Very high-speed digital subscriber line (VDSL) is a cost effective solution for the last mile of the network over the existing twisted-pair telephone lines. The target of the VDSL system is to raise the transmission data rate up to 52 Mbps for short distances (300 m or less). This paper investigates the throughput of a DMT-based VDSL system at high sampling rates under the influence of various noises/interferences. The throughput limitation of the VDSL system is discussed and the optimal solutions of the sampling rates under various test loop lengths and environmental conditions are also investigated.
