【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.
