2.6.4 Cable Testers If the cable is not accessible, cable testing tools can also be used to diagnose intermittent connectivity or poor performance issues. A cable tester reports detailed information on the physical and electrical properties of the cable. For example, it can test and report on cable conditions, crosstalk, attenuation, noise, resistance, and other characteristics of a cable run. Devices classed as certifiers can be used to test and certify cable installations to a performance category—for example, that a network is TIA/EIA 568 Category 6A compliant. They use defined transport performance specifications to ensure an installation exceeds the required performance characteristics for parameters such as attenuation and crosstalk.

It is best to verify wiring installation and termination just after you have made all the connections. This means you should still have access to the cable runs. Identifying and correcting errors at this point will be much simpler than when you are trying to set up end user devices. Copyright © The Computing Technology Industry Association, Inc.
