Optical fiber is a word used to classify a technology of data transmission at high speed.
Many people still confuse the written form and the spoken of the optical fiber. Some would argue that it is the correct fiber optic with no “P” for mute and the other argue that it is a correct way is fiber optic with “P” is silent before “T”.
What actually happens is that the two forms are correct, because, according to the new agreement of the Portuguese language, the “p” is silent, that does not have its pronunciation is made in a word, should be a suppression in the written form.
The optical fiber is very well known by internet users, that to have a connection better and faster, opt to purchase plans that provide for the transmission of data made by optical fiber.
The technology of optical fiber consists of cables that are made of transparent materials and that cause reflection. Another advantage is that they may present a volume that is smaller than a human hair.
What happens with fiber optic cables that are transparent, reflective, light entering it is reflected and begins to travel at the speed greater than the traditional transmissionof power is made by the copper wires that all have always used.
With so much advantage, the main users of this type of technology are the large companies of telecommunications, because in addition to the speed, security in transporting data is much higher than in the traditional system.
After its introduction a few years ago, the technology proved to be essential and irreplaceable, because it is indeed very important for the new digital technologies expand. Thus, the communications in both near and long distances can be constant and without any kind of interruption due to the speed in which they are exchanged the data in this transmission.
These qualities have already been mentioned about the fiber optic will help a lot on the types of communications that use voice and video, because these are the most in need of one of a transmission speed greater.
The core or the interior of the cell core of the optical fibers are made of transparent material, this is deliberate so that they form a type of mirror that will make the light that penetrates the cable is immediately reflected, which in turn will make the transmission of data through that light, fast, and can thus take the data quickly also.
To give you an idea, this core, most of the times it is done by a composition that presents a type of glass that is totally pure, which demonstrates the perfect conditions for the light to be reflected to the maximum.
With the reflection, the data are transmitted in a much faster way, because the light emits the beam in the first end of the cable which, in turn, runs around the cable until you reach the other end at a speed above normal.
Although the core of cables can be done with glass supersensitive and pure, not all have this same composition. Other types of cables of optical fiber have a different composition, such as plastic.
The problem with the fiber optic cables that are made of plastic, is that despite being reflective, they do not present a purity as great as that found in the power used, but connects the transmissions, and optical fibers stronger.
Without this purity of glass, the transmission is a little more impaired, not to mention another negative point, which is the smaller range for this type of fiber optic cable.
Now, to the task of transmitting electrical signals, we have in the fiber optic cable emitted light, which is made from a light source of a laser or light an LED.
This transmitted light by the laser or by the LED undergoes a conversion to become pulses of light. Who does this kind of task are devices developed by the companies of this branch, who have this work well set on computers with special systems.
From there, they driven light which have been emitted by the laser or the LED to make the communication with the devices through fiber-optic cables, featuring binary values that are known as the bit.
These transmitted bits correspond to the data that are being exchanged between one device and another.
Advantages and disadvantages of optical fiber
As we talked about earlier, the advantages to be acquired if you have a fiber optic service to make this transmission of data can be numerous.
Speed, ease, convenience and durability are some of the advantages gained by the fiber optic. The negative points are the values, they are not the materials used in the production of optical fiber that are expensive because they are even more abundant than the traditional, but the way of producing the optical fiber is that it is too expensive.
Singlemode and multimode
When we speak of the cable, multimode, we talk about the most common form that is used in the optical fiber. This form is widely used in the local distance shorter due to the low cost and ease in installation time.
Now, when we talk in cable single-mode, lets it be clear that this is the recommended way for data transmission in optical fibers, especially for large distances, as it travels through the largest locations, and has an increased performance, in addition to suffering less interference.
This happens with both cables singlemode why the materials used in its construction reflect the light more efficiently. The negative point of this way is that the light signal emitted has a limitation, working of a pulse of light at a time and not several at the same time.
