Well, I think potentially it can definitely affect the fiber optic cable. One particular problem connected with it is how the water can make its own way into the conduit or even dust carrying the fiber. It has been told much about the potential effect, so I would better concentrate on the solutions. To alleviate the risks, one and only way is to install fiber cables buried below the frost line. But this method would be very expensive for sure. Besides it, it's hard to follow when fiber cables should be routed along a bridge or other structure. Another option is to add antifreeze liquids to the fiber conduit. Again, it's not a cheap enterprise. So, you would definitely better contact a
