Portion of solar radiation directed back into space as a result of particle scattering in the atmosphere
{i} part of solar radiation that is guided back into space due to particle scattering in the atmosphere
A small fraction of light that is reflected out of the original direction of propagation by scattering suffers a reversal of direction In other words, it propagates in the optical waveguide towards the transmitter
The deflection of radiation by scattering processes through angles >90o with respect to the original direction of motion
The return of a portion of scattered light to the input end of a fiber; the scattering of light in the direction opposite to its original propagation
Refers to light diffraction at microscopic non-uniformities in the index of refraction of the optical fiber causing backreflection of optical power towards the source
Refers to light diffraction at microscopic non-uniformities in the index of refraction of the optical fiber causing back reflection of optical power towards the source Used in OTDRs
