The 19th China International Optoelectronics Expo (CIOE China Optoelectronics Expo) opened grandly at the Shenzhen Convention and Exhibition Center.
As a benchmark forum for the optical communications industry - the "2017 Optical Communications Technology and Development Forum" is also grandly held here. This forum will focus on a comprehensive and in-depth discussion and analysis of the opportunities and challenges faced by the optical communications industry. .
Industry giants such as China Mobile, China Unicom, China Telecom, Wuhan Academy of Posts and Telecommunications, China Academy of Information and Communications Technology, Huawei, Broadcom, EXFO and other industry giants were all present.
At the forum, Ao Li, deputy director of the Institute of Technology and Standards of the China Academy of Information and Communications Technology, delivered an important speech. pound speech.
He pointed out that my country's optical fiber broadband users rank first in the world in terms of the proportion of broadband users. In addition, broadband has entered the era of gigabit access, and 10GPON has gradually become the mainstream technology of PON networks.
In recent years, my country's fixed broadband network capabilities have been greatly improved, and fiber optic access has now become the most important method of broadband access in my country.
As of 2017 By the end of June this year, FTTH coverage reached 1.01 billion households, more than 10 times that of 2012, and all local cities across the country have basically become "optical network cities".
At the same time, my country's fiber optic broadband has already been developed. Gradually surpassing countries such as Japan and South Korea, which have led the broadband development for many years,
According to statistics, my country's fiber-optic broadband users account for 80.9% of broadband users, ranking first in the world; Japan's share reaches 74.1%, ranking first in the world. Ranking second; South Korea ranks third with 72.5%.
Global fiber-optic broadband users account for approximately 50.0% of broadband users, and China's ratio has exceeded the global average by a large margin.
As of the end of June 2017, the number of 4G base stations in my country reached 3.015 million. The scale of 4G network ranks first in the world, covering urban and rural areas. 4G users account for 65.1% of mobile phone users.
Not only that, our country Fixed broadband users have also shown rapid growth.
As of the end of June 2017, the total number of fixed broadband users in my country reached 357.12 million (including basic telecommunications companies and secondary broadband access service providers). According to the Broadband Development Alliance's "China Broadband Popularization Report", the household penetration rate of fixed broadband has reached 16.9%, which is close to the target value of the "13th Five-Year Plan" by the end of 2020 (the benchmark is average growth).
According to the data, the penetration rate of fixed broadband has reached 16.9%. By the end of June 2017, the number of users of China Telecom, China Mobile and China Unicom reached 152.11 million, 93.041 million and 76.801 million respectively. China Telecom accounted for the highest proportion, reaching 42.6%. China Mobile grew rapidly; other operating companies had 35.16 million users. , accounting for about 9.8%
According to the Broadband Development Alliance's "China Broadband Popularization Report", As of the end of June 2017, the cumulative number of mobile broadband (3G and 4G) users in my country reached 1,082.66 million, exceeding the 1 billion mark, and the penetration rate of mobile broadband users reached 78.3%, which is close to the target value of the end of 2019 in the "13th Five-Year Plan" (Based on average growth), the gap with developed countries has narrowed rapidly.
Among them, the number of users of China Telecom, China Mobile and China Unicom reached 181.889 million, 687.849 million and 167.069 million respectively, with China Mobile accounting for the proportion. Up to 63.5%;Mobile reseller users were 45.86 million, accounting for 4.2%.
Ao Li said that broadband has entered the era of gigabit access, and 10GPON has gradually become a PON network Mainstream technology, traditional PON is being upgraded to 10G PON, and broadband will increase by 10 times.
The three major operators are also actively deploying 10G PON.
China Unicom's 10G PON has entered the comprehensive deployment stage. At present, China Unicom has clarified the speed-up plan for the broadband access network: 1GPON FTTH will be the main one, supplemented by 10GPON FTTB, and 1GPON FTTH will be deployed on a small scale in developed areas.
China Mobile 10G PON has carried out equipment testing and pilot projects.
China Telecom’s 10G PON solution has been commercialized on a large scale.
Ao Li said that the current cost of 10G PON ONU is nearly 10 times that of GPON/EPON, mainly due to the high cost of 10G optical modules, which has become a bottleneck for large-scale deployment in the future.
