The all-in-one T013-001-POE Network Cable Continuity Tester is an essential tool for cable installers, system integrators or anyone else working in telecom or LAN environments. It allows you to test wiring continuity for Cat5e, Cat6, Cat6a and telephone cable assemblies at the flip of a switch. A combination of main tester unit and removable remote tester unit, the T013-001-POE identifies crossed wires, short circuits and open circuits in live RJ11 and RJ45 cables. It also identifies the PoE standard used—IEEE 802.3af (15.4W PoE) or IEEE 802.3at (30W PoE+)—and the power sourcing equipment type (Endspan, Midspan or both). When not in use, the two-piece T013-001-POE stores safely in its handy carrying case.
