IT House July 11th According to China Unicom's official news, on July 10th, China Unicom China Telecom Posts and Telecommunications Consulting and Design Institute Co., Ltd. expert He Yongtao said at the 2019 China Internet Conference that China's optical cable is about 300,000 faults per year. Among them, 7,000 trunk lines, mostly due to external force construction.
He Yongtao said that after hard work, China's communications industry can now control the fault of the trunk cable to about three thousand times a year. The repair time limit is three hours, and the plateau snow mountain is four hours. This is a very high level in the world. . To this end, we need to pay a maintenance cost of 200 yuan to 3,000 yuan per kilometer.
More than 99% of the information created by humans is delivered on the basis of fiber-optic infrastructure. He Yongtao introduced that the experience data from 2011 to 2018 shows that February is the low point of the incidence of fiber infrastructure failure, which is the impact of less construction during the Spring Festival holiday, and the lower failure rate in November, December and January. It is also due to the large-scale reduction of field infrastructure construction in the cold northern regions in winter; the peak period is in July, when most of China's regions are in flood season, and natural disasters are more harmful to fiber infrastructure.
In addition, there is another very interesting phenomenon, and a failure rate is also low in June every year. This is because June is the test season, the junior high school entrance exam, the senior high school entrance examination and the college entrance examination. The parents have blocked all the excavators near the examination room.
