High Performance Of 8-Channel Multi-Mode Optical Attenuator With Display

Multimode optical attenuator is a kind of optical device specially designed for multimode optical fiber system, its main function is to adapt to different application requirements by adjusting the intensity of the input optical signal. The following is a detailed explanation of the multi-mode opto-controlled optical attenuator:

Definition and principle
Definition: A multimode optically controlled optical attenuator is a device that adjusts the intensity of the optical signal in a multimode fiber by electronic control.
Principle: It is mainly composed of two parts: multi-mode interferometer and program control unit. The multimode interferometer uses the interference effect to adjust the relative intensity of different wavelengths of light in the transmission path, and the program control unit is responsible for controlling the difference of waveguide length in the multimode interferometer, so as to achieve accurate control of optical signal attenuation.
Second, structure and characteristics
Structure:
Multimode interferometer: The key component of optical signal attenuation, using the interference effect to adjust the intensity of the optical signal.
The program control unit is responsible for controlling the waveguide length difference in the multi-mode interferometer, and changing the waveguide length through electronic devices to achieve accurate control of optical signal attenuation.
Features:
Precise control: The amount of attenuation can be adjusted as needed, and the optical power information is monitored and fed back in real time to maintain a stable attenuation level.
Strong flexibility: suitable for a variety of optical communication and optical system applications, such as optical fiber communication, optical fiber sensing.
