Use the Fluke 620 advanced cable tester to test cables for length and connectivity. Background Work with several cables that have already been made. Test them for basic continuity breaks in wires shorts two or more wires touching using a basic cable tester. In future labs similar cables will be created. Simple Cable Testers There are a number of basic cable testers available for less than U.S. 100. They usually consist of one or two small boxes with RJ-45 jacks. Plug the cables to be tested the RJ-45 jacks. Many models are designed to test only Ethernet UTP cable. Both ends of the cable are plugged in to the proper jacks. The tester will test all eight wires and indicate whether the cable is good or bad. Simple testers may have only a single light to indicate the cable is good or bad. Other testers may have eight lights to indicate which wire is bad. The testers have internal batteries to do continuity checks on the wires. Advanced Cable Testers Advanced cable testers such as the Fluke 620 LAN CableMeter perform basic cable testing functions and more. The Fluke 620 Advanced cable testers can cost from hundreds to thousands of U.S. dollars. Advanced cable testers will be used in future labs to do wire 1 - 2 CCNA 1 Networking Basics v 3.0 - Lab 3.1.9b Copyright 2003 Cisco Systems Inc. maps as well as other tasks. The 620 LAN CableMeter is a cable tester designed to verify connectivity of all LAN cable types. This rugged tester can measure cable length test for faults and show the distance to the defect. Open faults include opens shorts reversed crossed or split pairs. Each 620 LAN CableMeter comes with one cable identifier. The Fluke 620 is more advanced because it performs more functions Requires only single-person verification Tests all LAN cable types UTP STP FTP Coax Detects a multitude of wiring .
