View source for Attenuation signal reduction to dB


== Introduction ==

Many fiber optic technicians are unfamiliar with logarithmic scales and units such as decibel (dB).

This table allows you to get a grasp on the relationship between optical power loss on a logartimic scale (dB) and optical power loss on a liniar scale (%).

Power Loss as also called Attenuation.
