Optical attenuator
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.

Wavelength DependencePolarization DependenceReciprocityPrecision of LossReturn LossCustom VersionsFor many applications, it will not be a problem if the obtained insertion loss slightly deviates from the specification (e.g. by 1 dB), or if it slightly changes over time. Example cases, however, one may require a higher precision.See more on rp-photonics optical-solution
