MEMS Variable Optical Attenuator Optic Fiber Variable Attenuator VOA
The Springtek MEMS VOA (Micro Electro-Mechanical Systems Variable Optical Attenuator) is a micro-optic component designed for next generation, dynamically configurable optical networks. It is based on the Photonic Integrated Circuit (PIC) and electrostatic MEMS technology. The reflective mirror MEMS technology enables the creation of products with high attenuation levels and can be configured as bright or dark devices. When combined with the advanced packaging and manufacturing capabilities, this results in a new category of MEMS components that are designed to exceed specifications for performance, compactness, manufacturability and reliability. Springtek provides a series of customized MEMS VOA products to meet different requirements on operating wavelength, attenuation type, drive voltage, fiber type, fiber length, input connector, and output connector.
