Understanding Patch Cord Measurement Results

Occasionally, customers have noticed failing or asterisk marked patch cord field test results when measuring Category 6A patch cords using a cable certifier. In many cases, these patch cords may pass when measured with another certifier or in a laboratory environment. This may result in one unit providing a ‘pass’ result while another unit reports an asterisk result. In both cases, channels that contain these cords will pass a channel compliance test. This document will explain why these varying results occur and provide steps to take if presented with the condition during field testing.
