Cable survey instrument, is a world to use acoustics to identify accurately locate buried in the pipeline (manholes), tunnels and poles for overhead cable and other environmental target device currently. There has been patented in the major regions of the world fiber optic investigation instrument specifications Korea, Japan, US, EU and China. Cable survey instrument is designed for telecommunications engineer or technician tailored precision instruments and equipment used to accurately identify the cable. This device is suitable for people under ambient cable locating wells, tunnels, pipelines, etc., with user-friendly, simple and practical, non-toxic, does not damage the advantages of fiber optic cable. Completely replace the previous survey instrument cable cutting, bending, freezing and other methods, is a new patented technology does not damage a variety of fiber optic cable troubleshooting instrument, its powerful applications, greatly reducing the time and cost of fiber optic transmission network management project, a very greatly improve work efficiency.
