New undersea cable tech listens for sabotage — can be retrofitted to existing fiber optic lines
This tech adds sonar sensing to fiber optic cables.
IDC I'm still going to sabotage it.
Really cool tech and simple tech, tldr, it uses acustics to detect even light touches in the cable; basically it turns cables into guitar strings.
As for sabotage, I don’t know, you could infer what boat caused it maybe? Like the Russian sabotage at the beginning of the war with Ukraine? Doesn’t seem to be much data other than, hey something is touching the cable.
Gonna detect a lot of sharks in that case https://slate.com/technology/2014/08/shark-attacks-threaten-google-s-undersea-internet-cables-video.html
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)
Sabotage by the Deepsea Boys?
I wonder if they can do much with the information other than go “yup cable was fiddled with somewhere on the length of the ocean floor”.
Knowing when the touching becomes instead of when the connection cuts is a big improvement in any case
