Výkonostní testování intergrity heterostrukturní telekomunikační sítě

Abstract

The aim of this thesis is to build a herostructural network consisting of optical and metal parts. The optical part is represented by EPON and xWDM. The metallic part consists of the ADSL2 + and VDSL2 systems. After connecting these parts into an unified unit the series of tests were performed on the network in combination with inserted line and noise for subsequent deployment of Triple Play services. The theoretical part deals with optical access networks. Especially passive optical networks PON with older and new generation. Furthermore, the issue of hybrid networks is discussed. The next part is dedicated to xDSL technologies and the best known variants. The theoretical part is completed with a description of Triple play services. Practical part deals with building of heterostructural network, which is analyzed using RFC 2544, RFC 6349 and ITU-T Y.1564 tests. Furthermore, practical part contains measurement results, which were performed on individual parts of the network. For example chromatic dispersion, polarization mode dispersion, attenuation, power level for optical part and transfer rates of ADSL2 +, VDSL2 for metalic part were measured. At the end there were services like Triple Play (IPTV, VoIP, Data) deployed on heterostrucure network and the influence of quality of communication was examined depending on line length with added noise.
