Amorphous solid
solid particles are mixed together in a mess. No exact shape such as polymers, glass, rubber, etc. have properties similar to conventional crystalline geometry is different, of course. Therefore, there is a treasure called the refractive index isotropy is the electric field and other properties. Are the same in all directions In addition, amorphous solid is melting less pronounced. When the heat gradually. Weakens the flow The melting temperature of this solid in the long term. Unlike quartz, which has a melting point that is clear and the temperature solid this fusion in the narrow.

The optical fiber
Fiber optic is a glass or high quality plastic Flexible bend 8-10 micron diameter smaller than a human hair measures 40-120 microns, 100 microns paper fiber acts as an intermediary to transmit light from one side to the other side. With nearly the speed of light When used in telecommunications. Making it possible to send - receive data much faster. A distance of more than 100 km in one session.
The highlight of the fiber-optic
The highlight of the fiber-optic has several reasons. Specifically, the point where the advantages of copper conductor cables that will be used as a replacement for copper conductors. These advantages are continuously developed and improved.
The ability to send and receive news and information
When used with a wavelength of 850 nm wavelength light signals over 160 MHz to 1 km in length and up to 100 meters in length, if the reduction would apply to more than one gigahertz frequency was. Therefore better The TPI model Cat 5 cable.
The properties of the optical fiber.
1. Electromagnetic waves can not interfere.
Light is energy, energy is unique and not disturbed by electromagnetic waves. Travel mug in it-free. Interference of light from outside.
2. Light weight.
Optical fiber size 2 axis only weighs about 20 to 50 percent of a Cat 5 cable, the UTP.
3. Small size.
Optical fiber when combined cover material, and then smaller saiyu teepee. About 15 percent of the space, u-wire cat 5 a teepee.
4. Information security is higher
5. There's life and property safety.
All fiber insulation It does not conduct electricity
6. Fracture easily.
7. Optical fiber is expensive
Types of Optical Fiber
1. Single mode
Light guides are used to squeeze the beams directed to the glass pipe. The light distribution sideways minimal.
2. Multi mode.
A fiber optic light distribution that looks out to the side.
The light transmission and light.
The device serves to transmit light or a light source is LED or laser diode. Optical transmission equipment is needed to convert wave power into light waves. The device is light and switch to an electrical signal is a photo diode.
