The optical cable is a non-metallic cable composed of one or several optical fibers. Each of them is wrapped in a plastic casing in a specific color, which indicates the particular type of fiber. It
is a more advanced technical solution for long distance transmission of
information from standard copper coaxial cables because it can carry
larger volumes of data with significantly lower loss and signal
disturbances, transmission distances are incomparably longer and have low risk of corrosion.
The optical cable is made of fiber optics, which are long, flexible, hair-strings of ultra-clear glass. Optical fibers are formed when pre-prepared blanks - portions of specially made glass - are heated between 3000 and 4000 degrees and then pulled at a rate of 66 feet per second. As the optical fiber is pulled out, it is constantly seen under a laser micrometer that observes its diameter to be the same from start to finish.
