      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.

          If you can inject commands into a communication line, somebody was really stupid while designing it.

            Which happens, but then a different idiot tends to fix it. See what happened with the Starlink-controlled drones.

            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).

                no, because often its not “internet/network over fiber” stuff but HDMI over fiber no ip there. HDMI cables have very limited lenght due to high frequency beeing used in em, so if you have a media production company and a few spread out cameras HDMI over fiber is kinda common

      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
