Plastic optical fiber to the home represents the future of broadband in a country
Due to the large diameter and numerical aperture of plastic optical fiber, it has a stronger bandwidth capability than copper transmission media. The propagation speed and capacity of 8 copper wires are equivalent to 2 plastic optical fibers. However, the price of copper per ton is as high as 200,000 to 300,000 yuan, and the price is increasing year by year. However, a plastic optical fiber with a diameter of 1 millimeter and a weight of 1 gram and a length of 1 meter is only 0.2 to 0.3 yuan. The three networks in the "three-play" strategy refer to telecommunication networks, radio and television networks, and the Internet. With the advancement of this strategy, plastic optical fiber is used to replace the transmission of the above three signals, and the transmission cost will be greatly reduced.
Fiber-to-the-home represents the future of broadband in a country, and has a great role in promoting optical devices, fiber optic cables and other industries. The Ministry of Information Industry of China has begun to formulate relevant FTTH standards. Experts predict that the domestic FTTH market will be fully launched in 2006. Entering the period of large-scale construction, Beijing, Changsha, and Wuhan have started FTTH pilot projects. For example, Wuhan has built the first domestic fiber-to-the-home pilot platform, and nearly 10 fiber-to-the-home projects have been completed or under construction, with a user scale of approximately 5000 It is estimated that the number of users will reach 50,000 from 2006 to 2007. At present, there are 25 million broadband users in China, and 12 million new users will be added every year by 2007. If about 20% of users adopt FTTH, it will form an FTTH equipment market of about 80 billion yuan, and annual operating business revenue will reach 18 billion. Yuan above. According to statistics and forecasts from the Information Institute of the Institute of Telecommunications Research of the Ministry of Information Industry, the global fiber access market will grow rapidly in the next 5-10 years, and the capital used for fiber to the home will increase from 5 billion US dollars this year to 22.8 billion US dollars. , Of which capital expenditure in the Asia-Pacific region is US$12 billion. China and India will become the fastest-growing countries. It is estimated that China's FTTH investment will account for 1/3 of the Asia-Pacific region.
In addition, some cities in my country have successively proposed the goal of upgrading telecommunications networks and accelerating the pace of fiber to the home. The Beijing Olympics Organizing Committee announced that it will invest 6.6 billion U.S. dollars to expand and upgrade its telecommunications network by 2008. Shanghai also proposes to increase its telecom operating income from more than 10 billion yuan to 43.5 billion yuan before 2010. In addition, my country’s backward facilities The western region will also accelerate the pace of informatization in the process of large-scale development, all of which provide a realistic basis for the FTTH market space.
