This caused a bit of a double take. I thought that fibre was used in
intrinsically safe environments precisely because of a lack of a fire
ignition risk if the cable breaks. Surely there isn't enough energy from the
photons emanating from a damaged fibre? Do you have a source for your
proposition? (Before I spend hours digging through the web myself)?
I don't know that this is wrong, I'm just surprised that it could be right.
NTT has been pulling fibre though Japanese POO (Partitioned Optical
Operations 8^) ) for over 10 years. When I worked for Fujitsu, circa 1988, I
remember seeing a video of their little robots pulling fibre through Tokyo
sewers. In fact, 5 years before that, Exxon was pulling fibre through their
oil pipelines in the Gulf of Mexico. At Esso, we investigated that for Bass
Strait but decided the re-engineering of the pigs would cost too much. Used

The sewer is, I suspect, a very inappropriate environment for fibre ... not
because of what the poo might do to the fibres, but because of what the
might do to methane should a fibre break.
eg, fibre is still used only with caution in some mining applications
the risk of explosion...
