Variable Optical Attenuator (Low WDL)
MEMS VOA is based on micro-electro-mechanical system technology. It allows a precise level of attenuation by rotating the MEMS mirror to change the coupling of light between the input and output fibers. There are 2 variants available with different default states: The bright type or dark type. The bright type has its lowest loss state at 0 V, while the dark type reaches it’s lowest insertion loss at a voltage between 4.5-5V. The VOA offers highly reliable, durable, long-life operation in a compact package.
