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
