Optical attenuator |
Reduces the intensity of light waves, usually so that the
power is within the capacity of the detector. There are
three basic forms of attenuators: fixed optical attenuators,
stepwise variable optical attenuators, and continuous
variable optical attenuators. Attenuation is normally
achieved either by a doped fiber or an offset or core misalignment.
