MVOA-X Variable Optical Attenuators

Pigtail Style, Miniaturized; Fiber Type SM, MM, PM; 780-2000 nm; Connector Type ST, FC, SC, LC, FC/APC, None; Attenuation Range ≥30 dB

Gooch & Housego’s MVOA-X series of variable optical attenuators (VOAs) offer high precision and stability over a wide attenuation range, with low excess loss in a compact size.

Operated by manually moving a blocking element into the optical path, MVOA-X miniaturized type manual variable optical attenuators are available with single mode (SM), multi mode (MM) and polarization maintaining (PM) fibers in the wavelengths 780, 850, 980, 1064, 1310, 1480, 1550, 1560, 1950 and 2000 nm.

Gooch & Housego (G&H) VOAs are used for the power adjustment in optical modules, systems and test platforms. The MVOA-X series operate by precisely adjusting the power to any desired level through a controlled movement of the blocking element. These VOAs are available in 250 μm bare fiber or 900 μm jacket with connector options such as ST, FC, SC, LC and FC/APC.
