Damn, how big is a 41km spool of fiber optic cable?
https://www.amazon.co.uk/Jeirdus-Launch-Singlemode-Measuring-Optical/dp/B07H5J2T5G
About 1500 EUR or USD. It´s a spool 15cmx15cmx12cm, 1 kg. 6inx6inx5in, 2 lb for the metric impaired.
That's impossible. How can it be that small?!? They list the same dimensions regardless of which size spool you choose.
I work in telecommunication and see fiber quite regularly.
It really is thin, and fine is a better word. In general what you see is the coating of the fiber, and that already is very fine. The fiber itself is nearly invisible even when you hold a strand between your fingers against the light.
A single of these nearly invisible fibers can transport a GBit/s into your home. “Any sufficiently advanced technology is indistinguishable from magic” - yep, Arthur C. Clarke was right.
