Eight-Channel Multi-Mode Optical Attenuator With Display 0~35dB
Eight-channel multi-mode optical attenuator with display is an optical attenuator with eight independent channels, each channel can independently control the attenuation amount of optical signal. At the same time, the device is also equipped with a display screen, which can display the attenuation amount of the current channel and other relevant information in real time, which is convenient for users to monitor and adjust. In addition, it also supports the use of multi-mode fiber, which is suitable for different types of fiber optic communication systems.
The working principle of optical attenuator is mainly based on light absorption, light scattering, light reflection, dislocation technology, displacement attenuation and solid state technology. By adjusting the parameters in these mechanisms, the amount of attenuation of the optical signal can be controlled. In the eight-channel multi-mode optical attenuator with display screen, each channel is equipped with corresponding attenuation mechanism and control circuit to achieve independent control.

Eight-channel multimode optical attenuators with display screens are widely used in optical fiber communication and optical testing. For example, in fiber optic communication systems, it can be used to adjust the strength of the optical signal to the dynamic range of the receiver, thereby improving the quality of communication. In the testing and calibration of optical fiber systems, it can also be used to simulate optical signals of different strengths to verify the performance of the system under different signal strengths.
