Question

What are optical fiber?​

Answer 1

Answer:

An optical fiber is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair.

An optical fiber is a thin fiber of glass or plastic that can carry light from one end to the other.

Answer 2

OPTICAL fibre :

• 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.

• An optical fiber is a flexible, transparent strand of very pure glass that acts as a light pipe to transmit light between two ends of the fiber. Optical fibers have a core surrounded by a cladding layer made of dielectric material.

• There are three types of fiber optic cable commonly used: single mode, multimode and plastic optical fiber (POF). Transparent glass or plastic fibers which allow light to be guided from one end to the other with minimal loss.

• Optical Fiber Communication (OFC) Conference and Exhibition, is a conference and exhibition for optical communications and networking professionals.

• Optical signal is an electromagnetic signal. It has electric and magnetic fields that are orthogonal to each other. Typically, the frequency of this EM wave is extremely high (in the order of THz). Therefore, it is more convenient to. measure it in terms of wavelength.

• Fiber-optic cables are thin enough to bend, taking the light signals inside in curved paths too. ... Artwork: Total internal reflection keeps light rays bouncing down the inside of a fiber-optic cable. Light travels down a fiber-optic cable by bouncing repeatedly off the walls.

• An optical fiber is a cylindrical dielectric waveguide (nonconducting waveguide) that transmits light along its axis, by the process of total internal reflection. The fiber consists of a core surrounded by a cladding layer, both of which are made of dielectric materials.

• The optical receiver is a critical element of an optical communication system since it often determines the overall system performance. The function of the optical receiver is to detect the incoming optical power and extract from it the signal (either analog or digital) that is being transmitted.
