optical fibre use the phenomenon of total internal reflection.In optical fibres glass of high refractive index is coated with a thin layer of glass of lower refractive index .the rays of light entering through its one end strickes the interference between the 2 glass surfaces at an angle greater than critical angle .this ray will be totally reflected along the whole length of fibre. light can thus travel the length of fibre and emerges from its another end without loss of intensity.

∙ 14y agoWell, there are lenses that help us see near and far. These are concave and convex. Concave lenses are curved inward on both sides (like a cave) and convex lenses have both sides curving outward. Concave make you see things smaller and convex make you see everything bigger.

∙ 10y agoOptical switches are a technology that operates on fiber optic lines to work similar to traditional electrical switches. There are two kinds of optical switches: slow switches which are operated by mechanical means which physically move an optical fiber. These are used as long-term routing solutions if there is a fault in the line. Fast switches are operated using magnetic technology to do logic operations (computations) on the optical lines.

Describe refraction and reflection with respect to Fiber Optical Cable?
Describe refraction and reflection with respect to Fiber Optical Cable?
Is optical fiber ihollow or not?
The main part of an optical fiber is a glass fiber (NOT hollow) within another glass fiber of another type of glass. Both types of glass have a different index of refraction; the signal travels through the inner glass fiber.
What is numerical aparture in optic fiber?
Numerical aparture is the light collecting capability of the optical fiber.
In optical fiber propagation loss is increases or decreases with increase in length of the fiber cable?
Increases with length and connections.
What is optical networking hardware?
Optical networking hardware entails the various components used in optical technologies. Some of the common hardware include routers, optical fiber, electronic devices and so much more.
What is the optical range of optical fiber?
40 GHz
How does an optical transmitter sends signals to the optical fiber?
Usually, there is a laser diode that is optically coupled to the fiber.
Is cross talk is possible in optical fiber?
One of the advantages of optical fiber is that it is NOT susceptible to cross-talk.
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? "

Is optical fiber spherical?
no, its cylindrical
What is fiber optic sensor?
An optical fiber is a glass or plastic fiber that carries light along its length. Fiber optics is the overlap of applied science and engineering concerned with the design and application of optical fibers.
Is fiber obtics a good conductor of electricity?
No. An optical fiber is a slim hair composed of glass. Glass is a fine insulator, and an optical fiber doesn't conduct electricity at all.
Is optical fiber unidirectional?
The optical fiber can be used both as unidirectional and bidirectional. The main application of optical fiber is in long-distance links, so there exists no need to employ them as unidirectional. For each direction different wavelengths are used to modulat the signals. At the same time many bidirectional signals can travel through the same optical fiber.
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.
