To meet the applicable standards, a Category 6 system must achieve specific performance criteria that certifies compliance of installed LAN Cabling to TIA
Category 6 and ISO Class E standards. Testing must be accomplished using a field tester with accuracy beyond TIA level III requirements traceable to laboratory reference standards. Documentation shall clearly present test result data with professionally designed report layouts that include plots and test data, facilitating at-a-glance analysis of cabling quality and headroom vs. limits.
Attenuation to Crosstalk Ratio (ACR): The ratio of the measured attenuation and the near end crosstalk (NEXT) at each frequency point.
Power Sum NEXT (PSNEXT): Computed for each pair by calculating a power sum total of the pair- to- pair NEXT from the three other pairs.
Power Sum ELFEXT (PSELEXT): Computed for each pair by calculating a power sum total of the pair- to- pair ELFEXT from the three other pairs.
Power Sum ACR (PSACR):The ratio of the measured attenuation and the computed power sum near end crosstalk (PSNEXT) at each frequency point.
Equal Level Far End Crosstalk (ELFEXT): Measures far end coupling between pairs in the tested cable, for all pair combinations.
WireMap: Testing for proper termination of cables.
Length: Measurements determine the electrical length of cable runs up to 1100 feet
Propagation Delay and Skew: The Propagation Delay test measures the one-way propagation delay over each pair of the tested cable run. Skew is the difference in propagation delay between the pairs with the longest and shortest delay in a cable.
Return Loss: Measures the degradation of signal over all four pairs from each end of the tested cable run.
Attenuation: Measures the decrease in signal strength over the length of all pairs in a cable.
Near End Crosstalk (NEXT): Measures near end coupling between pairs in the tested cable run, at both ends of a cable, over 6 pair combinations.
