Parallel Data Measurement With 4/8 Channel Optically Controlled
Optical Attenuator
The U8734 optical attenuator is a 4-channel optical
attenuator with fast and accurate setting function. Its setting
time is only 100ms, which allows multiple attenuators to be set at
the same time, and multiple ports can be measured at the same time,
thus saving a lot of measurement time. In addition, the optical
attenuator has a built-in high precision OPM, ensuring its
stability and accuracy. Its simple and intuitive graphical user
interface and multi-channel data preview make the test status clear
at a glance.
For the specific use of U8734 optical attenuator, it is
necessary to understand its principle and type. The basic working
principle of optical attenuators is to reduce the intensity of
light by absorbing or reflecting part of the light signal.
According to the type, optical attenuators can be divided into
adjustable, fixed and built-in. In practical applications, it is
necessary to determine the optical power that needs to be
attenuated, and select the appropriate optical attenuator according
to the power and attenuation amount that need to be attenuated.
