INFORMATION
The variable optical attenuator can conveniently and rapidly complete the continuous variable attenuation of 0~30dB/0~60dB of optical signal, with high attenuation accuracy of 0.1dB, providing the light attenuation function of five commonly used wavelengths, back light adjustment function, accurate attenuation accuracy and user self calibration function.
The attenuator are mainly used in the construction, upgrading and daily maintenance of optical fiber communication system and network, and widely used in optical fiber construction and maintenance, optical fiber communication, optical fiber sensing, Optical CATV and other fields.
