What is an optical fiber?

Optical fiber is a term for any kind of plastic or glass pipe to carry light. The principles behind this are in fact quite old, but in recent years has become incredibly important technology, as communication infrastructure has begun to use this thread to transfer data at an extremely high rate. In addition to communicating from optical fibers, however, it has a number of applications in medicine, consumer products and physics. In addition, it is immune to electromagnetic interference, which can seriously prevent data transmission along normal metal wires. This also adds added safety measures because the optical fiber can survive an electromagnetic pulse that would destroy the metal cables.In inside, so when light goes, it reflects it without losing any light and passes through the fiber to the other end. This basic idea of ​​leading light refraction returns to the 40th century. At the beginning of the 20th century, some practical applications were developed, especially the use of this fiber in dentistry to light upappreciates the inside of the mouth.

In the 1920s of the 20th century, the same basic technology was used to transmit complete images. Over the next decade, the technology has been used virtually to illuminate the interior of surgery, allowing much more accurate operation. It is still used in surgery, especially to facilitate less invasive internal operations. The first real optical fiber appeared in the 1950s and at the end of the decade there were experiments with the type of fiber very similar to the one used today, with glass fibers coated with transparent sheath.

From the TON 1970s, the optical fiber began to be refined, reducing the noise in the signal. This improvement allowed the possibility that the fibers could be used to transmit real communication over long distances. This made it possible to build a massive communication spine that laid the foundations for the Internet. At the dawn of 80.Eral Electric method that could be stretched extremely long springs, up to 25 km (40 km) at the same time, so the massive spine is still facilitating the construction.

Due to the low level of degradation or attenuation, optical fibers are ideal for long distance communication. While the metal wire requires that the repetition device be installed at short distances to ensure that the signal remains strong, the fiber optics can be stretched over long distances without a repeater, which drastically reduces costs. In addition, Fiber is able to transport much more information than a metal wire, which is more advantageous even at short distances, such as Those within the network situation in one building. Since the fiber does not lead electricity in the same way as a metal wire, it is safe to use in environments with high voltage, where traditional involvement could be dangerous.
