Quickly diagnose network wiring issues before they disrupt installations or maintenance work. This network cable tester checks Ethernet and phone line connections including RJ45 LAN cables, Cat5, Cat5e, Cat6, Cat6A, and RJ11/RJ12 telephone lines. The tester detects common cabling faults such as open circuits, short circuits, crossed pairs, and miswires, helping technicians verify proper termination and cable continuity. A main unit and remote module allow cable mapping and testing across long runs, with a maximum test distance up to 1000 m. Integrated PoE detection up to 60V helps identify PoE switch power status and type, while clear LED indicators display test results for fast, straightforward troubleshooting during network installation and repair.
Multi‑Cable Compatibility for Network and Phone Lines: Tests a wide range of connectors and cable types including RJ45 Ethernet, Cat5, Cat5e, Cat6, Cat6A, and RJ11/RJ12 telephone lines such as
