On using LAN cables in FTTB/VDSL environment

This paper presents some results of research on possibility of using LAN (Local Area Network) cables instead of DSL (Digital Subscriber Line) cables in access networks. The aim of this paper is to answer the question whether (and under which conditions) LAN cables can be used as a replacement for DSL cables, and whether they can provide the same quality of service (QoS). CAT5e Ethernet cables and xDSL cables with diameter of 0.4 mm were used for measurements. The results were collected and compared for two different lengths of cables and for different loop conditions (good and fault loop). All results of measurements are collected on real system in operating conditions.
