Introduction
Optical Fiber Cable Torsion Tester is used to determine the ability of optical fiber cable to withstand mechanical twisting. This machine is specially designed in accordance with IEC-60794-1-2-E7.The length of the specimen under torsion should be sufficient to permit the appropriate clamping and twisting, and long enough to sustain the applied torsion. A typical value for small cables 1m, whereas larger cable samples are usually defined in terms of the cable diameter. A common length is 125 times the cable diameter. Armored cables may require a longer cable sample or a smaller number of torsion cycles.
Apparatus
The actual sample length is longer than the part under torsion to allow connecting the fibers to be tested. The twisting apparatus consists of two cable gripping devices or clamps, one fixed and one that can rotate. The distance between the clamps is connected to suitable turning equipment. The clamps are designed to prevent crushing force on cable and to allow the cable end to exit from both sides to allow optical measurements.
