Agreed 100%. This article, like so many others, has personal opinion mixed up with and
asserted as facts, and most readers aren't in a position to examine and extract the
valid points from within the emotive and invalid points.

The year-on-year running and maintenance costs of a fibre access network should be
significantly lower than the costs to run and maintain the copper network - but this
is somehow never mentioned. I used to know how much Telstra spends on replacing air
gas bottles used to pressurise main cable jackets to try to keep water out, many of
which leak like a sieve - not to mention the labour cost of guys running around every
day with truckloads of gas cylinders - none of which are needed for optical fibre cables.
Similarly the power required to drive a signal down fibre is milliwatts, compared to
1.2W or so required to deliver a DSL line.
Nobody seems to be factoring the lower annual running costs into the TCO comparison -
which was one of the main reasons Telstra gave for wanting to deploy the FTTN network
in the first place.

Rubbish - the bulk of the capital costs are the civil construction required to install
the optical fibre cable. The network equipment lighting up the fibre is peanuts in
comparison, and is usually replaced to achieve a performance or capacity increase of
several hundred percent, reducing the overall per-unit cost of the network even further.
Didn't bother reading further after finding that paragraph.
