Abstract
Mathematical models of the «vectoring» crosstalk compensation system for TPP-50х2 and TPP-100х2 multi-bundle telephone cables are developed. Simplified calculation formulas for the total power of the far end crosstalk and the crosstalk suppression by the «vectoring» system at parallel operation of xDSL-systems on the bundle twist cables with the number of bundles up to five are defined. Spectral power density level of the crosstalk ratio at the receiver’s input of the transmission systems on VDSL2 technology without and with the «vectoring» system application is estimated depending on the signal frequency and the line length when TPP-50х2 and TPP-100х2 cables are fully loaded with the transmission 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 with parallel operation of the VDSL2-systems on the domestic multi-bundle telephone cables TPP-50х2 and TPP-100х2 with up to 500 meters line length.
