FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -It is used glass threads (fibers) to transmit data, each of which is capable of transmitting in the form of light waves. Answer: fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves.

Detailed explanation-2: -Fiber optic cable is made of many thin strands of coated glass fibers. Each measures about eight microns-that’s smaller than a strand of human hair. Digitized information is “coded, ” or placed on to light pulses for transmission. It travels along the glass fiber at the speed of light-186, 000 miles per second.

Detailed explanation-3: -Fiber optics, or optical fiber, refers to the technology that transmits information as light pulses along a glass or plastic fiber. A fiber optic cable can contain a varying number of these glass fibers–from a few up to a couple hundred. Another glass layer, called cladding, surrounds the glass fiber core.

Detailed explanation-4: -Silica glass is the most commonly used in manufacturing because it exhibits fairly good optical transmission over a wide range of wavelengths. Silica can be drawn into fibers at reasonably high temperatures and has a fairly broad glass transformation range.

Detailed explanation-5: -Fiber-optic cables transmit data via pulses of light. Optical fibers are very thin strands of glass or plastic less than 1/10 the thickness of a human hair.
