Abstract

In this work the mathematical model of the “vectoring” crosstalk compensation system for TPP100x2 domestic multi-bundle telephone cables is developed. Simplified calculation formulas for the total power of the far end crosstalk and the crosstalk suppression by “vectoring” system in the parallel operation of xDSL-systems over the multi-bundle cables are defined. The crosstalk spectral power density level at the receiver’s input of the transmission systems on VDSL2 technology without “vectoring” system and with “vectoring” system application is estimated depending on the signal frequency and the line length for 10 % and 100 % loading of the TPP100x2x0.4 multi-pair cable by VDSL2 systems. The efficiency of the “vectoring” crosstalk compensation system application is estimated by the crosstalk suppression value in the frequency range of up to 35 MHz in the parallel operation of the VDSL2-systems over the domestic multi-bundle telephone cable TPP100x2x0.4 with up to 500 meters line length.
