Bend Radius | Alker Fibre Optic Specialists

Bend Radius

The radius of curvature that an optical fiber can bend without sustaining damage. The smaller the bend radius, the greater the material flexibility (as the radius of curvature decreases, the curvature increases). A minimum bend radius is the radius below which an optical fiber or fiber optic cable should not be bent. The manufacturer should specify the minimum radius to which the cable may safely be bent during installation, and for the long term, the former is somewhat shorter than the latter. The minimum bend radius is in general also a function of tensile stresses during installation, while being bent around a sheave while the fiber or cable is under tension.
POF is a very flexible medium and is not readily suscpetible to damage from bending.
