| attenuation |
A general term indicating a decrease in power from one point to another. In optical fibers, it is measured in decibels per kilometer at a specified wavelength.

| attenuation |
The total light lost from a beam of light propagating through water. These losses are due to scattering from suspended materials and the molecular scattering of the water itself, and to particulate and dissolved materials and the water itself absorbing the light. The amount of attenuation is primarily dependent upon the wavelength of the propagated light, the concentration of suspended materials and the concentration and composition of both particulate and dissolved absorbing materials.

| attenuation |
Loss of signal power between points. In optical cables, attenuation is a ratio of input power vs. output power, measured in decibels per unit length, usually dB/km.
