A few days ago, it was learned from major telecommunications companies such as China Telecom and China Unicom that in order to help the network "speed up and reduce fees" and cooperate with the "Internet +" era, telecommunications companies are working hard to promote the "reduction of copper into the country" and accelerate the realization of national fiber broadband. Full coverage.
According to communication experts, most of the world’s broadband access networks are based on optical fiber technologies, while China’s broadband access networks are still mainly implemented through copper DSL technology. Copper network and optical fiber access network are two generations of technology that are "cost-effective".
It is understood that each pair of copper wire access bandwidth up to 512Kbps, part of the copper, optical broadband can be up to 20Mbps, but the cost of dual-network parallel maintenance is very high. All-optical network technology can achieve a bandwidth of 50 Mbps, and can reach 100 Mbps or even higher bandwidth without additional costs. It can be seen that achieving full coverage of fiber-optic broadband in the country will be the fundamental way for the network to increase speed and reduce fees.
The reporter learned from China Unicom that in early June of this year, Heze City, Shandong Province, built an all-optical network, changed the old copper cable access to optical fiber, covered the city’s more than 300,000 Unicom broadband users, the city’s urban areas, and 5,755 administrative villages. cover". Since the construction of the all-optical network city in Heze, China Unicom has collected more than 1 million core-to-kilometers of cable and sent more than 400 machine rooms. It is estimated that the average annual electricity savings will be over 7.8 million yuan.
In Dinglou Village, Daji Township, Heze, after optical fiber transformation, China Unicom's 100M high-speed broadband service made Ding Peiyu, an e-commerce company, step away from Zhifu’s dream. He installed 8 broadband products in the company and expected sales to exceed 1400 in 2015. Ten thousand yuan. “In the past, the speed of rural networks was slow, and our efficiency as an e-commerce business was low. Today, the income is the same as the internet speed, and it has doubled!†he said.
The reporter learned that as of now, China Telecom has covered 22 million households in Sichuan Guangwang, covering more than 95% of the city's optical network, and has built a total of 120 Plencotta County, more than 3,000 Quanguang Townships and 21,000 administrative villages. The average broadband bandwidth of optical network broadband users in the province has reached 30M, and the province's per-megabit bandwidth tariff has dropped by 60%.
China Telecom recently proposed that it will speed up the process of speeding up cable broadband and plans to achieve full optical network coverage in 2017. In terms of core infrastructure, China Telecom will accelerate the construction of all-optical network in an all-round way: In 2015, 80% of the optical fiber transformation of the copper community will be completed; in 2017, the optical fiber transformation will be basically achieved, and the proportion of optical broadband users will be 80%.
China Telecom's data shows that as of March this year, China's fiber-optic networks covered households 6.8 times three years ago.
Wen Ku, Director of the Department of Communications Development of the Ministry of Industry and Information Technology, stated that the Ministry of Industry and Information Technology will continue to supervise the improvement of light and strive to fully complete the transformation of the optical fiber in the old district by the end of 2017.
