What is a fiber optic cable?
A fiber optic cable contains anywhere from one to several hundred optical fibers within a plastic casing. Fiber optic cable (or optical fiber cable) transfers data signals in the form of light and travel anywhere from a few feet to hundreds of miles significantly faster than signals in traditional copper cables.
What are fiber optic cables made of?
Fiber optic cables are made up of glass fibers that transmit light signals over short and long distances. They are used in industrial communications settings as well as telecommunications networks for high-speed data transmission. They are also used to transmit high-power laser energy in such applications as medical lasers for surgery and military laser defense systems. In communications applications, optical fibers are replacing copper wire because they can carry much more information than copper does and at much higher speeds.
Do fiber optic cables get hot?
No. Fiber optics are not heated by the light they carry, and therefore do not emit heat or cause any other type of heating effect.
