3. What is cable?
In Electrical And Electronic Systems,
A Conductor Or Group Of Conductors For
Transmitting Electric Power Or
Telecommunication Signals From One
Place To Another.
5. Types of Cables
Cables are classified into 5 types depending upon
their purpose as follows:
1. FIBER OPTIC CABLE
2.Twisted Pair Cables
A. Shielded Cables
B. Unshielded Cables
3.Coaxial Cables
6. 1. FIBER OPTIC CABLE :-
A fiber optic cable is a network cable that contains strands of
glass fibers inside an insulated casing. They're designed for
long-distance, high-performance data networking, and
telecommunications. Compared to wired cables, fiber optic
cables provide higher bandwidth and transmit data over longer
distances. Fiber optic cables support much of the world's
internet, cable television, and telephone systems.
7. FIBER OPTIC CABLE
1.Bandwidth is above copper
cables
2.Fiber cable is sized as 4.5 times
which is best than copper wires
3.Installation is extremely easy
thanks to less weight.
4.Less power loss and allows data
transmission for extended
distances
1.These cable are very difficult to
merge so there’ll be loss of beam
within cable
2.These cables are more delicate than
copper wires.
3.Installation of those cables is cost-
effective.
4.Fiber optic cable is dear to put in. It
needs costly machines and trained
specialists to place in fiber optic
cables.

Advantages
8. 2.Twisted Pair Cables:-
Twisted pair cabling is a type of wiring used for
communications in which two conductors of a single circuit are
twisted together for the purposes of improving electromagnetic
compatibility..
9. A. Shielded twisted pair (stp) cables:-
A shielded twisted pair cable or screened cable is an electrical
cable that has a common conductive layer around
its conductors for electromagnetic shielding.
10. •1. It has a higher cost per
foot of wire.
•2. More expensive than
UTP.
•3. ifficult to and maintain.
1.Shielding reduces the chance
of crosstalk and provides
protection from interference.
2.It offers better electrical
characteristics than unshielded
cables.
3.It can be easily terminated
with a modular connector.
Disadvantages
Advantages
A. Shielded twisted pair (stp) cables:-
11. B. Unshielded twisted pair (UTP) Cables:-
Unshielded twisted pair (UTP) is a ubiquitous type
of copper cabling used in telephone wiring and
local area networks (LANs).
12. 1. It is easy to handle.
2. These cables are used in
most of the networking
architecture.
•3. It is less expensive and
less costly compare to other
networking media types.
•1. It can be used up to a
cable segment length of
about 100 meters only.
•2. Bandwidth is limited.
•3. Unable to provide secure
transmission of data.
Disadvantages
Advantages
B. Unshielded twisted pair (UTP) Cables:-
13. 4.Coaxial Cables:-
Coaxial cable is a type of copper cable specially built with a
metal shield and other components engineered to block signal
interference. It is primarily used by cable TV companies to
connect their satellite antenna facilities to customer homes
and businesses.
14. 1. The cost of coaxial cable is
less.
2. It supports high bandwidth
signal transmission compare to
twisted pair.
3. It is easy to wire and easy to
expand due to flexibility.
1. It is bulky.
2. It is expensive to install
for longer distances due
to its thickness.
3. It must be grounded to
prevent interference.
