Speed up the layout of the broadband network of China Telecom into a network of main mode of city lights

Shanghai Telecom, Wuhan Telecom, Guangzhou Telecom have opened their own "optical network" plan, home bandwidth from 2Mbit / s up to 10Mbit / s, 20Mbit / s, and even the future of the 100Mbit / s. China Telecom in the broadband building layout of widespread concern.

Optical Network for Smart City Urban bearer network

In 2009, Shanghai Telecom first open the "city of optical networks," the building, has been attached great importance to China Telecom Group, currently in terms of network construction and business development ahead of other provinces; Wuhan also launched its own "Light City" program, present its fiber to the home has covered the entire city, and Wuhan Telecom pioneered the 20Mbit / s home broadband services; May 2010, Guangzhou has launched a city planning optical networks, accelerate FTTH construction. "City Light Network" has spawned a new era of China Telecom broadband mainstream model building.

Zhang Minfeng Jiangsu Posts and Telecommunications, vice president of planning and design, said the city is a pan-optical network based in the network, is being nurtured things / Pan intelligent city in the network and later the basis for carrying network. City bearer network optical network capacity as a basis has also been senior adviser to the flames of Mao Qian Technology Group recognized. He believes that "the city-optical network" is a strategy for the development of broadband, through development, "Urban optical network" is not only the development of a fiber access network, is more important is to improve the overall level of broadband to improve information technology throughout the city level. On this basis, the realization of triple play, and even the wisdom of the city and other things will play a catalytic role in achieving the operator's support of the local government. In addition, telecom operators are also looking for new business transformation and the need for revenue growth, with the optical broadband access and its various applications, can provide more new broadband services, improve customer satisfaction and ARPU value, is a kinds of win-win strategy.

City brought a high-speed optical network Internet experience, but how can we allow users to pay for it is still a bottleneck in the development of this model. To Wuhan Telecom, its in the first half of 2010 after covering the whole city, the real access to the user at home in the proportion of only 20%, shows that most users have not yet formed a large bandwidth user needs. This is for the operators, the need to develop the user's spending habits, and reduce tariff levels. Zhang Minfeng suggested that for different user needs, develop marketable business applications, and accelerate the promotion of triple play services, such as high definition IPTV and so on.

Scale deployment of FTTH lack of driving force

At present the launch of "optical network" strategy to speed up the city have started the deployment of FTTH, fit a variety of large bandwidth data transfer requirements of the business is still non-FTTH access methods must go. Zhang Jun, deputy chief engineer of Shanghai Telecom, said the total number of broadband subscribers of Shanghai Telecom nearly 400 million, of which occupies one million FTTH users. This proportion is also established in the city of Shanghai Telecom's optical network leadership development process.

FTTB / FTTC is fiber to the home of the transitional mode, FTTH is the ultimate way to fiber access. Wei Leping, China Telecom, Director of Science and Technology Committee, said in recent years, continue to lower the cost of FTTH, is now down to under the carrier's expectations, already has a scale of deployment conditions. Contrast, the current operators in the current network situation and investment among the various development needs of operators, some experts for the scale of deployment of FTTH is also questioned.

Zhang Minfeng said that business needs from the market is, FTTH deployment depends on the business development needs, from the current family information and business applications of information technology industry point of view, IPTV and other policies particularly in the context of uncertainty, large-scale deployment of FTTH need not; it from the network evolution, FTTH is the ultimate mode of fixed broadband access, but the scale of deployment of FTTH fiber network after the core capacity of the original will have a greater impact, especially in the access layer cable , the original cable operators must transform and the corresponding network in order to meet the new size of the deployment of FTTH; from investment returns for operators to protect existing investments to ensure the deployment of broadband in the process of capital investment efficiency, and conform to the majority of consumer demand for broadband home users, not very inclined to "one size fits all" approach to deployment of FTTH.
