Supervectoring

Next-generation VDSL

What is Supervectoring?

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.

How does Supervectoring work?

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 problems of VDSL without Vectoring:

A copper cable contains several smaller copper cores that are not shielded from one another
Interference between the copper cores impedes the data transmissions
Reception may be difficult
The bandwidth and range of the signal transmissions may be limited

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.

Difference with Vectoring:

Special DSLAM (Digital Subscriber Line Access Multiplexer) in the distribution box
Measurement of interference in the copper cable and the individual copper cores
Sending an anti-cyclic signal to neutralize interference on the line
Downloads at up to100 Mbps

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.

New with Supervectoring:

Increased frequency range from 17 MHz to 35 MHz
Significantly improved performance with downloads at up to 300 Mbps
