I posted this OC 8 months ago, today i see this in my YT feed:

Well done.
I didn’t think fibre optic cable worked like that.
On the case of the real drone, the laser is destroying the cable.
On the OP’s case, yes a laser can interrupt the communication. But the drone needs to keep sending it, or the drone will just continue after it’s gone. On the other hand, you need less power.
unless it injects a detonation command
If you can inject commands into a communication line, somebody was really stupid while designing it.
Well those fiber optic line end points are not exactly encrypted, they use off the shelf components like HDMI over Fiber adapters, and serial over fiber for control link. In rare cases they could maybe use a actual IP connection over fiber but i doubt that since, it would add overhead, latency and make the hardware setup a lot more complex and expensive (if would be able to encrypt tho).
The fibre that’s carried by combat drones is uncoated, so with the right angle it’s possible to inject another signal.
We still don’t know the full story, it was probably a drone flying rounds trying to detect fiber optic and something else cut the cable, there’s no way you’re powering a 5kW laser off a quad
edit: even if it’s tethered, which isn’t a real thing yet
