Very High-speed Digital Subscriber Lines (VDSL)

Very high-speed digital subscriber lines (VDSL) are extremely high-speed digital subscriber line (DSL) connections over short distances. VDSL offers speeds from 13 Mbps to more than 100 Mbps over distances of between 1,000 and 4,500 feet — the shorter the distance, the higher the speed. VDSL comes in both asymmetrical and symmetrical flavors and in different configurations. Most advanced VDSL deployments use VDSL2, which promises up to 100 Mbps bandwidth. We account for all VDSL technologies together in our generic VDSL (VDSLx) category.
