Research On Optical Fiber Loss Detection Technology Based On Optical Communication Infrastructure

Since the beginning of the 21 st century,global and China's fiber demand has continued to grow.Since 2006,the global fiber market has maintained a compound growth of 15%.China maintains a compound growth rate of about 25%.Overall,fiber optic cable demand continues to be strong.China's demand will dominate global markets over the next few years.In 2018,it is expected that China's optical fiber usage will reach 350 million core kilometers,an increase of 12.5 percent year on year,and the proportion of demand will increase from 20 percent in 2006 to 58 percent.China's fiber-optic backbone network,metropolitan area network,the markets in areas such as popularization and 4G/5G construction,as well as the policy provide a good external development environment under the drive of leading the development of optical fiber markets around the world in the past decade.According to statistics,the demand growth rate of China's fiber market has been kept at more than 25 percent since 2006,far exceeding the global growth rate of 15 percent,and China consumes nearly 60 percent of the fiber demand of 20 percent of the population.Now due to response the government "broadband China","Internet + strategy",and actively participate in the formulation of standards 5 g major policy background,the three major telecom operators will also continue to input to the optical network time longer.In the short term,the three operators will continue to increase the construction of fixed-line broadband,and will increase the construction of 5G,Internet of things,industrial Internet and data center in the medium to long term.Globally,fiber coverage is only about 30%.As the foundation of network construction,optical fiber will have a huge market space in the future.Huge demand has brought significant market opportunity,fiber optic product quality is good or bad fault and late for the influence of the network quality is huge,its influence relates directly to the user's experience.In China,the demand for finished fiber products is mainly concentrated in the collection cycle of the three major operators,so it is particularly important for operators to control the quality of finished products.The detection of fiber optic cable includes four major links.The first link is the material detection of the fiber optic cable manufacturer for the downstream material supplier.The second link is the testing of the fiber optic cables by the optical fiber manufacturers.The third link is the delivery stage,and the operators will re-examine the finished products.The fourth link is the time when the cable products are put into use,and the operators' generation company fails to check the lines periodically to ensure the smooth operation of the line.Based on the author's actual work experience,this paper elaborates the detection process of these four links.It is proved that the quality of fiber optic cable has an important influence on user experience.In this paper,the research on the detection experiment and the fiber production technology has important guiding significance for the construction of communication infrastructure.
