases, creating
the ability for more data to pass through at a
given time. Because of the high dispersion and
attenuation rate with this type of fiber, the
quality of the signal is reduced over long
distances. This application is typically used for
short distance, data and audio/video applications
