Before entering fully into the meaning of the term fiber optic, we will proceed to know the etymological origin of the two words that shape it:
-Fiber, in the first place, derives from Latin, exactly from “fiber”, which means “fiber”.
-Optics, secondly, comes from the Greek. Specifically, it emanates from “optikos”, which is the result of the sum of two lexical components of that language: the noun “ops”, which can be translated as “sight”, and the suffix “-tikos”, which is used to indicate "relative to".

The fibers are threads that make up a fabric or that can be used in various ways at the industrial level. Optics or optical , on the other hand, are terms that may refer to the study of phenomena linked to the light (the electromagnetic wave that the human eye can perceive).

With these definitions, we can focus on the concept of optical fiber . This is the name of transparent filament , usually glass, which is used for data transmission through light pulses .

The optical fiber, therefore, is a information transmission medium which is used to develop telecommunications networks. The light signals that, enclosed in the fiber, circulate through these networks , allow to represent the information.

The transmission speed offered by the optical fiber is very high. That is why it is a medium chosen for sending data over long distances, since it also has several advantages over other systems.

He bandwidth The low weight and flexibility are some of the strengths of the optical fiber, which does not produce or suffer electromagnetic interference.

In the same way, we cannot ignore another important series of fiber optic advantages, such as the following:
-It occupies very little space.
-It is really very safe.
-It is identified by offering a great resistance to both heat and corrosion and even what is cold.
-When you suffer a breakdown, it is very easy to detect where the problem lies in it thanks to what is known as reflectometry.

As negative aspects, the fragility of the filaments and the cost of the transmitters and the receivers of the signals appear.

With regard to its disadvantages, we cannot forget some of these:
-On occasions, the joints that need to be made are complex and require time.
- Under no concept, it can transmit what is electrical energy.
- The one that is defined as of conventional type cannot carry out the transmission of what are great powers.

In practice, they are used optical fibre wires that bring together several of these transparent filaments and protect them. The signals , therefore, they are transmitted through these cables that, equipped with connectors, can be connected to switches Ethernet and to other devices.

There are different types of fiber optics taking into account criteria such as their design or the mode of propagation. So you can talk about the multimode, the single mode, the tight structure, the loose structure ...
