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 logarithmic scale (dB) and optical power loss on a linear scale (%).

Power Loss (dB) is also known as Attenuation (dB).
