Wavelength DependencePolarization DependenceReciprocityPrecision of LossReturn LossCustom VersionsMost fiber-optic attenuators exhibit a relatively high return loss (at least several dozens of decibels), i.e., there is not much light which is reflected back into the input fiber. For some sensitive applications, e.g. when using an attenuator before or after a high-gain fiber amplifier, one may have two use attenuators with particularly high retu...See more on rp-photonics Wikipedia
