While fiber optics are tough, cold temps can cause trouble. Water in cables can freeze, potentially harming connections. Waterproofing prevents icy issues. There are three common types of fiber connectors: SC, ST (bayonet-twist) and LC (push-pull locking). The LC connector is most commonly chosen, because it is much smaller than the other two, and also provides a secure clip connection. Unfortunately, the standard LC connector does not provide. The short answer: No, fiber optic cables themselves don't freeze in the same way water or metal does.
