Seen in the test lab: 46Mbps/4.8Mbps pair bonded ADSL2+


This week we have demonstrated ADSL2+ connection speeds of 46Mbps downstream and 4.8Mbps upstream. Our network design team achieved this speed in the lab environment, on a short copper loop.

Because of longer loops and interference, this is not a speed that we will see in the real world, but it is very exciting to see the full potential of ADSL2+/Annex M.

Today we have staff with real world loops running at over 30Mbps, so that is a more realistic goal.

Two pairs of telephone wire were used in the test to deliver a bonded (double pair or four wire) ADSL2+ link, with Annex M (double upstream) capability turned on. Actual FTP transfer speeds were demonstrated at over 42Mbps upstream and 4.5Mbps outbound after overhead.

We are working on the wrap-up of product design and pricing for our new pair bonded Fusion products, and we plan to announce the details shortly. Fusion Broadband continues to bring customers innovation in Internet access.
