At the forthcoming "Optical Access Technology Forum", Mao Qian, honorary director of the Optical Communication Committee of the China Institute of Communications and chairman of the China FT Forum, said that professional networks have a long way to go, and the development of 10 Gigabit broadband is about to emerge.

Gigabit broadband, a long way to go

At present, my country has built the world's largest fixed broadband network, and all cities above the prefecture level across the country have achieved full coverage of optical fiber networks.

Data shows that the total number of fixed Internet broadband access users reached 514 million, a year-on-year increase of 9.9%. The country's rural broadband users increased by 10.75 million from the end of last year, bringing the total to 153 million, a year-on-year increase of 8.4%. The total number of fixed Internet broadband users with access rates of 100Mbps and above reached 472 million, accounting for 97.4% of the total number of fixed broadband users. The number of users with access rates of 1000Mbps and above is 16.04 million, accounting for 3.3% of the total number of fixed broadband users.

 

Broadband acceleration is a significant feature of the rapid development of the modern information society. At present, gigabit broadband networks have entered large-scale commercial use, and basic telecommunications companies are accelerating the deployment of gigabit networks based on 10G PON technology.

 

According to OVUM statistics, 234 operators in 57 countries around the world have released gigabit broadband construction plans, committed to building a solid foundation for the digital transformation of the economy and society.

"Gigabit optical bandwidth includes multiple aspects of home broadband, industry, and urban applications." Mao Qian pointed out that high-end and large-scale online games require high-bandwidth and low-latency access to ensure that the gigabit optical bandwidth can be increased. Streaming social media has extremely high requirements for user interaction. High-definition, high-fidelity audio and video interaction requires the network to have the support of large bandwidth, low latency and high stability. Gigabit network is an inevitable choice for the ultimate social experience of streaming media. . Online education, home office, online meeting, telemedicine, smart home, safe city, smart manufacturing, etc. all require a gigabit broadband platform to have a good user experience.

On March 24 this year, the Ministry of Industry and Information Technology issued a notice on the "Dual Gigabit Network Coordinated Development Action Plan (2021-2023)". Someone in the industry has proposed that 5G will replace home broadband. Mao Qian did not agree with this view. He said, “In fact, the two are not a substitute. The high-speed, flexible, mobile and home-wide stable, reliable and large bandwidth of 5G are used in different scenarios. They can (and should) complement each other, develop coordinated development, and keep pace with each other. This is also the general trend. ."

"Fixed-mobile synergy, complementary advantages." Mao Qian pointed out that the Gigabit optical network has the advantages of large transmission bandwidth, strong anti-interference, and microsecond-level connections in indoor and complex environments, and the high flexibility of 5G networks, enhanced mobile, and The advantages of big connection, in the long run, the high-quality development of home broadband and the cooperation of 5G will be the information foundation that supports the innovation and prosperity of various industries. At the same time, PON technology can support the rapid deployment of 5G. "

"Fixed broadband access networks are supported by 10G PON access technology, which can bring gigabit broadband access capabilities. However, when the Gigabit network coverage and applications are further upgraded, they are still somewhat powerless." Mao Qian believes that gigabit broadband Although it has been achieved, there is still a long way to go for future development.

 

10 Gigabit broadband, ready to come

As people's living standards continue to improve and become more intelligent, online office/meeting/work interaction, etc., put forward more and higher requirements on the network environment, and 10 Gigabit broadband is about to emerge. Mao Qian predicts that the initial 10 Gigabit broadband will be mainly deployed in campus/enterprise/Internet cafes/key customer scenarios, and then it will develop into home broadband.

In foreign countries, Google proposed a plan to deploy 10 Gigabit broadband in 2014; South Korea also proposed to promote 10 Gigabit broadband services in 2018; Japan’s NTT East/West launched 10 Gigabit fiber access services in early 2020 with download speeds. It can reach 1.25GB per second, and the services provided are symmetrical, with both the upstream and downstream bandwidth rates being 10Gbps, and the monthly fee is about 380 yuan.

Domestically, many explorations and attempts have been made in 10 Gigabit broadband. In 2012, Jishi Media was a complete solution for the overall solution of 10 Gigabit fiber-to-the-home I-PON technology. In 2019, China Telecom proposed to accelerate the progress of 10 Gigabit optical networks into commercial buildings and industrial parks on the basis of the full coverage of Shanghai's gigabit broadband network. At the same time, various technologies supporting 10 Gigabit broadband are gradually maturing, and 10 Gigabit broadband is visible.
