Optical fiber is a thin strand of glass that transmits light using the process of total internal reflection. There are two main types: single-mode fiber which uses lasers and multi-mode which uses LEDs. Optical fibers are made by drawing glass into a thin strand and adding protective coatings. They offer advantages like flexibility, light weight, and ability to transmit data over long distances at low cost. Optical fibers are now commonly used for telecommunications, including telephone networks, cable TV, and internet services.

1. About Fiber Optics
Optical fiber is a long strand of very pure glass,
about the size of a thin diameter of a human
hair.
Optical Fiber There are two types of.
One has a small core and infrared laser
transmission is referred to as single-mode fiber.
Has a light transmission of infrared light
emitting diodes and said one large core, and
other multi-mode fiber.

2. Making Of An Optical Fiber
And optical material outer surrounding the
glass center thin fiber light called core is
moved, the core reflects back the light to the
core, called the cladding, the optical fiber is a
plastic that protects the fiber from moisture
damage and called buffer coating There is a
coating.
The optical fiber using a total internal reflection.

3. Optical Fiber Relay System
Encoding transmitter generates an optical
signal, the optical signal is performed in the
short distance optical fiber, optical fiber relay
system when long-distance optical signal
decoding optical regenerator boost the optical
signal received by the optical receiver it is
configured to.

4. The Advantage Of The Optical Fiber
The optical fiber is flexible and is lighter than
conventional low power consumption with high
exercise capacity at low cost.

5. How To Make An Optical Fiber
I made ​the first glass cylinder of reform.
I then draw the fiber from the reform.
I completed the test at the end of the fiber.

6. Example Of The Use Of Optical Fiber
Optical fiber has been used long-distance
telephone, cable television, and the Internet.
