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.
