Are they tethered to the operator?
The drones have a spool of fiber optic cable. Some spools can reach 40km. The spool unwinds as the drone flies and yes it would either lead back to the operator or they could in theory have a node that it connects to and then from there connect to operator via cable or wireless. Really fascinating stuff imo
How they work:
Now Iβm curious how much a 40km long spool costs
Looking at Alibaba, the "bare fiber for FPV drone" cost around $600 for a 50km spool.
