| Minimum bend radius and maximum pulling tension Requirements

- The bend radius for intrabuilding 2 and 4-fiber horizontal optical fiber cable shall not be less than 25 mm (1 in) under no-load conditions.
- When under a maximum tensile load of 222 N (50 lbf), the bend radius shall not be less than 50 mm (2 in).
- The bend radius for intrabuilding optical fiber backbone cable shall not be less than that recommended by the manufacturer.
- If no recommendation is known, then the applied bend radius shall not be less than 10 times the cable outside diameter under no-load conditions and not less than 15 times the cable outside diameter when the cable is under tensile load.
- The bend radius for interbuilding optical fiber backbone cable shall not be less than that recommended by the manufacturer.
- If no recommendation is provided or known, then the bend radius shall not be less than 10 times the cable outside diameter under no-load conditions and not less than 20 times the cable outside diameter when the cable is under a tensile load up to the rating of the cable, usually 2670 N (600 lbf).
