• 99% of China `s population achieves 4G network coverage, and over 95% of the administrative villages pass the fiber broadband network

  2022 / 04 / 15

  According to data released by the Ministry of Industry and Information Technology of China, as of the end of April, China's 4G network covers 95% of the administrative villages and 99% of the population in the country, and more than 95% of the administrative villages have achieved optical fiber broadband network access. According to the Ministry of Industry and Information Technology, the implementation of the [Special Action for Promoting Internet Speeding up and Fee Reduction and Speeding Up the Cultivation of New Momentum for Economic Development 2018" in 2018 will enable consumers and the whole society to further enjoy the results brought by the development of information and communication. The data shows that in the construction of broadband networks, as of the end of April, the investment in fixed assets was 67.1 billion yuan, an increase of 16% over the same period last year. 40 million optical fiber broadband ports were newly added nationwide; 120,000 4G base stations were newly built, with a total of 3.4 million. Multi-regional telecommunications companies implemented a new round of free speedups. The number of users using broadband of 100M or more nationwide increased by 37 million, accounting for 47% of broadband users. Dozens of cities including Beijing, Shanghai, Chongqing, Chengdu, and Zhengzhou have already begun to provide Gigabit broadband services. The Broadband Development Alliance recently released the "China Broadband Rate Status Report", saying that in the first quarter of 2018, the average download rate of C

• What is the difference between a fiber optic quick connector pre-embedded fiber and a non-embedded (straight-through) fiber patch cord pigtail?

  2022 / 04 / 15

  At present, with the continuous development of the domestic communication industry, optical fiber communication has entered the practical stage, and the scope of application is becoming wider and wider. At the same time, more and higher requirements are put forward on the optical fiber connector, and its main The development direction is that the appearance is miniaturized, the cost is low, and the performance requirements are getting higher and higher. The following is a detailed explanation of the fiber optic quick connector embedded optical fiber and non-pre-embedded (straight-through), optical fiber jumper, pigtail, between the difference. The difference between embedded fiber optic quick connector and straight-through The fiber optic quick-connect connector uses two technologies: pre-embedded fiber and non-embedded (straight-through) fast connector fiber. The main difference is in the connection point and connection method: (1) Connection point setting The connection point of the embedded fiber is set inside the connector, the pre-embedded fiber has a preset matching liquid, and the non-embedded (straight-through) fiber connection point is on the surface of the connector, and the matching liquid is not preset, and is directly connected to the target fiber through the adapter. (2) Connection method The fiber optic quick-connect connector inserts and fixes the fiber into the pin and polishes the surface of the pin to achieve alignment in the coupling tube. The outer components of the pins are made of metal or non-metal materials. The butt end of the pin must be ground and the other end typically uses a bend limiting member to support the fiber or fiber optic cable to relieve stress. The coupling tube is generally made of two semi-synthetic, fastened cylindrical members made of ceramic, or bronze, and is equipped

• Fiber optic cable industry demand remains high

  2022 / 04 / 15

  The retreat of light into the copper to ensure that the optical fiber cable industry demand remains high China's optical fiber and cable industry has risen with the development of national communications. Optical fiber cables have applications in the communications backbone network, metropolitan area network, and access networks. In recent years, the total mileage laid has steadily increased. The average annual increase of 20% . We believe that with the increasing demand for network bandwidth in China, Guangjin Copper Retreat will become a major trend, which will ensure that the growth momentum of the industry can continue in recent years. At present, China's broadband penetration rate is calculated at 3.4 people per household, which has reached 27% . However, China's broadband transmission speed has always had the problem of [ broadband is not wide " . This is due to the oligopoly in the domestic broadband operation industry, 3G The large investment in capital consumption, the limited IPTV services, and the slower integration of operators have resulted in a slowdown in access network investment and other factors. As a result, the average broadband speed is only 600kbps, 1.7Mbps significantly behind the average level of the world. According to Speedtest's statistics, China's average speed of access to the Internet ranked
