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.

Crazy that you can splice optical cable..

I mean… they get terminated somehow, right?

True, but splicing without leaving behind a powered repeater is different from the final termination with active electronics on the end.

It's pretty cool tech

I’m saying you can terminate cleanly without needing a repeater.

To be clear, I’m saying to terminate each end of the cut cable to a terminating device that continues the flow of light, not just the termination at the beginning/end of the line. Sorry if that wasn’t obvious.
