This has been one item on my “mysteries of life” list ever since Verizon installed FIOS fiberoptic lines to each home in my neighborhood maybe 15 years ago. I stood there watching, probably with my mouth agape, wondering how they do that. Clever tech. Great video!
My neighborhood underwent a day without water a month or so ago. I thought to ask the poor contractor which company was involved. Long story short: I got 1G fiber in the house today. (:
My nearly-symmetrical bandwidth now exceeds the capacity of my router, as far as I can tell. The hardware installed is capable of 5Gbps symmetric, and that is expected to be available soon.
My middle son is a pipeline engineer. A few years back he explained how this worked when we drove past a crew using this to lay a pipeline under the section of I-45 we were on. He recognized the equipment and told me what they were doing and how.
