Enhanced EMI shielding and low near-end crosstalk (NEXT).
The high-channel-count capability of the DCA-TDR solution also helps to minimize cable reconnections and facilitate more efficient near-end crosstalk and far-end crosstalk measurements in both R&D and high-volume test applications.
In this model, near-end crosstalk characteristics were also studied using the cascading technique and compared those with other results to show that the cascading technique cannot efficiently estimate crosstalk because discontinuity effects are not considered in the technique.
Near-end crosstalk ranges from -40 dB at 13 GHz to -57 dB at 4.
Since the overall coupling effect is the sum of capacitive and inductive crosstalk, near-end crosstalk is of greater magnitude, and hence, of greater concern for a PCB designer.
The transceivers are required to cancel both echo and near-end crosstalk (NEXT) on each pair of wires, and cancellation of far-end crosstalk, while recommended, was not required.
005" thick, the saturated near-end crosstalk coefficient (NEXT) in broadside coupling is about 15%.
The MystiPHY110 offers high immunity to noise and cross-talk, meeting the IEEE specification for near-end crosstalk (NEXT).
The GigaSPEED XL 2081 cabling also transmits voice, data and video with a guaranteed margin of 10 db near-end crosstalk (NEXT) and power sum NEXT.
NEAR-END CROSSTALK in a transmission line bus can often exceed the allocated noise budget.
Patch cords can be tested for one-way return loss, one-way near-end crosstalk (NEXT), propagation delay, and length and delay skew.
