Cold temperatures affect fiber optic cables when water enters the ducts transporting the wires and freezes. Here's how cold weather can. One specific problem is how the fibers and connectors cope with sub-zero temperatures. When the temperature dips below freezing, water freezes, and ice develops around the fiber, causing it to distort and bend. This. Optical fiber transmission has the advantages of wide transmission frequency, large communication capacity, low loss, no electromagnetic interference, small diameter of optical cable, light weight, rich source of raw materials, etc., so it is becoming a new transmission medium. Another solution can be to add.
