I wonder how much 40km of fiber optic cable costs?

[–] [email protected] 11 points 21 hours ago

Less than a Javelin Missile.

SM fiber is dirt cheap, they don't need to wrap it in kevlar like you'd find in data centers ironically enough, it's just a strand or two of thinly jacketed single mode fiber.

Only has to survive the one flight, be light enough and long enough.

Cheap fiber is about $0.40/m.

What does fiber optic mean in this context? Like a fiber optic cable attached to the drone for communicating with it?

[–] [email protected] 14 points 22 hours ago

Yup. Fiber optics can't feasibly be jammed. The drone is still powered by battery, but is controlled over a fiber that is spooled in the canister on the bottom.
