MEMS SM Variable Optical Attenuator Cylindrical

There are 2 variants available with different default states: The bright type or the dark type. The bright type has its lowest loss state at 0 V, while the dark type reaches its lowest insertion loss at a voltage between 30-40 V.
The VOA offers highly reliable, durable, long-life operation in a compact package.
