An optical attenuator, or fiber optic attenuator, is a device used to reduce the power level of an optical signal, either in free space or in an optical fiber. The basic types of optical attenuators are fixed, step-wise variable, and continuously variable. The power reduction is done by such means as absorption, reflection, diffusion, scattering, deflection, diffraction, and dispersion, etc.

Optical attenuators are commonly used in fiber-optic communications, either to test power level margins by temporarily adding a calibrated amount of signal loss, or installed permanently to properly match transmitter and receiver levels. The power reduction is done by such means as absorption, reflection, diffusion, scattering, deflection, diffraction, and dispersion, etc.

An optical attenuator, or fiber optic attenuator, is a device used to reduce the level of an optical, either in free space or in an. Bulk attenuators can operate based on several principles, such as filter wheels with neutral density filters, rotated.

Optical attenuators are critical devices used in managing the intensity of optical signals in fiber optic communications. Key requirements include minimal effect on the beam profile, low wavelength and polarization dependence, and sufficient power handling capability. The attenuator circuit will allow a known source of power to be reduced by a predetermined factor, which is usually expressed as decibels.
