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

does it destroy the actual glass cable, or does it get inside and travel along the optic path and burn out the transceiver? burning the glass to breaking point seems like it would take a heck of a lot of energy, so i assumed it was attacking the light sensors at each end of the line, but people keep saying it’s actually breaking the glass.
Well done.
I didn’t think fibre optic cable worked like that.
The fibre that’s carried by combat drones is uncoated, so with the right angle it’s possible to inject another signal.
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).
Now try to fit enough batteries to power that laser on a drone lol (spoiler: you can’t)
tethered
ok so the giant battery is in the tank, guess how big a cable would have to be? You’re not putting that on a quad
edit: it’s also impractical as hell to tether drones when most roads get netting installed over them, just saying
edit2: why not just put the laser on the tank? fry the drones around you directly instead of hoping you cut the comms in the fiber optic lines
It wouldn’t have to run at full power all the time, just when actively defending against a drone. There are lots of other harder to solve issues.
Ok and? Still needs batteries and cables to withstand peak power, still needs to be tethered somehow, still needs another crew member constantly flying it. Not to mention being this close to combat and to the ground, you better have some insanely good lens protectors or that laser is gonna be out of commission after any shrapnel lodges itself in.
Completely made up idea to counter this made up idea, but if you’re putting it on armor - a 12 gauge turret sounds so much easier. Doesn’t need a shitload of power, can put it onto a generic stand/turret base, targeting is easier and you’re guaranteed to ruin the enemy drone’s life
The laser could be on the tank with a mirror on the drone
Archimedes would love it.
guess how big a cable would have to be
I can show you a chunky 500W cable for a pc power supply, would be just as relevant. Look up cables of actual laser power supplies, they’re big and relatively dense, and we’re talking about tethering a quad, it’s not gonna fly well with that dangling.
This man has never heard of ohm’s law
Not a man but I take your point, consider that this drone and the cable is gonna get peppered like crazy. Plus you don’t want it tangling up
Apologies, I had meant “man” as person but I recognize that usage is dated. No gender assumption was intended.
