Single-Channel Optically Controlled Optical Attenuator And Optical Power Meter In One
Single-channel optical-controlled optical attenuator and optical power meter two-in-one device is a test instrument that integrates optical attenuator and optical power meter in one. This device has a wide range of applications in optical communication, optical fiber testing, optical research and development, and can provide accurate and fast optical signal testing and control.
Functional characteristics
Light attenuation function:
The device has a single-channel optical attenuation function, which can realize continuous or hierarchical adjustment of optical signal intensity.
Through the built-in precision stepper motor or attenuation element, the user can precisely control the attenuation amount of the optical signal to meet different test needs.
Optical power meter functions:
The device also integrates the function of an optical power meter, which can directly measure the absolute power or relative loss of the optical signal.
The optical power meter has the characteristics of high sensitivity, high precision and wide measuring range, which can accurately reflect the intensity change of optical signal.
Two-in-one design:
The optical attenuator and optical power meter are integrated into one, which greatly saves equipment space and cost.
At the same time, this design also improves the convenience and efficiency of testing, and users can complete the attenuation and measurement of optical signals on the same device.
