The switching circuit is composed of triode and diode, etc. The filtering circuit is composed of filtering resistor, filtering capacitor, etc. The probe on the probe rod is downward. When the probe detects that there is an optical cable within a certain distance underground, it can immediately sound and light alarm to remind the excavator operator that there is an optical cable underground and construction should be carried out with caution. However, the optical cable detector has the disadvantages of poor shock absorption ability, weak protection ability of the probe rod when in use, and easy damage of wires during work.
