Explanation: A worst pair legrosszabb párként fordítandó, amint az a `worst pair method alábbi magyarázatából világos:
"PAIR-TO-PAIR" OR "WORST PAIR" METHOD ANSI EIA / TIA 568-A directs that cables with less than 5 pairs under a common final jacket use the "worst pair" method of evaluating crosstalk. In general terms, a signal is injected into one pair and the energy coupled to each of the other pairs is measured and recorded. This procedure is repeated until all pair combinations are evaluated. For example, a four pair cable requires six measurements to evaluate all pair combinations. A 25 pair cable requires 300 measurements. The cable's crosstalk performance is the result (expressed in dB) from the pair combination that displayed the highest energy transfer ( i.e. the poorest crosstalk performance).
Worst pair margin tehát lehet: a legrosszabb pár által támasztott korlát, és a megrendelőtől érdemes megkérdezni, hogy zárójelben nem lenne-e esetleg ajánlatos feltüntetni az angol kifejezést.
Enhanced Category 5 vs. Installed Base Category 5 Cabling
Enhanced Category 5 cabling provides additional NEXT margin (sometimes referred to as headroom in the industry) over the specified frequency band from 1 MHz to 100 MHz. The total noise power with all pairs energized, usually specified as Power Sum NEXT, meets or exceeds the Category 5 specification for worst pair-to-pair NEXT. This means that system designers can take full advantage of the 100 MHz bandwidth using parallel transmission on all 4-pairs in the cable without incurring a noise penalty. In addition, enhanced Category 5 cabling provides improved Equal Level Far-End Crosstalk (ELFEXT) and Return Loss performance.
