1. Introduction of the Fiber-Optic
We hear about Fiber-Optic when we are
talking about telephone, internet etc.
Fiber-Optic is made from glass.
It’s very thin.
It’s used to carry digital information long
distance.
It’s used as image processing on medical,
machine technology.

2. Structure of Fiber-Optic
Fiber-Optic consists of three parts - Core,
Cladding, Buffer coating.
Core is center of Fiber-Optic that is fiber
made from glass which light passes.
Cladding is surrounding core.
Buffer coating protects from outside
damage for core.
There are two types of Fiber-Optic.

3. More information about Fiber-Optic
One type of Fiber-Optic is single mode.
Single mode fiber has small core.
Another type of Fiber-Optic is multi mode.
Multi mode fiber has large core.
Fiber-Optic can be made from plastic.
If many Fiber-Optics are bundled, it’s called
Optical Cable.

4. Mechanism of passing light into fiber
Fiber-Optic (Fiber cable) isn’t used straight
condition.
When Fiber-Optic carries light, Fiber-Optic
uses total reflection of light.
Cladding doesn’t absorb light from core.
So, light can pass long distance into core.
But, light signal may be attenuated by bug
in the glass.

5. How to relay of Fiber-Optic
Relaying of Fiber-Optic consists of four
parts.
First, Transmitter generates light signals
and encode it.
Second, light signals pass into Optical Fiber.
If we need more long distance, we can use
Optical Regenerator.
At last, receiver receives light and decode it.

6. Characteristics of Fiber-Optic
Fiber-Optic is better than copper wire.
Fiber-Optic is cheaper, thinner, fewer drop
in quality. Moreover, Optic cable isn’t heavy
than copper wire cable.
So, Fiber-Optic is very space-saving thing.
Fiber-Optic is made politely. And test of it is
done.
Fiber-Optic is filling very hight quality.
