A Series of Tubes #56 — Can ADSL2+ and the NBN get along?
July 9th, 2008Probably the silliest urban myth surrounding Fibre to the Node (FTTN) is the idea, promoted in some national newspapers, that optical signals interfere with electrical signals. However, there is a problem: the VDSL-based network proposed to connect nodes to homes can cause problems for ADSL2+ services from the same exchange – and ISPs fear that their ADSL2+ investments will be stranded by the NBN.
In A Series of Tubes, Richard Chirgwin talks to ADSL standards expert Dr Paul Brooks of Layer 10 Consulting, about whether VDSL and ADSL can co-exist.
