DY800 Series cable tester according to census bomb optical effects, using optical interferometry method fiber troubleshooting instrument how, by coherent demodulation of light percussion vibration signal into the cable for visual and audio signals, accurately locate and identify the laying on Pipeline (manhole), tunnels and other targets poles overhead cable environment. When using the cable survey instrument, engineers only need to gently tap the fiber optic cable troubleshooting instrument specifications, you can easily recognize the need to find the target cable. DY800 Series Series instrument cable completely replace the previous census cutting, bending, freezing and other methods to identify the fiber optic cable troubleshooting instrument model, is a new detection technique does not damage the cable, its powerful applications can greatly reduce the cable repair and maintenance time, reduce the cost of construction and management, greatly improving efficiency.
