Today, fiber optic cables are widely used to build entire systems that transmit data over long distances. Now, in general, many areas of human life cannot do without such elements as fiber optic cable, buy which is offered by a lot of companies on the modern market.
I must say, such systems are built on the basis of special light fibers . In turn, the fiber made from glass becomes their main element. It is this that is the main guide. But on the outside, this fiber is covered with another layer of glass. Compared to the core, this part has lower refractive indices. The rays of light propagate only along the core, while they do not go beyond its limits. The cover layer of the envelope serves to reflect this light and maintain its current position.
Diode or semiconductor laser - these are the elements that create the flow of light itself. Optical patch cord is a type of equipment that is also built on approximately the same technologies.
In our country, the market for optical products has more or less developed only by 2009. It was by this time that optical fibers and other similar designs managed to gain a good reputation even among professionals. Optical fibers have come to be regarded as the optimal scalable and viable option for broadband cabling that provides access to the global network. Operators are still investing in these devices, even if the economic situation is rather difficult.
It is probably difficult to imagine that optical technologies were developed a long time ago. But this is actually the case. As early as in 1840 , the first experiments with these technologies were carried out. But it was only in the twentieth century that this technology found practical application. At that time, it was first shown how exactly it is possible to transmit entire images over optical fibers.
All optical fibers that were produced at that time were originally multiphase. This means that up to hundreds of light phases were transmitted at once. At the same time, connectors and optical transmitters could be inexpensive due to the increased diameter that the core possessed. Fibers of higher productivity began to be used only after some time. In this case, only one phase could be broadcast.
