[AusNOG] "The NBN" will run on copper for *ever*

[Grahame Lynch]

Indeed John. Clearly Alcatel Lucent wouldn't be wasting their time
commercialising something which would be unusable in the real world. The
key point isn't the peak speed in the optimal environment - it's the simple
reality of what comes behind that, better speeds at longer runs. The key
here is Alcatel's "small nodes" which serve neighbourhoods of a couple of
score of houses serving short runs of copper. As long as they can keep the
overall cost of the solution well below a turn-key FTTH civil excavation
there will be markets for this across the world.
