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.
