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…

Optical Time Domain Reflectometer (OTDR)

Definition: OTDR is an acronym used for Optical Time Domain Reflectometer. It is an instrument that is used to detect or analyze the scattered or back reflected light through an optical fiber due to impurities and imperfections in the fiber. The operating principle of an OTDR is similar to that of radar. OTDR performs timed…

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…
