As fiber optics work?

Glass fiber is used with increasing regularity because of the numerous advantages it offers compared to more traditional data technologies such as copper. But what is fiber optic cables to them effectively?

How are fiber optic cables are made?

Refers to the application of fiber optics to transfer data through light signals to transmit. Most optical fibers are made of glass or, less commonly, plastic. Glass is often usedbecause there is less signal loss over long distances with plastic.

Each optical cable is basically composed of two "layers". The center is called "core" and this is where the signals are sent through the light. Surrounding the core is the second layer, named as the coating. The coating is what keeps the signal within the nucleus, using a principle called total internal reflection. " The coating is reflective, leading indicators of light to travel through the core, while theprevent signal leakage or be absorbed by external components.

Single mode and multimode fiber

Optical components can be grouped into two main categories. The first is called single-mode fibers support a single propagation path, whereby a signal at a time. Single-mode be used for most communication links longer than 200 meters. Alternatively, there are multimode fibers. These usually have a core of large diameter and are used for short-range communication linksor for applications where high power must be transferred.

How is the information passed to the light?

The light signal transmitted through these wires is not actually a continuous beam. Rather, it is composed of short sequences of light signals. This process is derived from the Morse code, the communication system with a series of long and short of the individual values. That's because the computer code consists of only 1 and 0.

Fiber Optics offers many advantages over traditional wires, like copper. optical components, higher transmission speeds, higher speeds and greater reliability. They are safer and actually cost less in the long run compared to the metal. Unlike metal wires, optical wires are immune to electromagnetic interference, have a much lower risk of fire or shorts, and prevent cross talk between the wires next.

For these reasons, the fiber has become the best choice for many industries, including telecommunications systems,> TV broadcasts via cable and data networks.
