Optical fibres are used to transmit light over distances of up to several hundred kilometres. A typical optical fibre consists of a cylindrical glass core, just a few micrometres in diameter, surrounded by a layer of a slightly different type of glass known as the cladding. Light in the core travels slightly slower than light in the cladding and this property tends to keep any light sent into the core from one end of the fibre from leaking out, until it reaches the far end. <a href="http://gow.epsrc.ac.uk/ViewGrant.aspx?GrantRef=EP/C014731/1" target="_blank" rel="nofollow">http://gow.epsrc.ac.uk/ViewGrant.aspx</a> The cladding is a glass sheath that surrounds the core. The cladding acts like a mirror, reflecting light back into the core. The cladding itself is covered with a plastic coating and strength material when appropriate. <a href="http://www.linktionary.com/f/fiber-optic.html" target="_blank" rel="nofollow">http://www.linktionary.com/f/fiber-optic

What are the Elements of optical fiber communication link?
If light meets the inner surface of the cladding (the core - cladding interface) at greater than or equal to Qc then TIR occurs. So all the energy in the ray of light is reflected back into the core and none escapes into the cladding. The ray then crosses to the other side of the core and, because the fiber is more or less straight , the ray will meet the cladding on the other side at an angle which again causes TIR. The ray is then reflected back across the core again and the same thing happens. In this way the light zig zags its way along the fiber. This means that the light will be transmitted to the end of the fiber. In reality the light which enters the fiber is a focused beam, consisting of many millions of "rays" behaving in a similar way. They all zig zag along the core of the fiber, crossing over each other, and filling up the core with light. A pulse of light traveling along the core of the fiber is really a bundle of these rays.

Objective type question on optical fiber?
An objective type of question on optical fiber is on that focuses on the integral part of fiber optic. A good question would be, " Why are optical fibers immune to EMI? "
What is Finisar's motto?
Finisar's motto is 'World's Largest Supplier of Optical Communication Components, Defining the Future of Optical Communications'.
What is difference between optical rotation and specific optical rotation?
Optical rotation is the turning plane of linearly polarized light as it travels through certain materials. Specific rotation is the property of a chemical compound as the change in orientation of a plane of light.
What is cladding in an optical cable?
A layer of a glass surrounding the center fiber of a glass inside a fiber-optic cable is called cladding.
What do you mean by optical density?
optical density is the amount of light
What is the effect of decreasing the incubation time on optical density?
The effect of decreasing incubation time on optical density is that optical density decreases. Incubation time and optical density have a proportional relationship.
What is the function of core and cladding in an optic fibre?
in an optical fiber total internal reflection takes place between core and cladding. when core has greater refractive index than cladding. if n1=n2 then their is no TIR.
What is the Purpose of cladding in fiber optical cable?
prevent light loss it reflects the signal back to the core. network + guide to networks pg106 Edition 4.
What is optical density of diamond?
The optical density of a diamond can be found on the RI (refractive index).It is 2.417
Does a substance having high optical density have to have a high physical density?
It's not necessary. If a compound has high optical density, it means that it absorbs more light at the given wavelength than some reference compound. There is no simple relation between density of matter and optical density. Even more I am pretty sure you can find a lot of compounds with lower densities (of matter) but having high optical density.
What is an optical fiber?
#Optical fiber consist of a central core made of class or plastic which is surrounded by a cladding of material of refractive index slightly less than that of core and a protective jacket of insulating material. There are three types of optical fiber configuration.
