VDSL2 and G.fast connections are designed to deliver new services via symmetrical copper pairs and fiber optic in access telecommunications networks. VDSL2 connections follow the older ADSL technology and bring to subscriber higher transmission speeds. In addition, symmetry and optimization of transmission speeds for upstream and downstream are allowed. Nowadays VDSL2 connections and G.fast are latest evolutionary steps in xDSL technologies and their implementation to access telecommunications networks are also part in the concepts of FTTx networks.
The material introduces the principle of VDSL2 connections and G.fast, possible variations, used modulation and coding. The achievable transmission rates and the possibilities of connection of the new generation of xDSL are presented. The basic knowledge of the properties of telecommunication lines and basic methods of digital transmission and signal processing in studying this module are expected.
