Advanced Fiber Optic Attenuator with 0-60dB Range & Precision – GAOTek
Refine your optical testing with telecom line tester, achieving precise 0 dB to 60 dB attenuation with accuracy up to 0.1 dB and user calibration.
Description
Overview
GAOTek telecom line tester is variable optical attenuator can conveniently and rapidly complete the continuous variable attenuation of 0 dB to 30 dB or 0 dB to 60 dB of optical signal, with high attenuation accuracy of 0.1 dB, providing the light attenuation function of five commonly used wavelengths, backlight adjustment function, accurate attenuation accuracy and user self-calibration function. This series 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.
