optical fibers information

According to a recent survey by Nihon Keizai Shimbun on the network speed of high-speed fixed communications such as optical fibers in various countries, the Organization for Economic Cooperation and Development (OECD) Of the 36 Member States, Japan ranked 7th in 2015 and fell to 23 in 2018. The enhanced speed of communication equipment in Japan cannot keep up with the popularity of large-capacity video, and the Internet speed at night is slower than that of major Southeast Asian countries. When 5G is enabled, the amount of data passing through optical fiber will explode. If this situation is ignored, Japan's industrial competitiveness will decline. Japan's night network speed dropped sharply, and Nihon Keizai Shimbun used the communication speed measurement plan of Google and Princeton University in the United States 'M- Lab 'freely released data after 2010, with the help of the University of Tokyo, selected and analyzed 2 of 199 countries and regions by country and time period. 300 million copies of data. The survey results show that Japan's network speed has dropped significantly. Japan's Internet speed (1 day average) It reached a peak of 14 Mb/s in December 2015 when it was excessive to optical fiber. The 2-hour HD movie can be downloaded in 50 minutes. At that time, Japan's Internet speed was comparable to that of Denmark, Holland and other top 5 countries. However, Japan's Internet speed increase has stagnated, 2018-April is only 12. 6 Mb/s. Denmark and Sweden reached about 40 MB/s, while the United States and Britain also surpassed Japan. Japan's Internet speed dropped sharply at night when video viewing increased. The internet speed is only 5 Mb/s at 10: 00 p. m. , which is only one-fourth of that in the morning. Compared with non-OECD member countries, Japan's Internet speed is similar to Russia's average daily internet speed of less than 10 MB/s, and its Internet speed at night is slower than that of Thailand and Malaysia. The average daily network speed of Taiwan and Singapore also exceeds that of Japan. The background is that Japan faces unique problems. In Japan, data is transmitted via line operators and Internet service providers such as NTT East Japan and NTT West Japan (ISP)Equipment for both sides. The investment in the connection device is basically the responsibility of the line operator. The connection device of NTT East Japan and NTT West Japan with nearly 70% fiber share has become a bottleneck. Due to the adoption of fixed charges, enterprises will add connection devices according to the growth of users. But now the growth of user contracts is weak, and the traffic is increasing sharply.  The investment speed cannot keep up with the growth rate of traffic. Yamaguchi Zhaozheng, Minister of Equipment planning department in NTT East Japan, said, 'if the amount of data increases at the current rate, the business affordability may reach the limit '. NTT East Japan and NTT West Japan have not announced the investment in optical fiber equipment. In 2017, the total investment of the two enterprises was 5094 yen, a decrease of 30% compared with 2012. NTT East Japan said, 'The background is to improve the efficiency of investment and only make necessary investments '. Japan Internet Service Provider Association (JAIPA) NTT East Japan and NTT West Japan are required to take the increase of traffic as the basis for investment judgment, but the two companies have not changed their guidelines. On the one hand, Japanese communication operator KDDI enhances equipment based on the growth of traffic. Japan's competitiveness may decline after 2019, 5G, which is 100 times faster than the current wireless communication speed, will enter the practical stage in various countries around the world. However, with the convergence of playback and communication, if the Internet of Things (IoT) And the popularity of self-driving cars, wireless communication will bear a huge burden. There are many situations where optical fibers are used via WiFi at home or at work.  In order to maximize the performance of 5G, it is necessary to expand optical fibers. Sato Zhizheng, a professor of a South University who is familiar with Japan's communication policy, sounded the alarm and said, 'if the communication infrastructure cannot be established efficiently, innovation will not be generated and the country's competitiveness will decline '. Northern Europe is promoting electronic administration, and well-known content companies such as Netflix have been born in the United States. Due to the lack of measurement data, China's network speed ranks behind 150 in the world, but China's coastal areas are continuously expanding its communication network to promote the birth of start-ups and the vigorous development of the network industry. In Japan, in order to promote the investment in high-speed communication networks, the meeting of people of insight in Japan's Ministry of Internal Affairs has begun to discuss how to share the investment, but the specific content has not yet been finalized. If the enhancement of optical fiber stagnates, Japan's industrial competitiveness will further decline in the 5G era.
