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. According to this standard, the bandwidth was doubled from 17 MHz to 35 MHz, the transmission power was increased at high frequencies, and the Far End Crosstalk( FEXT) was reduced.

VDSL2 specifications with vectoring

By doubling the bandwidth and transmit power and reducing 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 Mbit/s. In the uplink, the data rate is 40 Mbit/s.
