Analýza parametrů sdělovacích kabelů SYKY a SYKFY

Abstract

The aim of this bachelor thesis is to prepare technical documentation for all cable conductors in the Transmission Systems and Media Laboratory in the frequency range up to 2.5 MHz. These are SYKY and SYKFY cables with lengths of 500 meters and 1000 meters. The parameters of these cables will be further compared with the catalog values and the ITU-T Recommendation G.996.1. The characteristics impedance of these cable lines was calculated as the geometric mean of the input impedances at short and idle conduction. A seven-parameter British Telecom model was used to model the primary parameters of the line. The resulting values determined line parameters are within the tolerances specified by the manufacturer, the differences from the ITU-T G.996.1 are described in further work
