Explanation: Cable tester A cable tester contains a Time Domain Reflectometer (TDR) and perhaps additional test circuits. A TDR sends sonar-like pulses through the cable. The TDR detects the reflections, analyzes them and displays the result. A cable tester typically can tell you:

The length of a cable
Whether the cable is correctly wired internally (pin-to-pin wire mapping)
Whether the cable contains a short circuit (wires touching each other through damaged or missing insulation)
Whether the cable contains a broken wire (called an "open")
Whether the cable suffers from electrical cross talk (interference). TDR is used to locate cable faults http://www.hma.tierranet.com/mcse/nettools.html Network Diagnostic Tools Network Tool Function Digital Volt Meters Measures voltage passing through a resistance. Primarily used for network cable (DVM) troubleshooting. Network Monitor Examines packet types, errors and traffic to and from each computer on a network. Oscilloscope Measures amount of signal voltage per unit of time. Displays crimps, shorts, opens, etc. Protocol Analyzer Look inside the packet to determine cause of problem. Contains built in Time-Domain

Reflector. Gives insights to many problems including connection errors, bottlenecks,

traffic problems, protocol problems, etc. Time-Domain Sends sonar-like pulses to look for breaks, shorts or crimps in cables. Can locate a break Reflectors (TDRs) within a few feet of actual fault.
