Definitions for "Attenuation Coefficient"
The rate of optical power loss with respect to distance along the fiber, usually measured in decibels per kilometer (dB/km) at a specific wavelength. The lower the number, the better the fiber's attenuation. Typical multimode wavelengths are 850 and 1300 nanometers (nm); single mode wavelengths are 1310 and 1550 nm.
A measure of the rate at which light disappears with depth in Bay waters; large attenuation coefficients occur in turbid waters, and small attenuation coefficients occur in clear water
Characteristic of the attenuation of an optical fiber per unit length, in dB/km.
The relationship between the intensity (I0) of a radiation incident on one side of an absorber and the transmitted intensity (I) for an absorber thickness (t) as expressed by I0 10 exp (-µt).
