What? Why is there so much fiber optic cable?

[–] Fandangalo@lemmy.world 52 points 2 days ago (3 children)

From Internet (not op):

Fiber-optic first-person-view drones areΒ jam-proof. Sending and receiving signals along millimeters-thick but miles-long optical fibers, these FPV drones are impervious to the radio interference that can ground wireless FPV drones. That doesn't mean it's impossible to defeat a fiber-optic drone.

So that's where all of the USA's fiber rollouts ended up

Just need sissors and a pogo stick to bring one down.

Russians can just mark their location to make it easier.

Are they tethered to the operator?

[–] nimble@lemmy.blahaj.zone 30 points 2 days ago* (last edited 2 days ago) (1 children)

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:

[–] NOT_RICK@lemmy.world 4 points 2 days ago (3 children)

Now I’m curious how much a 40km long spool costs

[–] BastingChemina@slrpnk.net 5 points 1 day ago

Looking at Alibaba, the "bare fiber for FPV drone" cost around $600 for a 50km spool.

[–] _cryptagion@lemmy.dbzer0.com 6 points 2 days ago

Just several hundred dollars, and a visit from the ATF.

[–] FundMECFSResearch@lemmy.blahaj.zone 2 points 1 day ago (2 children)

Very expensive probably. They are selling 1000 feet (I think that’s like 300m) on Amazon for between 300-900 USD.

[–] Tire@lemmy.ml 2 points 1 day ago (1 children)

Still way cheaper than the $58k it costs for a switchblade drone.

[–] FundMECFSResearch@lemmy.blahaj.zone 0 points 1 day ago* (last edited 1 day ago)

If you take the amazon price as reference. It comes out about the same when adjusted for length, maybe slightly more expensive.

[–] LonstedBrowryBased@lemm.ee 9 points 2 days ago

The drones are fly-by-wire
