optical fibres types and uses

3. What is an Optical Fiber
An optical fiber is a flexible,
transparent fiber made of high
quality extruded glass.

4. History
 John Tyndall wrote
about the property
of total internal
reflection in 1870.
 “When light passes from
one media to another it
bends”

5. It consists of thousands of strands of
fine quality glass or quartz
refractive index about 1.7
thickness about 10-6
coating with lower refractive index (1.5)
material

6. When light is incident at one end the ray of
light undergoes total internal reflection.

7. Each fibre acts as a pipe and such a bundle
of fibers can be used to convey images along
paths of any shape it is pointed.

8. Types of fibers
Multi mode fibers
Single mode fibers

9. Applications of optical fibers
Communication
Medical sciences
Decorative items

10. Conclusion
Fiber optics can be used in both
good and bad ways
Using technology in a proper way
gives us best results.
