36. What do you mean by Fiber Optic Cable. (5 marks)
Answers
Answer:
A fiber-optic cable contains anywhere from a few to hundreds of optical fibers within a plastic casing. Also known as optic cables or optical fiber cables, they transfer data signals in the form of light and travel hundreds of miles significantly faster than those used in traditional electrical cables.
Explanation:
Fiber-optic cables transmit data via fast-traveling pulses of light. Another layer of glass, called “cladding,” is wrapped around the central fiber and causes light to repeatedly bounce off the walls of the cable rather than leak out at the edges, enabling the single to go farther without attenuation.
Answer:
Fibre optics is a popular technology that has a large capacity to transfer data at a very high speed. A fibre optic cable consists of a central glass core containing a bundle of glass threads, surrounded by several layers of protective materials. The glass threads are capable of transmitting the data converted into light signals at extremely high speed.
