What does an Optical Attenuator do ?

With the advancement of DWDM technology, as well as the potential to flexibly upgrade the reconfigurable optical add-drop multiplexer (ROADM), the demand for optical attenuator is sure to soar, especially for optical variable attenuator.

  Optical Attenuators, or fiber optic attenuators, are used in optical communications to reduce optical fiber power at a certain level. Generally, the attenuator…
