____ is a very fast network media. It contains multiple (sometimes several hundred) clear glass or plastic fibers, each about the thickness of a human hair. Each fiber has the capacity to carry data for several television stations or thousands of voice conversations, but each fiber can only send data in one direction. Data sent over a fiber-optic cable is represented by light pulses and is sent at speeds of up to trillions of bits per second

A fiber optic cable can be defined as a type of wired connector which are either made of glass or plastic and they are typically used for connecting one network device to another, so as to form a computer network and enable the continuous transmission of data between them.

In Computer technology, fiber optic cables (FOCs) are commonly produced through the use of several concentric layers of transparent material such as glass or plastic, with each having a slightly different index of refraction for light waves and about the thickness of a human hair.
