Fiber optic cables for outdoor applications are engineered to withstand the more demanding conditions seen outside, from environmental extremes to mechanical forces.
These are the outdoor fiber optic cables you see strung along telephone poles (aerial), installed inside an underground duct, or even buried directly below ground. Rugged fiber optic cable is constructed so as to resist ultra-violet light and temperature fluctuations and may include features to withstand the requirements of being installed outdoors.
