Berk-Tek's LANmark 1000 cable is one of the industry's first cables to be fully characterized for complete power sum performance including power sum near-end crosstalk
(PSNEXT), power sum attenuation-to-crosstalk ratio (PSACR) and power sum equal-level far-end crosstalk (PSELFEXT).
PentaScanner 350 comes with the 2-Way Injector for measuring Near-End Crosstalk
(NEXT) from both ends of an installed cable.
PowerSum NEXT is a measure of Near-End Crosstalk
to ensure proper operation of networks employing simultaneous transmission on more than one pair in a channel or link.
The 2-Way Injector+ is an accessory to the PentaScanner+ that measures Near-End Crosstalk
(NEXT) and Attenuation-to-Crosstalk Ratio (ACR) from both ends of the installed network cable link which saves installation time.
NASDAQ/NMS:MTST) Thursday announced the 2-Way Injector(TM), an accessory to the PentaScanner(TM) that measures Near-End Crosstalk
(NEXT) and Attenuation-to-Crosstalk Ratio (ACR) on both ends of the installed network cable link.
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.
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
now provides a much higher data rate (over 500Mbps over copper) than legacy VDSL systems (100 Mbps), TDD architecture with configurable uplink/downlink ratio, advanced FEC, automatic retransmission, NDIM technology for interference mitigation and automatic mitigation of Near-End Crosstalk
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.
