Optical Fiber Communication

Graded Index Fiber

Definition: Graded Index fiber is another type of optical fiber in which the refractive index of the core is non-uniform. This non-uniformity is present because the refractive index is higher at the axis of the core and continuously reduces with the radial movement away from the axis. However, the refractive index of the cladding is …

Nd:YAG Laser

Definition: Nd:YAG laser is the short form used for Neodymium-doped Yttrium Aluminium Garnet. It is a solid state and 4 level system as it consists of 4 energy levels. Nd ion is rare earth metal and it is doped with solid state host crystal like yttrium aluminium garnet (YAG – Y3Al5O12) to form Nd:YAG laser. …

Optical Network

Definition: An Optical Network is basically a communication network used for the exchange of information through an optical fiber cable between one end to another. It is one of the quickest networks used for data communication. As we already know that data signal through an optical fiber is transmitted in the form of light pulses. …

Rayleigh Scattering

Definition: Rayleigh scattering is the phenomena of scattering of light particles majorly by the molecules of gas (sometimes also by solid and liquid). This scattering of light was first noticed by Lord Rayleigh in 1871 and thus named so. Basically when electromagnetic light propagates through air, then the back and forth movement of electrons inside the …

Splicing of Optical Fibers

Definition: Splicing of optical fibers is a technique used to join two optical fibers. This technique is used in optical fiber communication, in order to form long optical links for better as well as long-distance optical signal transmission. Splicers are basically couplers that form a connection between two fibers or fiber bundles. At the time …
