The Multi-channel MEMS Single-mode Optical Attenuator Starts Up Quickly
The programmable MEMS attenuator is based on micro-electromechanical systems (MEMS) technology. It controls the mechanical movement of the micro-mirror/light-blocking plate through electrostatic drive or thermal drive to achieve dynamic adjustment of the attenuation amount of the optical signal. Its core advantages include:
High precision and rapid response
Wide wavelength coverage and low loss
Miniaturization and integration
Low power consumption and high reliability

Typical application scenarios
Testing of optical communication systems
Optical module development: Adjust the optical power at the transmitting end, test the sensitivity and dynamic range of the receiver. For instance, in the testing of 400G/800G optical modules, it is necessary to simulate different attenuation scenarios to verify performance.
DWDM system debugging: Balance the power of each wavelength channel to avoid nonlinear effects (such as four-wave mixing). MEMS VOA supports a dynamic range of 60dB and can cover the attenuation requirements of the C+L band.
Optical Network Management
Optical automatic gain regulation: In optical amplifiers (such as EDFA), the input/output optical power is adjusted in real time to ensure the stable operation of the system.
Production of optical devices
Optical switch test: Adjust the input optical power and test the consistency of the extinction ratio and insertion loss of the optical switch.
Production of wavelength division multiplexers (WDM)
The field of optical sensing
Optical sensor sensitivity adjustment: By precisely controlling the attenuation of the optical signal, the measurement accuracy and stability of the sensor are optimized.
