The Triplett RWV10G Real World LAN and Cable Verifier is break-through technology that brings cable and network verification and testing to a whole new level of reality. Unlike traditional testers, the RWV10G uses digital circuitry and digital testing techniques to perform its tasks. It works with UTP and all Ethernet devices. These tests include traditional TIA568 cable verification (length, opens, shorts, split pairs, wire map) for UTP (unshielded twisted pair). Plus RWV10G's own sophisticated crosstalk, timing and cable parameter tests that yield a UTP cable's category (CAT3, CAT5, CAT5E, CAT6, CAT7) and speed capability (10M, 100M, 1G, 10G).
