It combines nine useful functions: cable continuity testing, cable scanning, port status checking, cable length measurement, POE power testing, fiber optic power metering, NVC non-contact voltage testing, and more. This tool can detect various types of faults in RJ45, RJ11, network cables, and fiber optic cables. It provides a comprehensive solution for network construction and maintenance. Cable scanning automatically detects RJ11, RJ45, CAT5, and CAT6 cable connections, ensuring stable connections and preventing network disruptions. Whether used in home or office networks, this tool makes it easy to identify any cable connection issues, thereby ensuring stable network connectivity.For fiber optic connections, it can detect breaks, bends, and other problems. Problems related to optical fibers are quite common. Optical fibers are widely used in the construction and maintenance of fiber optic networks.POE device testing: Checks whether POE devices are functioning properly.Non-contact voltage testing: Useful for safety inspections, industrial maintenance, and home electrical checks. It helps ensure safe and efficient operations for users.Its also useful for enterprise network maintenance, home offices, smart home equipment, IT management, and network equipment debugging. It helps technicians quickly diagnose port-related issues and maintain network stability.Optical fiber repair, installation, and commissioning are also essential tasks, especially in data centers, telecommunications companies, and smart buildings.The device offers nine integrated functions for maintaining and testing all types of cables. For fiber and network equipment, it enables precise cable scanning and fault location, helping to avoid omissions and errors during troubleshooting.
