"ftth" China Road: Inhibition Of Development Cost!
Just a few seconds to download a movie on Beijing, Wuhan, Guangzhou, Shanghai and other users, is not whimsical.
"But we FTTH residential broadband (FTTH), and much faster than ADSL." Mid-March, Beijing Hui Long Guan Cheng Lung Yeuk Yuan more households (a pseudonym) said, proudly showing off to reporters.
Wuhan Yangtze apartment for Wang Zhiqiang (a pseudonym), this has already worth mentioning?? Three years ago, long fly apartment 158 FTTH users has become a pilot project in China. Johnny also was able to enjoy through the households of high-bandwidth fiber-optic network network swim, such as viewing figures TV , 3D gaming, video telephony, video-on-demand.
Every indication to replace the ADSL for the final mission of the "FTTH" is facing an unprecedented opportunity. But the problem is, FTTH really as good as you imagined?
FTTH to replace the ADSL "FTTH is a three-high network: high-bandwidth, high-speed, high quality, is currently the world's most advanced means of user access." In an interview with reporters, Stallone Communicate Chairman Zhang Xianqing said. After the dial
in, ISDN narrow, ADSL broadband, after a few times in the face of an increasingly rich Internet applications, network bandwidth required to achieve a qualitative leap. Therefore, the concept of FTTH has been proposed 10 years ago, but high prices and other factors, Expert Are many with "last mile" to outline its distance from real life.
According to report, in the FTTH network, means that families can have a 100Mbps or 1000Mbps bandwidth, that is, the user downloads a theoretical limit of the fastest high-definition movie takes only a few seconds.
Contrast with FTTH, ADSL is increasingly showing its limitations. Leading broadband expert, Fiberhome Technology Group chief engineer Mao Qian said that the current universal ADSL Standard Downlink channel rate of 8Mbps, upstream channel is 512Kbps. In the past, such as asymmetric data rate is suitable for traditional business, but with P2P, and interactive video, high definition movies to its rapid growth, ADSL become increasingly unsuited to the needs of users.
The "Father of China's optical fiber," Zhao Zi-Sen Fellow of view, this stage is called "broadband" in ADSL, LAN, cable TV cable access eventually, but short-lived, perhaps only FTTH is the best choice.
Wu Hequan Chinese Engineering Academy said, FTTH can replace currently used by the Ethernet, ADSL and cable Internet access 3 main ways. "It enables users to access speeds of up to 1,000 times the present can be called true broadband."
Fact, because fiber-optic electromagnetic interference from electromagnetic leakage problem does not exist, fiber addition to high-speed mass data can be advantages, its long-distance transmission, the stability and the confidentiality of such information has a copper cable irreplaceable role.
All the good, the July 2004, Johnny is located in Wuhan Yangtze apartment became the first pilot FTTH in China. Year in November, Wuhan, Hubei, China Netcom and Telecom announced the successful pilot, spent 10 million yuan each, input fiber to the home of commercial operation.
Seems to be ripe, Netcom and Telecom started the field of large-scale Sharu FTTH. After the pilot project in Wuhan, Guangzhou, Beijing, Shanghai and other cities of China Telecom FTTH pilot. To data from China Telecom, Wuhan Telecom FTTH now has more than 20,000 users.
November 12 last year, announced on China Netcom will invest 15 billion yuan implementation of the "Light of Copper" strategy. Netcom Beijing and other places in the pilot program of new FTTH broadband access, and broadband Internet access speeds up to 8Mbps, the end of 2007, Beijing covering the user has more than 20,000.
Every indication, "FTTH" is facing an unprecedented opportunity. The end of 2007, Wuhan municipal government issued a document called, to determine fiber users in 2008 to 10 million, will reach 500,000 by 2010.
