You forgot about one very important element of the fiber optic cable - the hydrophobic gel filler. The glass used, oddly enough, is very easily destroyed by water. The fibers are bathed in gel so that water cannot approach them. By the way, an ordinary laser pointer is visible at a distance of more than 2 km in optical fiber. I conducted such an experiment. :)
We have similar effect with the sound here. My grandfather used to say that when we hear the train from the next valley behind the small hills, the weather is going to change. It happens only a few times in the year, otherwise you don't hear the train at all. And it's not the wind, or not only. When that happens we have 'thermic inversion', in the hills is warmer than in the valley, it's common in the mediterranean in winter. But usually after that it gets colder.

👍🏻👍🏻👍🏻😉thanks for sharing your expertise.

How do I watch these videos in order? I want to watch all of them.
