Optical Fiber Cable Repeated Bending Testing Machine GWQ Series │ GWQ-1000 Overview Sample The sample is a representative cable length sufficient to carry out the specified test. Apparatus The apparatus allows a cable sample to be bent backwards and forwards through at an angle of 180°, the two extreme positions making an angle of 90°on both sides of vertical, while the sample is subjected to a tensile load. The bending arm is designed to permit holding 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 apparatus is capable of cycling at a rate of 30 cycles per minute. Procedure A cable sample is secured to the bending arm while it is in an upright position. A predetermined weight is attached to the bottom of the cable sample. The motor is turned on and the arm oscillates between the two extreme positions flexing the cable. The number of flexing cycles depends on the cable design. Pass/Fail criteria The fiber attenuation does not increase by more than a predetermined value, typically 0.05dB. Introduction HUALONG GWQ-1000 Series Optical Fiber Cable Repeated Bending Testing Machine is intended to establish the ability of a fiber optic cable to withstand repeated bending. Power supply installation While delivering from the factory, the power cord has been connected to the three-phase power plug with capability of 16A. If the re-installation is required, the user shall distinct the live wire and zero line. In order to avoid accidents, it is suggested that the user shall connect the ground wire for the equipment

Test sample (optical cable) installation See the outline drawing of the optical cable back-and-forth bending testing machine for the test sample (optical cable) installation. Firstly, hold the bending arm in the position shown in figure and shut down the machine for the safety. Then replace the bending wheel according to the requirement of the radius of the bending spindle (select one fromΦ100, Φ200 and Φ300 bending wheels and fit them over the small shafts forming right angle chute on the front panel respectively. The distance between two bending wheels shall be enough to pass optical cable...
