The MM-GNZ-1000 Series Optical Fiber Cable Torsion Testing Machine is designed to assess the mechanical durability of fiber optic cables when subjected to twisting forces. This machine ensures the cable’s ability to maintain performance under mechanical stress, making it essential for quality assurance in the fiber optic industry. Equipped with precise torsion angle settings, ranging from ±90° to ±360°, and a testing length of 1000mm, it is ideal for evaluating cable performance under a wide variety of torsion conditions. The machine’s automated recording and control functions provide efficient and accurate testing, while its specially designed clamps prevent crushing and allow easy connection for optical measurements during testing.
