Fibre Optical Attenuators are used to reduce the strength of a Fibre Optic signal.
A fiber optic attenuator is a passive device used to reduce the amplitude of a light signal without significantly changing the wave form itself.
Attenuators have a working wavelength range in which they can abosrb the light.
