Bending radius of indoor optical cables
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. Note:. 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. While installers are aware of the fundamental importance of minimum bend radii, they often lack the practical know-how to. The fiber optic bend radius refers to the smallest radius a fiber cable can be bent without causing unacceptable signal degradation or physical damage. It is measured from the inside of the bend, not the outer curve.
