The Hioki 3665-20 is a handheld LAN cable tester to easily test wire map, measure cable length and identify twisted-pair cables, and is useful for verifying connections after installing connectors on cables. Optional terminators that facilitate easy identification of multiple cables make the LAN cable tester especially convenient for testing cables in working networks in the event of faults caused by open- or short-circuited cable wiring.
