Not particularly. Fiber optic cables are immune to any damage from electromagnetic interference, which is a significant advantage over other cables used for internet service and other purposes. Fiber optic cables are often involved in systems that work with electricity but do not conduct electricity themselves. No heat or visible light comes off of them, so they are usually safe and more likely to get damaged from getting bent or physical means rather than electricity. People working with them need to remain cautious and not look directly at them or risk eye damage.
