Optical Fiber Cable Repeated Bending Testing Machine is used to determine the ability of a fiber optic cable to withstand repeated bending (cyclic flexing). Optical Fiber Cable Impact Testing Machine TT-OFCRB Series allows a cable sample to be bent backwards and forwards at an angle of 180° by bending extreme ends of cables at 90° in opposite directions, while the sample is subjected to a tensile load. The bending arm is designed to hold the cable securely during the entire test, without crushing the optical fibers or inducing optical loss. The bending radius is controlled by replaceable cushioning reels, chosen to match the cable bending radius. The machine is capable of cycling at a rate of 30 cycles per minute.
