I am doing a Pluralsight course - Designing Cisco Enterprise Networks: WAN for Enterprise Networks - and it mentioned a little something called Dark Fibre. That's a new term for me, and maybe for you as well. Let's research it. Dark Fibre is a bit of unused optical fiber. One can make a private fiber network with this, as it sounds like the dedicated telephone lines that companies can buy to connect sites that are miles apart. It has great potential for capacity . There seem to be many unused fiber cables out there, buried underground, as telecom companies apparently bought too much. They may not sit unused for long, however, as with increased internet demand these days, content creators are demanding it.
I research and implement products + infrastructure for the Cloud, software, and other interesting things. My tailored Cloud Project Portfolio is at runtcpip.com
