super vectoring

Supervectoring is a further development of VDSL2 and vectoring that increases downstream and upstreamdata rates

many times over. The ITU has specified supervectoring in the ITU-T G.993.2 standard. It then doubled the bandwidth from 17 MHz to 35 MHz, increased transmission power at high frequencies, and reduced Far End Crosstalk

(FEXT).

By doubling the bandwidth and transmit power and reducing the FEXT, the data rates of supervectoring could be increased from 100 Mbit/s to 250 Mbit/s over a line length of 500 m in contrast to normal vectoring in the downlink. Over a line length of 800 m, the download rate is 100 Mbps. In the uplink, the data rate is 40 Mbit/s.
