Programmable MEMS Adjustable Optical Attenuator 0~60dB

The desktop adjustable optical attenuator is an optical testing device that integrates optical power regulation and real-time display functions, mainly used for precise control of optical signal strength in optical communication systems.

Continuous adjustable attenuation: Supports attenuation adjustment within a range of 0-60dB or even wider, meeting the requirements of different test scenarios.
Real-time display: Equipped with a liquid crystal screen or digital display module, it intuitively shows the current attenuation value, optical power and other parameters.
Attenuation accuracy: Attenuation accuracy ≤ ± 0.1 dB typ. (0 to 40 dB), ensuring the precision of signal regulation.

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).
Optical fiber sensing network
In the distributed optical fiber sensing system, the signal attenuation at different distances is simulated by adjusting the attenuator to verify the positioning accuracy and signal-to-noise ratio 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.
Wavelength division multiplexer (WDM) production: Calibrate the attenuation of each channel to ensure that the multiplexing/demultiplexing performance meets the standards.
Scientific research and education
University laboratories are used for experiments in optical communication courses, such as research on the transmission characteristics of optical fibers and optical network simulation.
