what is non-mater fiber optic cable ?

A non-metal fiber optic cable is a type of optical fiber cable that does not contain metal conductors. Unlike traditional cables with metal conductors, non-metal fiber optic cables use one or more optical fibers made of glass or plastic to transmit data. These cables are often used for high-bandwidth and electromagnetic interference-resistant communication connections, such as in internet, telephone, and television signal transmission. The advantages of non-metal fiber optic cables include their lightweight nature, resistance to electromagnetic interference, higher data transfer rates, and lower signal attenuation.
