3. What is
Fiber
Optics?
A Fiber Optics is a hair thin
cylindrical fiber of glass or any
transparent dielectric medium.
The fiber which are used for
optical communication are wave
guides made of transparent
dielectrics.
Its function is to guide visible and
infrared light over long
distances.

4. Structure
of Fiber
Optics

5. Core
Central tube of very
thin size made up of
optically transparent
dielectric medium and
carries the light form
transmitter to receiver.
The core diameter
can vary from about
5um to 100 um.

6. Cladding
Outer optical material
surrounding the core
having reflecting
index lower than core.
It helps to keep
the light within the
core throughout the
phenomena of total
internal reflection.

7. Buffer
Coating
Plastic coating
that protects
the fiber made
of silicon
rubber.

8. Outer Jacket
Hundred & thousands of theses optical
fiber are arranged in bundles in optical
cables. These bundles are protected by
the cable’s outer covering, called a
jacket.

9. Modes Of Fiber
Single
Mode
Multi
Mode
The Optical Fiber have
two modes

10. Single
Mode
• Single Mode cable is a single stand of glass fiber with a
diameter of 8.3 to 10 microns that has one mode of
transmission. Single-mode fiber gives you a higher
transmission rate and up to 50 times more distance than
multimode, but it also costs more. Single-mode fiber has a
much smaller core than multimode.

11. Multi
Mode
• Multimodecable is made ofglass fibers,with common
diameters in the 50-to-100micron range. Multimodefibergives
you high bandwidth at high speeds overmedium distances.
However, in long cable runs (greater than 3000feet), multiple
paths oflight can cause signal distortionat the receiving end,
resultingin an unclear and incomplete data transmission.

12. How
Fiber Optics is made?
•Making a Preform
Glass Cylinder
•Drawing the Fiber’s
from the preform
•Testing the Fiber
Three Steps are
Involved in
the manufacturing
of the Fiber Optics

13. Advantages
The life of fiber is longer than copper wire
Handlingand installationcosts of Fiber Optics
is very nominal
It is unaffected with electromagnetic
interference
Attenuationin Fiber Optics is lower than
coaxial cable or twisted pair.
There is no necessity of additional equipment
for protecting againstgrounding and voltage
problems.

14. Disadvantage
Highly skilled staff
would be required
for maintenance
Only point to point
working is possible
on Fiber Optics
Precise and costly
instruments would
be required
Costly if under
utilized.
Jointing of fiber
and splicing is also
time consuming.

15. Applications
• Fiber Optics have wider range of
application in almost all field, some
are been specified below
• In telecommunication field
• In space applications
• Broadband applications
• Computer applications
• In medical applications
• In military applications etc.

16. Conclusion
• This concludes our study of Fiber Optics
communications have looked at how they
work and how they are made. We have
examined the properties of fibers, and how
fibers are joined together. Although this
presentation does not cover all the aspects of
Fiber Optics work it will have equipped you
knowledge and skills essential to the fiber
optic industry.
