Fiber optic cable blown down by the wind
High winds and flying debris can break aerial fiber lines, while ice accumulation can weigh down and snap cables. Fiber offers several benefits over traditional copper-based internet, including faster download and upload speeds, lower latency, and better reliability. But, just like any other technology, it can fall prey to outages due to numerous factors, including weather conditions. Fiber optic cables, though often encased in protective sheathing, are nonetheless. While wind itself doesn't directly impact the signal transmission through modern fiber optic or cable lines, its indirect effects can lead to significant connectivity problems.
