Bending radius of optical cable laying in ducts
The normal recommendation for fiber optic cable is the minimum bend radius under tension during pulling is 20 times the diameter of the cable (d). Damage may not always be obvious, like a kink in the cable, but may include broken fibers, fibers with higher loss due to stress and cable structural damage that may lead to reliability problems. Proper bend radius control ensures the integrity of optical performance and protects the glass. The correct bend radius calculation is a fundamental prerequisite for high-quality fiber optic installations and is decisive for long-term network performance and reliability. What.
