Application
GNZ-1000 Series Optical Fiber Cable Torsion Testing Machine is intended to establish the ability of a fiber optic cable to withstand mechanical twisting.
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.
