[LINK] Anticipated service life of fibre

[Marghanita da Cruz]

Hi Andy,

It is a risk - I have seen the cables being pulled from buildings which 
are to be demolished.
In the 1980s, the catchcry was to future proof buildings with optic 
fibre. I wonder how much of fibre pulled out of buildings has never been 
used.

The question is whether you run a fibre optic along a 
sewer/electricity/water/gas duct or pole, just in case,  or pull this 
through later (as is being done with the NBN).

My front garden has an electricity wire running over it, telstra copper 
line on the eastern side and water across the front and up the western 
side and gas on the western side!
Storm water on either side and Sewerage on the Western side. I will 
grant that much of this dates back to the late 19th century - so, I am 
not even sure Dial before you Dig will work!
