Supervectoring

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:

VDSL without Vectoring

VDSL-without-Vectoring

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

VDSL with Vectoring

VDSL-with-Vectoring

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

VDSL with Supervectoring

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.

VDSL-with-Supervectoring

New with Supervectoring:

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

The LANCOM Supervectoring portfolio

Apart from the conversion of the distribution boxes, end users wishing to use Supervectoring need the correct router at their connection. The upcoming LANCOM 179x series will be able to take maximum advantage of the additional bandwidth.
