seems like this would have to be very short range. Fiber optic cable weights 752 kilograms (1757 lbs) per kilometer. Not sure if that weight is for a single strand or an average sized cable with many strands.
A single strand weighs about as much as 30lb test fishing line.

What is used for these devices is certainly not the robust multithread fiber optic cable we use domestically. Such cables are designed for long term use and have all sorts of “armor” and moisture protections built in. It would only make sense to use light weight single tube thread only suitable for a single mission. In other words I suspect it would be even more “expendable” than the drone it serves.
