VDSL 是传送速度最高可达数十 Mbit/s 的 DSL 技术。该技术主要面向办公室及公寓内金属线路的高速传输应用。2005年2月9日,VDSL(超高速数字用户线路)芯片组供应商美国 Ikanos 通信公司宣布开发成功上,下行数据传输速度均可达到100Mbit/s 的 VDSL 物理层 IC。虽然 VDSL 之前已经有下行传输速度150Mbit/s 的芯片组,不过,上行传输速度仍只为50Mbit/s。此次开发成功的 IC 可保证在100Mbit/s 的传输速度下,上、下行距离分别达到
VDSL is a DSL technology that delivers speeds up to tens of Mbit / s. The technology is mainly used for high-speed transmission of metal lines in offices and apartments. February 9, 2005 VDSL (Very High Speed Digital Subscriber Line) chipset provider Ikanos Communications announced the successful development of VDSL physical layer ICs with up to 100 Mbit / s downlink data transmission rates. Although VDSL had a chipset with a downlink transmission speed of 150 Mbit / s before, the uplink transmission rate was still only 50 Mbit / s. The success of the development of the IC can guarantee the transmission speed of 100Mbit / s, the downlink distance reached respectively
