Compared to VDSL, the latest change to the VDSL standard offers a significant increase in the potential data rate.
With what is known as Supervectoring (also called: Vectoring+, Super Vectoring or Supervectoring 35b), the transmission frequency on existing copper lines after vectoring is significantly increased again. Speeds of up to 300 Mbps are possible.
The following figures illustrate the difference between VDSL without Vectoring, VDSL with Vectoring, and VDSL with Supervectoring:
The graphic shows a normal VDSL connection. The data stream from a main distribution point is transmitted via fiber to a distribution box and then transported (for example) to households via copper cable.
The scenario is unchanged. Here, too, the data stream from a main distribution point is transmitted via fiber to a distribution box and then transported (for example) to households via copper cable.
Compared to normal Vectoring, Supervectoring increases the frequency spectrum from 17 MHz to 35 MHz. Especially over short distances, this results in a significant speed gain of up to 300 Mbps between the distribution box and the router.
Apart from the conversion of the distribution boxes, end users wishing to use Supervectoring need the correct router at their connection.
