This equipment is suitable for testing the ability of optical cable to withstand mechanical torsion. By applying positive and negative torsion force, the optical fiber is not broken for qualified optical cable, the attenuation change of optical fiber is not more than the value specified in the detailed specification of optical cable products, the optical cable sheath is not cracked, and the cable core component is not damaged.
Max torsion length
±90°, ±180°, ±360°for choice
(5～30) times/min (when the torsion angle is at ±180°), set arbitrarily
