Network cables are used to connect network devices and computers to share resources. There are different types of network cables including fiber optic cables, coaxial cables, and twisted pair cables. Fiber optic cables transmit data using light signals and are the fastest cables capable of speeds up to 10 Gbps. Coaxial cables have a central conductor surrounded by insulating and shielding layers to transmit data via electrical impulses. Twisted pair cables contain two insulated copper wires twisted together to reduce interference and are available as shielded or unshielded versions.

1. Network cable

2. What are network cables?
network cable is network hardware,
Sometimes it made up of copper
wires or fiber.

3. What are the main purpose of
network cable?
• It is used to connect one
network device to other network
devices or to connect two or
more computers to
share printers and scanners.

4. There are different types of
cable
• FIBER OPTIC CABLE
• COAXIAL CABLE
• TWISTED PAIR CABLE

5. Fiber optic cable
• It can be glass or plastic, and is
meant to conduct light instead of
electricity.

6. Components that make up fiber
optic cable
• Outer jacket
• Strength member
• Coating
• Cladding
• Core

8. How do Fiber optic cable
works?
• Using waveguide(core) fiber optic
cable transmit data through light
signal beam.

9. How fast are fiber optic cable in
terms of data transmission?
• It is the fastest data cable, Up to
10 Gbps (a data transfer rate up
to 10 billion bits per second)

10. 10 GBS?
HOW??
Its because Fiber optic
cable using the
technology of light beam

LIGHT!!

11. Coaxial cable
• It is a type of cable that has an inner
conductor surrounded by an
insulating layer, surrounded by a
conductive shielding.

12. What are the components that
make up the coaxial cable?
• Outer jacket insulation
• Conducting shield
• Dielectric
• Conductor

13. Outer jacket Conducting

14. The example below shows a typical
T-connector with BNC fittings.
Attach to a port
of NIC

15. BNC connector attached to a
thin Ethernet cable.

16. How coaxial cable
use to transmit
data?
Answer:
As is typical
Ethernet
cable, data
pass through
electrical
impulses!!

17. Twisted pair cable
• is a type of cable made by putting
two separate insulated wires
together in a twisted pattern and
running them parallel to each other.
• twisted pair cabling is often used to
help avoid certain kinds of signal
interference.

18. Two different types of twisted
pair cable
• UTP CABLE (Unshielded twisted pair)
• STP CABLE (Shielded Twisted pair)

19. UTP CABLE
• It is a 100 ohm
copper cable that is usually
consists of 8 unshielded twisted
pairs surrounded by an outer
jacket.

21. STP CABLE
• An STP (Shielded Twisted Pair) cable is
very similar to a UTP cable, except that
it has a metal foil sheath around each
pair of wires, or around the entire set of
wires.

wait! But what
are the purpose
of outer jacket in

24. How bout the
wire insulation?
It separate and
protect the
copper wire or
conductor.
