Gradient neutral density filter is a "precision potentiometer" in optical communication system, which is widely used. Optical attenuator is the main optical equipment in the field of optical communication. It is a necessary tool for the measurement of optoelectronic devices, optical passive devices, optical fiber, optical fiber, optical fiber communication equipment, as well as the construction and maintenance of optical fiber communication system engineering. It can be divided into fixed attenuator and variable attenuator according to the change of attenuation.
The fixed attenuator is mainly used to adjust the optical loss of optical fiber transmission lines.
The attenuation of the variable attenuator can be changed in a certain range, which is used to measure the sensitivity and dynamic range of the optical receiver.
