What is an Optical Attenuator ?

In electrical systems, an Attenuator is usually installed in the passive network for reducing the amplitude of a signal without appreciably distorting the waveform. Similar to electrical system, an Optical Attenuator is installed in optical systems for reducing the amplitude of a signal without appreciably distorting the waveform.

Attenuation : The decrease in signal strength along a fiber optic waveguide caused by absorption and scattering.Attenuation is usually expressed in dB/km.
