There is fucking light going through it. For fiber you know the second somebody breaks it. You can even see the timing of fibers breaking in sequence. This does not change the fact the cable is broken and needs repair.
As for others splicing into it: same shit. You always know exactly the distance to the next point of contact, so you also got that.
Wtf is this shit other than trying to sell something to the news?
You get to know faster, not when it cuts but when it begina to be cut.
If it's not instant they can estimate who was better I guess.
You can hear to some level, the boats and actions in the vicinity of the cable. So it might provide evidence in case of a break.
It also lets you know if the cable is moving round on the seabed etc, this is useful as it can cause wear.
I seem to remember it being used to check the health of power cables too (they have fibre cables embedded within them)
