Miniature size
Our miniature sized MEMS variable optical attenuator presents a diameter of only 3.5 mm.
Low power consumption
Our MEMS variable optical attenuators operate with minimal power consumption, leading to energy-efficient operation and reduced heat generation.
Low insertion loss
Our MEMS variable optical attenuators introduce minimal insertion loss, ensuring that the signal strength remains largely intact during transmission.
High Reliability
Our MEMS variable optical attenuators are renowned for their high reliability and long operational lifetime. The MEMS variable attenuator meets Telcordia 1221 reliability standards and RoHS requirements 2015/863/EU.

The MEMS mVOA comes in a hermetically sealed package with a diameter of only 3.5 mm. It is manufactured with the latest techniques in laser welding, achieving optimal stability and improved reliability.

This miniature MEMS variable optical attenuator is ideally suited for gain control in amplifiers and transceivers.

Operating principle of the variable optical attenuator mVOA

The variable optical attenuator mVOA uses an electrostatic MEMS mirror. By applying a voltage (typically 0-5V or 0-6.5V) to a control pin, the electrostatic force moves this tiny mirror. As the mirror changes position, it alters the optical path, thereby increasing or decreasing the attenuation (light blockage). When power is removed, the variable optical attenuator VOA returns to a default state, which can be either "bright" (minimum attenuation) or "dark" (high attenuation), depending on the variant.
