摘要
光纤衰减分布存在一定变化量,在光缆生产过程中,由于附加衰减的影响,光纤衰减偏大的区域可能会造成光缆成品衰减超标。为了降低此类质量风险的发生,在OTDR衰减测试中,引入"衰减不均匀性"检查项目,通过观测整段光纤的衰减分布,找到可能造成衰减值超标的异常区域并提前进行处理。因此,如何提高检测人员对于光纤衰减不均匀性的分辨能力,对降低光缆衰减超标质量问题,有着重要意义。
Optical fiber attenuation distribution exists a certain amount of change,in the Cable production process,due to the impact of additional attenuation,optical fiber attenuation large area may cause Cable production attenuation exceeds the standard.In order to reduce the occurrence of such quality risks,the"attenuation non-uniformity"inspection item was introduced in the OTDR attenuation test.By observing the attenuation distribution of the whole section of the optical fiber,the abnormal areas that may cause excessive attenuation values were found and dealt with in advance.Therefore,how to improve the tester personnel with optical fiber attenuation non-uniformity resolution,is very important to reduce the quality risk.
