3. ONGC is multinational oil and gas company.
It is a Public sector undertaking (PSU) of Government of India.
It is largest oil and gas exploration and production company.
It is ranked 11th among top the 250 Global Energy Companies by plants.
GEOdata Processing Interpretation Center(GEOPIC) was established in 1987
at ONGC Dehradun.

4. Transmitting information by sending light though optical fiber.
It based on Total internal reflection.
 It transmit voice, video, and telemetry through local area networks,
computer networks, or across long distances
Telecommunications companies to transmit telephone signals, Internet
communication, and cable television signals

5. The Main component of Optical fiber communication system:-
1.Transmitter
2.Light source
3.Fiber Optic Cable
4.Detector
5.Reciver Circuit

6. Optical fiber is flexible , transparent fiber made by drawing glass or
plastic to diameter slightly thicker than that of a human hair
It is used for illumination and imaging.
Optical fiber is core surrounded by a transparent cladding material
Fiber act as waveguide
Fiber has many propagation path called multimode fiber

7.  1.Bandwidth high bandwidth 10Gigabit/sec low bandwidth gigabits/sec
 2.Distance 40km at 10000 Mbps 100m at 1000 Mbps
 3.Noise immune interface crosstalk
 4.Security almost impossible to tap susceptible to tapping
7

8.  It is based on the principle Total internal Reflection.

9.  Based on modes the fiber cable :-
 1.Single mode fiber cable
 2.Multimode fiber cable

10. 1.Step Index Multimode Fiber
2.Graded Index Multimode Fiber
1.step index Multimode fiber:
It has a larger core , up to 100 micron in diameter .
 It is used for short distance transmission.
2. Graded Index Multimode Fiber
It contain a cote in which the refractive index diminishes gradually from
the center axis out toward the cladding
Light in the core curves helically because of the graded index.

11. Small size and weight
High bandwidth
High security
 High reliability flexibility
High distance

12. 1.fiber cable are used on the ground
2.light emitting (LED) source are limited
3.not to twist or bend fiber optic cables
4.The distance between transmitter and receiver should keep short or
repeaters are needed to boost the signal

13. 1.Transmittter(optical source)
2. Receiver(optical detector)
Optical Source Optical detector

14. Medical :- light guides
Defense/Government:- SONAR , Wiring of aircraft
Data storage :- used as data transmission
Telecommunication:- Transmitting and receiving
Networking help increase the speed and accuracy of data transmission
Industrial :- measurement and as wiring in automobile and in industrial
settings.

15. Fiber optics , a branch of dealing with the transmission of light
through hair thin transparent fibers .
A principal called total internal reflection allows optical fiber
to retain the light they carry .
This is the greatest discovery that man have done in the dies
of communication.
