VDSL2 is the fastest xDSL technology at present. Its data rate is variable depending on the length of wire and generally higher than HDSL and VDSL. VDSL2 uses the original POTS hardware to provide up to 100 Mbps data rate in upstream and downstream. The disadvantage of VDSL2 is that the longer the transmission distance, the lower the data rate. Generally speaking, the transmission distance is typically less than 1200 meters. The VDSL2 modem in this research is based on Infineon chip set composed of PEB83000 and ADM5120 with an operating band up to 30 MHz. The data rate in the different profiles of chip set is compared to find the optimum performance for a certain transmission distance.
