Corning Optical Communications cable specification sheets are available which list the maximum tensile load for various cable types. The maximum pulling tension for stranded loose tube cable and ribbon cable is 600 lbF (2,700 Newtons). Bend Radius: ≥20x cable diameter to prevent microbending loss. Core Installation Requirement Urban Areas: 25–40m spacing (concrete poles. It is permissible for fiber optic cable to be wrapped or coiled as long as the minimum bend radius constraints are not violated. Critical design factors include pulling strength limits, bend radius guidelines, water protection, and fire rating compliance, among others. They operate in -60°C to +85°C temperatures.
