What is an optical cable?

Optics, also called optical fibers, is a technology that allows light to travel on thin glass or plastic wires. These wires are usually connected to cables of optical fibers . This type of cable is most often used in the communication industry, because digital information can be converted to light pulses that move along the entire length of the wires. The cables differ in length, from several feet to sufficiently long to cross continents or oceans. It is usually cheaper than the connection of copper. These cables can run to households and businesses, but are usually used for distance communication. However, it was not known that the corners would change easily without losing the signal force and therefore used more often for equal, distance level. First of all, the fiber optics usually offer a better bandwidth, which means they can have more information at the same time. Second, there is less attenuation or signal degradation, in the fiber optical cable. Thirdly, while copper wires use ELECtric signals, fibers use light waves, so there is less chance of interference with signal. Finally, optical fiber wires are made of glass, so there is only a low risk of fire.

The fiber optical cable consists of many optical wires that are connected together. The main part of each wire is an optical glass or plastic core. This core is the fiber of a bright material that must be as clean as possible in order to make light over long distances. Dirt in the nucleus may cause signal degradation.

Any fiber-optic cable uses a process called overall internal reflection to transfer information down on tied wires. This particular reflection occurs when light hits a clean surface at a precise angle and bounces back instead of penetrating it. An example of a complete internal reflection that occurs in nature can be seen when the swimmer is hardly underwater and he n nEbo she sees an ocean bottom that is reflected in the underline of the water. This reflection occurs due to the angle of the swimmer in relation to the surface of the water.

Light pulse in the optical cable of the fiber hits the outer wall of the wire at a similar angle that maintains a light wool forward. The outer surface of the glass wire provides the right angle of reflection so that the light jumps back and there along the length of the cable. The core is closed in Cladding , which is an optically reflective material that helps in this process.

Light signals usually enter the optical cable at one end and are accepted on the other. Signals are usually converted from digital or voice information by computer.
