I found the document in the Internet Archive:
"Senator McEWEN—Just on the same issue, there are claims made that fibre
technology does not have a life long enough to guarantee a return on
investment. Can you make some comment about that, Mr Quigley?
Mr Quigley—Yes, I have heard those. I have had the same debates with
some of the media, who simply, as I said before, are not particularly
interested in the facts on this issue. It astonishes me, to be honest,
given that we are seeing huge increases worldwide in fibre deployments.
Companies such as AT&T, Verizon and DT, all throughout Asia, are all
deploying fibre. We speak to the manufacturers of fibre. They simply do
not know how long the fibre will last because they can see no mechanism
by which it would degrade—unlike copper, which is metal and which is
carrying current. There is a natural tendency, then, to get levels of
corrosion. This is glass. It is inherently stable. It is strengthened.
Clearly if somebody puts a spade through it, as through a piece of
copper, they will break it. But there is no inherent reason why this
fibre should degrade over time. It is very, very stable. So there
have been lots of reports about a 12-year life. I do not know where this
data is coming from, but it certainly is not supported by the evidence
we see overseas and not supported by any of the people who should know,
who are the fibre manufacturers.
Senator BIRMINGHAM—So you cannot put a lifespan on it at all?
Mr Quigley—I could not, frankly. I cannot put a lifespan on it. Some of
the copper network, by the way, has been in the ground for 50 to 60
years and is still providing service. It is getting more and more
expensive to maintain. It is very difficult to put a lifespan on it. It
would be at least 30 years."
