Testing Optical Fiber

New Standard On June 20, 2002, the Category 6 (or Cat 6) addition to the TIA-568 standard was published. This new standard specifies the original set of performance parameters that need to be tested for Ethernet cabling as well as the passing scores for each of these tests. A quality cable tester is the Fluke DSP-LIA013 Channel/Traffic Adapter for Cat5e.
