tl;dr: drones can be tethered by fiber optic cables. The cable provides jam-proof communication between the drone and the operator; and it also supplies power to the drone so it doesn't need a massive battery pack and can stay airborne longer.

Fiber optic cable can’t supply power.

They could if it was a copper wire, but then it’s even heavier.

According to the article:

In the case of drones, the fiber optic cable provides a direct, stable, and high-capacity link for both power and data transmission. [...] The fiber optic cable also supplies power to the drone, meaning the UAV doesn’t need a huge battery onboard.

Maybe this is why we shouldn't have AI write articles. Does the drone have a solar panel on the other end of the cable?
