2. Construction of Fiber Optic
First of all, Fiber Optic cable is very small and thin.
Fiber optic are made by four important parts.
1. Core
2. Cladding
3. Buffer coating
4. Jacket
Core and Cladding are made by quartz glass or
plastic to take good reflection.
3. Type of Fiber Optic
Fiber Optic have two types, multi mode optical fiber
and single mode optical fiber.
Multi mode
Lights are breaking up to lots of modes and are transmitted.
Single mode
Lights are concentrated one mode.
4. How to carry lights.
Fiber optic cable make use of total reflection.
Data about information are converted laser light.
A refractive index of core is higher than that of
cladding to propagate on core.
5. Support performance
Fiber Optic cable use these systems.
1.Transmitter
2. Optical fiber
3. Optical regenerator
4. Optic receiver
For using these systems, we can transport data over
long distance and take the data into our PC.
6. Good point of Fiber Optic
We can choose materials so get lots of advantage.
Good points of plastic are
1. low price
2. strong in regard to arch
3. easy to connect other fiber optics or machines
4. having little weight
For these reason, Fiber optic cable made by plastic
was used transporting a short distance.
7. How to make Fiber Optic
Because Fiber optic cable must have high refractive
index, add Germanium or phosphor in core to
increase refractive index, add boron or fluorine to
decrease it.
First, glass is mixed with some gasses and heat it.
Second, this material pour fiber drawing tower then
it become too thin in order to itself weight.
