P&T Luxembourg is testing Alcate-Lucent’s Zero-Touch Vectoring innovations to help meet the government’s “Ultra High BroadBand”, which aims at providing all Luxembourg residents with broadband speeds of 100 Mbps downstream and 50 Mbps upstream.
P&T Luxembourg is already deploying Alcatel-Lucent’s GPON and P2P-based fiber access solution, and is now investigating how to leverage its existing DSL infrastructure to reach the government’s 100 Mbps target faster – through the use of VDSL2 Bonding and Vectoring.
VDSL2 Vectoring is a noise-cancelling technology that removes the interference between the multiple VDSL2 lines, so that each VDSL2 line can operate at its best and deliver higher data transmission speeds. In combination with VDSL2 Bonding, which takes two copper-based VDSL2 lines per subscriber and aggregates them, speeds of 100 Mbps can be achieved at distances up to 800m.

In October, lcatel-Lucent introduced new signal processing software developed by Bell Labs that promises to shake up the business model for VDSL2.
The new ‘Zero Touch Vectoring’capability eliminates the need to upgrade every CPE in a copper node whenever the first customer opts for faster broadband access delivered over a VDSL2 vectored line. Previously, a carrier choosing to deploy VDSL2 Vectoring was required to upgrade every modem on the network in order to properly handle the crosstalk elimination.
