In IT, optical fibers are responsible for signal transmission by transmitting light signals over long distances at the speed of light and with enormous data capacity. They can transmit large amounts of data simultaneously and without delay.
A fiber optic cable consists of quartz glass or quartz sand and is made up of various long, thin glass fibers. It is formed by a bundle of glass fibers. A single fiber has a diameter of 250 micrometers and is as thin as a human hair. They consist of a core, a cladding and an outer sheath. The cladding is responsible for guiding the light wave signals and the outer cladding gives the glass fiber its robust but flexible properties.
There are different types of fiber optic cables, e.g: Universal cables, patch cables, pigtails or outer and inner cables. In many areas of IT infrastructure, fiber optic communication has replaced copper cables due to its greater performance and efficiency.
