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 a fiber optic cable?
Cladding in optical fibre is done for the total internal reflection of the waves propagating inside the fibre. The core of the fibre is made of material with less refractive index value than the material covering the core. When wave falls on the high refractive index material passing through the core it is reflected back.
What is the critical angle of a cladding?
The critical angle for the boundary between two materials (such as the core and cladding of an optical fibre) is: θc = arcsign(n2/n1) Where n2 is the refractive index of the cladding layer. and n1 is the refractive index of the core layer. If we use a simply unclad fibre where the core has n1=1.50 and the air surrounding it forms a layer of n2=1.00 θc = 41.8 degrees.
Which types of fiber optic cable would have a core size of 8nm and a cladding size of 125nm?
Single-mode Fiber
How does fiber optics transmit data?
Fibre Optics transmit data via refraction. It uses the concepts of Core and cladding.
Purpose of cladding in optical fiber its density relative to the core?
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 exactly is a fiber optic cable?
fiber optic is a cable of nylon fiber. it is made up of two layers. one is outer coating and inner one is cladding. refractive index of cladding is less than that of outer core. light is reflected inside it and hence convey messages
How is the core and cladding size of a fiber optic cable measured?
Cheryl doesn't know however she says to check the internet. It's probably in Metric though.
Why refractive index of core is lower than cladding in optlical fiber?
because in the fiber optics the transmission of the light waves are through core and cladding is to cover the core
Why core refractive index should be greater than cladding?
yah! i think.....
Core of fiber optic cable?
Fiber Optic Patch Cord is used to interconnect Transmission equipment to the Fiber optic patch panel. we got 2 kind of fiber optic patch core according to the mode: single mode patch core (SM） and multi-mode patch core(MM). and several kind according to the connector: sc, fc, st, lc patch core etc.
What type of cable should be used for a very fast network?
Optacal fiber cables are the fastest network cables in which the signals are transmiited nearly at the speed of light. they are very expesive because they are made of fiber glasses.
Will water pass through the core of a fiber optic cable?
no the core of a fiber optic cable is made of solid glass, making it impossible to pass anything but light through it.
