Gould’s Miniaturized Type Manual Variable Optical Attenuators (MVOA) are available in Single Mode (SM) and Polarization Maintaining (PM) fibers for the wavelengths regimes of 780, 850, 980, 1064, 1310, 1480, 1550, 1560, 1950 & 2000 nm and operates by manually moving a blocking element into the optical path. Gould’s variable optical attenuator is used for the power adjustment in optical modules, systems and test platforms. The MVOA operates by precisely adjusting the power to any desired level through a controlled movement of the blocking element.

Available in 250 μm bare fiber or 900μm jacket with connector options such as ST, FC, SC, LC & FC/APC.
