Wired transmission media includes twisted pair cables, coaxial cables, and optical fiber cables. It provides physically constrained signal propagation with little interference. Wired networks are highly compatible, reliable, secure, and can transmit data at faster speeds compared to wireless networks. However, wireless networks have become more prevalent in everyday devices due to their convenience over wired networks.
Communication involves a sender encoding a message and sending it through a medium to a receiver. It requires a sender, receiver, message, and medium. Common mediums include twisted pair cable, coaxial cable, fiber optics, radio waves, infrared, microwaves, and satellites. Twisted pair is commonly used for analog and digital transmission over short distances. Coaxial cable and fiber optics can transmit over longer distances due to better shielding and bandwidth. Wireless technologies like radio, infrared, and microwaves are used for line-of-sight transmission without cables. Satellites are used when direct transmission is not possible due to obstacles like the curvature of the Earth.

Transmission Media Introduction
3. The transmission medium can be defined as a pathway that
can transmit information from a sender to a receiver.
Transmission media are also called communication channels.
We can group the communication media in two categories
guided media and unguided media. The guided media include
cables and unguided media include waves through air, water
or vacuum.

TRANSMISSION MEDIA
5. TWISTED PAIR CABLE
▹ The most common form of wiring in data
communication application is the twisted pair cable.
▹ As a voice grade medium (VGM), it is the basis for most
internal office telephone wiring.
▹ It consists of two identical wires wrapped together in a
double helix.
▹ The twisting of wires reduces crosstalk. The twisting of
the wires not only protects the signal from internal
crosstalk, but it also protects it form other external forms
of signal interference.
The bleeding of a signal from
one wire to another and which
can corrupt signal and cause
network errors. This form of
signal interference is called
Crosstalk.
CROSSTALK
It refers to a type of
communication channel or
medium that is suitable for
transmitting voice signals.
Voice grade medium
7. Advantage Disadvantage
It is simple
Because of high attenuation, it is
incapable carrying a signal over long
distances without the use of
repeaters.
Easy to install and maintain
It is physically flexible
It has low weight
Its low bandwidth capabilities make it
unsuitable for broadband applications
It can be easily connected
It is very inexpensive
It supports maximum data rates 1
Mbps
Advantage and Disadvantages of Twisted Pair Cable
8. COAXIAL CABLE
➢ This type of cable consists of a solid wire core surrounded by
one or more foil or wire shields each separated by some kind
of plastic insulator. The inner core carries the signal, and the
shield provides the ground.
➢ The coaxial cable has high electrical properties and is suitable
for high speed communication.
➢ While it is less popular than twisted pair, it is widely used for
television signals. In the form of (CATV) cable, it provides a
cheap means of transporting multi-channel television signals
around metropolitan areas.
➢ It is also used by large corporations in building security
systems.
9. Advantage Disadvantage
The data transmission characteristics
of coaxial cables are considerably
better than those of twisted-pair
cables.
Expensive compared to twisted pair
cables
The coaxial cables can be used as the
basis for a shared cable network.
The coaxial cables are not compatible
with twisted pair cables
The coaxial cables can be used for
broadband transmission Le, several
channels can be transmitted
simultaneously (as with cable TV)
Advantage and Disadvantages of Coaxial Cable
10. OPTICAL FIBERS
➢ Optical fibers consist of thin strands of glass or glass like material that carry
light from a source at one end of the fiber to a detector at the other end.
➢ The light sources used are either light emitting diodes (LEDs) or laser diodes
(LDs).
➢ The data to be transmitted is modulated onto the light beam using frequency
modulation techniques.
➢ The signals can then be picked up at the receiving end and demodulated.
➢ The bandwidth of the medium is potentially very high. For LEDs, this ranges
between 20 and 150 mbps and higher rates are possible using LDs.
11. 11
Sheath
Cladding
Core
Diagram
➢ The fiber cable consists of three pieces:
(i) the core, i.e., the glass or plastic through which the
light travels
(ii) the cladding, which is a covering of the core that
reflects light back to the core
(iii) protective coating, which protects the fiber cable
from hostile environment
12. Advantage Disadvantage
It is immune to electrical and magnetic
interference because the information is
travelling on a modulated light beam
Installation problem. Fiber optic cables are
quite fragile and may need special care
It is highly suitable for harsh industrial
environments
Connecting either two fibers together or a
light source to a fiber is a difficult process
It guarantees secure transmission and has
a very high transmission capacity
Because of noise immunity, optical fibers
are virtually impossible to tap. In order to
incept the signal, the fiber must be cut and
a detector inserted
Advantage and Disadvantages of Optical Fibers
13. Advantage Disadvantage
Fiber optic cables can be used for
broadband transmission where several
channels (ie., bands of frequency) are
handled in parallel and where it is also
possible to mix data transmission channels
with channels for telescope, graphics, TV
and sound
•Light can reach the receiver out of phase
•Connection losses are common problems
•Fiber optic cables are more difficult to
solder
•They are the most expensive of all the
cables.
