What are fiber optics used for, how they are made, uses in lighting and advantages compared to traditional copper cables in the transport of information remotely.
How optical fibers are made
They are very thin glass threads, along which the light flows without passing through the walls, used to illuminate or visualize points that are not easily reachable, as in the case of endoscopy, or to remotely transmit a huge amount of information coded through light rays , as occurs in modern internet connections or cable television.
Optical fibers are made up of a glass core surrounded by an annular glass structure, they are divided into the two types called "single mode" and "multimode".
A single-mode optical fiber is capable of transmitting light at a predetermined angle with respect to the axis, while a multimode fiber optic transmits light at different angles.
The great advantages that derive from the use of optical fibers lie above all in the excellent ability to transfer a much greater number of data than copper cables, moreover the transmission of information is almost totally free from losses and interference.
