The parameters that are tested for CAT 6 are the same as for Enhanced CAT 5, except that the performance limits of attenuation, pair-to-pair NEXT, power sum NEXT, ELFEXT
, power sum ELFEXT
and return loss, are more stringent, and the testing frequency range of CAT 6 is 250 MHz--more than twice that of enhanced 100 MHz.
OMNIScanner provides accurate return loss and ELFEXT
measurements for 1000Base-T networks.
The LT 8600 is a high-performance tester that has Level III accuracy, two-way return loss, power sum NEXT, ACR & ELFEXT
, and identification of distance-to-fault tests.
When used with next-generation cable, Giga-Channel provides channel performance exceeding proposed Category 6 requirements, including power sum NEXT, power sum ELFEXT
, attenuation, and return loss.
CyberLAN-5E cable is third-party verified to currently proposed ANSI/ TIA/EIA specifications that add performance parameters such as Power Sum NEXT, ELFEXT
, and Return Loss.
