Because fiber-optic cables use light rather than electricity as a transmission medium, fiber internet is immune to the effects of electrical interference from storms. Workers often put cables underground, and sometimes they use jackets that block UV rays to protect them. Special seals and tough covers keep water out. These features make fiber a very good choice for internet, as it works well even when. The short answer: Fiber handles weather better than copper or satellite because it carries data as pulses of light instead of electrical signals. Cold isn't the real threat: The glass strands rarely freeze, but moisture that seeps into connectors can freeze and cause damage. But, just like any other technology, it can fall prey to outages due to numerous factors, including weather conditions.
