How to test the degree of bending of optical cable
IEC 60794-1-111: 2023 defines the test procedure to determine the ability of an optical fibre cable to withstand bending around a test mandrel. Exceed it once and you might get away with it. Exceed it repeatedly, around truss corners, over stage decks, wound tight on undersized reels, and you're stacking up loss that. How do manufacturers prevent these problems and ensure reliable performance? The kink test provides the answer. It simulates extreme bending to identify weak points before cables are used. The performance assessment of FTTH drop cables includes several critical test items:. Fiber optic cable bend radius is a critical mechanical parameter that determines how sharply a cable can be bent without risking microbending, macrobending, signal loss, or long-term structural fatigue. The machine secures the cable at the tensile load point and bends it 90° to both the left and right sides of the plumb line. This test does not assess attenuation detection.
