Attenuation signal reduction to dB

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 linear scale (%).

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

 

Solution

Optical Power Loss (dB) Attenuation (dB)	Optical Power Loss (%)
0 dB	0%
1 dB	21%
2 dB	37%
3 dB	50%
4 dB	60%
5 dB	68%
6 dB	75%
7 dB	80%
10 dB	90%
13 dB	95%
15 dB	96.8%
