Spotted the following in a news article ontelecompaper
Shows that vectoring is giving 100Mb over 300m and is being rolled out in the EU. It will be interesting to see when this is rolled out in the UK.
Huawei Poland announced completion of the final phase of work on its vectoring system, thereby enabling mass deployment. The system developed by Huawei can reach speeds of over 100 Mbps over a distance of up to 300 meters over a single copper pair. Copper cables in Poland are available in almost 100 percent of premises, office and residential. In 2009, Huawei presented a prototype of vectoring and carried out the first tests in collaboration with BT and Swisscom. However, the development of vectoring faced problems of compatibility with the older generation of subscriber devices operating in existing networks. To overcome this, Huawei has developed the Auto Sense Function that automatically identifies the user terminal equipment and thereby applies appropriate operation on the DSLAM. As of April, Huawei provided globally more than 1.2 million VDSL2 vectoring lines.
