Q. Which transmission media has the highest transmission speed in a network?
- coaxial cable
- twisted pair cable
- optical fiber
- electrical cable
Answer: Optical Fiber
An optical fiber is a thin fiber of glass or plastic that can carry light from one end to the other. The study of optical fibers is called fiber optics, which is part of applied science and engineering.
Optical fibers are mainly used in telecommunications, but they are also used for lighting, sensors, toys, and special cameras for seeing inside small spaces. It is sometimes used in medicine to see inside people, like down their throat.

Guiding light by internal reflection, the principle that makes fiber optics possible, was first demonstrated by Daniel Colladon and Jacques Babinet in Paris in the early 1840s. John Tyndall included a demonstration of it in his public lectures in London, 12 years later.Researchers at Bell Labs have reached internet speeds of over 100 petabit×kilometer per second using fiber-optic communication.
