Based on proprietary fabrication techniques, MEMSCAP® offers multiple Electrostatically Actuated Variable Optical Attenuators including:

• “high” voltage drive ES-VOA
• low voltage drive ES-VOA
  

The MEMSCAP® Electrostatic VOAs are designed to be driven with less than 15 volts actuation voltage and are reflective type of devices. They exhibit nearly zero power consumption, good stability and reliability.
Our devices can be used in applications like:

• Power equalization in multi-channel, optically amplified networks
• Power Balancing Between Amplification Stages)
• Gain-tilt control in erbium doped fiber amplifiers (EDFAs)
• Dynamic Gain/Channel Equalizers (DGE/DCE) in Dense WDM/ Coarse WDM networks
  • Dynamic Optical Power Control and Channel Equalization
  • Channel Balancing for Optimizing Transmission Performance
• For ROADM power balance
  • Photoreceiver trimming
  • Receiver protection/switch during transmitter turn-ons
