6 Overall dimension: 60×160×120

【Detecting Principles and Methodology】

    By sending a specified electrical signal to underground optical cables, the optical cable failure locator determines the running direction and the depth of buried optical cables based on the principle that the received signal is the smallest (almost zero) when the probe is vertically tangent to the magnetic horizon.
