VDSL2 reaches 0.5Gbps
While fibre can vastly exceed speeds of 0.5Gbps (500Mbps), there are many parts of the world (including the UK) where full fibre to the premises will be outnumbered greatly by the deployment of cabinet based solutions.
VDSL2 is the current candidate for any FTTC product from Openreach, and for telephone lines that are just 0.5km long from the green street cabinet to the home speeds of 100Mbps are possible. Ericsson has announced the first live demonstration of bonding together six lines all 0.5km long to produce a 0.5Gbps connection. At first this sounds simple and straight forward, but to get the most from bonding management of crosstalk needs to be carried out, and Ericsson used Vectoring which reduces noise from other VDSL2 lines in the cable bundle and potentially reduces power consumption.
For those keen to read more cellular-news.com has more on what Ericsson achieved, with VDSL2 bonding being suggested as a solution for providing backhaul from mobile phone cell towers.
