Optical Fiber Cable Impact Testing Machine GCJ Series │ GCJ-1000 - Overview Sample The sample is a representative cable length sufficient to carry out the specified test. Apparatus The apparatus allows a hammer with a 25mm rounded edge to drop vertically on a cable sample fixed on a flat steel plate. The apparatus may allow a single or multiple repeated impacts to be imparted on the cable sample. The energy of the impact is determined by the drop height and by the weight of the hammer. Procedure Two procedures are commonly used: 1. A repeated impact test whereby the hammer drops on the same location in the cable sample 25times. 2. The hammer is allowed to drop on 3 different locations in the cable, typically separated by 50cm from each other. The number of impacts in each location is limited. Pass/Fail criteria 1. The fiber attenuation does not increase by more than a predetermined value, typically 0.05dB. 2. In some case, the cable passes the test if there are no fiber breaks. This requirement is usually applied when very high impact energy is used. 3. There are no breaks or cracks in the cable elements. Signs of the impact are considered normal. Introduction HUALONG GCJ-1000 Series Optical Fiber Cable Impact Testing Machine is intended to determine the ability of optical fiber cable withstand impact.

Mechanical part Frame Structure Servo Motor Structure Diagram Compete Machine Diagram Replacement of striking face The national standard impact and military standard impact have different requirements on striking face. So the striking face shall be replaced according to different impact standards. Adjustment of Impact Height As is shown in the following figure, Point A and Point B are rotating points of steel wire rope when the impact height is 300mm and 1,000mm respectively. The rotating part can be installed in either A or B according to the impact height. The installation method is as shown...

Software part Operation panel Operation Instruction Electrifying Turn the power supply switch to the right to “ON”, and then the system is electrified. The counting window displays “0”. The pre-set height and pre-set velocity windows show the input values of last test, The “Test” key is light. Parameter Setting Press the window corresponding to each parameter, the system gives input window. After inputting test parameters, press enter to exit. The different impact height corresponds to different velocity, as is shown in the following: Setting range of testing times for national standard: 10 20...
