EVALUATION OF DIGITAL SUBSCIBER LINE TRANSMISSION RATE USING G.FAST TECHNOLOGY

Abstract

Evaluation method of uncompensated crosstalk when using the "vectoring" system is improved. The practical measurement results of the frequency characteristics of the ТППэп-10х2х0,4 cable in the frequency range up to 100 MHz are presented and their approximation is performed, the results of which were used to study the characteristics of the G.fast technology transmission system. Impulse response of the G.fast TS transmission channel length of up to 150 m from the secondary parameters of the ТППэп-10х2х0,4 cable is determined and for the interference distribution on G.fast TS channels is calculated. Achievable transmission rate of G.fast TS when working on multi-pair telephone ТППэп-10х2х0,4 cable considering interference and crosstalk, and using "vectoring" compensation crosstalk system is estimated.
