Mechanical VOA
GROWSFIBER's mechanical Variable Optical Attenuator (VOA) is a micro-optic component designed to control the attenuation of the optical signal passing through it. The desired attenuation can be precisely achieved by adjusting a screw. It can be used to precisely balance the signal strengths in fiber circuits, and balance an optical signal when evaluating the dynamic range of the measurement system. Operating wavelength, fiber type, fiber length and connectors can be customized.
