Multi-Mode Optical Attenuator Built-In Power Monitoring Accuracy


The optical attenuation and optical power output can be set quickly and accurately, and the optical power attenuation stabilization time is less than 200 ms.
Multi-channel attenuator is set at the same time, and multiple ports are measured simultaneously, which saves a lot of measurement time;
Built-in power monitoring ensures the stability and accuracy of light attenuation;
Simple operation, intuitive graphical user interface, multi-channel data preview, test status at a glance.
Small size, compact structure.


A multi-mode optical attenuator is a device used to reduce the intensity of the optical signal in a multimode fiber. It is often used to adjust the power of the optical signal to maintain the stability of the system, or to provide repeatable results during testing and measurement. Multimode optical attenuators can be implemented in a number of ways, including using effects such as light absorption, scattering, or interference.
