The Gigalight mechanical VOA (Variable Optical Attenuator) 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. Gigalight provides a series of customized mechanical VOA products to meet different requirements on operating wavelength, fiber type, fiber length, input connector, and output connector.
