Product Detail Information



TAB (Thermal Arched Beam) VOA is a VOA product family using the MEMS chip with a mirrored vane that actuated by thermal arched beam to achieve precise and stable attenua-tion. The vane attenuates the laser light power by blocking the input laser beam onto the output fiber. The applied volt-age to the device controls the vane displacement, thus the desired attenuation amount.

The TAB VOA is the best-in-class versatile VOA product with uncompromised performance and durability.
