Fiber optic cables can freeze like this
The short answer: No, fiber optic cables themselves don't freeze in the same way water or metal does. Fiber optic cables are engineered with robust protective layers that make them resilient to cold temperatures. Fiber optic internet connections are more popular globally because they provide various benefits over regular. Freezing and thawing cycles can cause moisture to penetrate poorly sealed cables, leading to potential damage when the water freezes and expands. If water has the chance to enter into. Optical fiber must be robust enough to cope with being run between communications masts for telecoms links, across freezing ground for television outside broadcasts, and alongside roads to carry video from traffic cameras.
