Crazy that you can splice optical cable..

They actually have very cool devices that will automatically align and fuse two fibers and estimate the loss of the bond. https://www.youtube.com/watch?v=JP_C0XLLyR0

how much do one of those bad boys cost?

One important question that I'm unclear on is how long it takes to fix one of these cables. If it takes months then that is quite a wide window in which an attacker could incrementally take down cables.

Generally it can be fixed in days. They raise it from the sea floor and splice in a new cable section.

True but ships and crews with the equipment to do the repairs are limited. It's possible to overwhelm the repair capacities. Also, it takes time to physically travel between cuts so while cuts in the Baltic might take a week or two to fix, a cut in the Atlantic and one in the Baltic may take a week or two just for travel.

The cheapest ones are surprisingly cheap at less than $1,000 and the highest end ones are $10,000

If someone will try to overwhelm the repair capacities for integral communications, they'll be dealt with like pirates - simply sunk and be done with.

As if they know which ship did this…

They already know. The captain will probably end up in prison for a long time, and company which owns the ship will pay for the deliberate damage. Would be good too if they can crack who from the crew works for Russian saboteurs besides the captain. Unlikely it's just one person.

Certainly worth blowing up some russian ships to make sure it doesn't happen again

How would blowing up Russian ships stop Chinese ships doing it again?

And then once they are fixed take them out again

> once they are fixed take them out again In an actual war, you hit the repair equipment and personnel [1]. (As to the Geneva Conventions note, we're discussing a hypothetical war with Russia. The status quo , including rules of war, are going to be rewritten by the victors.) [1] https://en.wikipedia.org/wiki/Double_tap_strike

If you are planting one cutting device (small bomb etc), you could do the same thing 10 miles down the line and blast it again without having to revisit the area.

They could even blow up all cables at once. Maybe the explosives have already been placed.

With timers ? because undersea communication is not as solved problem AFAIK
