In-line Variable Optical Attenuator module

Optical attenuator is a passive device used to reduce the power level of an optical signal. It is generally used in single-mode long-haul applications to prevent optical overload at the receiver. Optical attenuator is widely used in CWDM&DWDM, CATV systems, data center networks, test equipment and other high power applications.

In-line Variable Optical Attenuator module is an useful tool for the optical components and systems test.
