In the “10G Optical Network China Tour” Shanghai station research symposium, Ao Li, Chief Engineer of China Academy of Information and Communications Technology, pointed out that “China has realized the ‘county through the Gigabit’, the number of 10G PON ports accounted for more than 85% of the world The number of gigabit broadband users in the world accounted for nearly 70%, the average household access bandwidth reached 499.1Mbps/household, the country has more than 20 provinces and municipalities to carry out the pilot work of the application of 10G optical network technology, China has entered the popularization of the gigabit optical network and 10G optical network sail an important period.”
10Gb optical network sailing first from Shanghai. Dai Bin, a member of the party group and deputy director of the Shanghai Communications Authority, pointed out that since 2024, significant achievements have been made, with the number of 50G PON ports, the percentage of 10G PON ports, and the number of OTN sites owned by 10,000 people leading the country in terms of key indicators, frequent demonstrations in the field of smart homes, intelligent manufacturing, etc., the convergence of new tracks of applications gradually formed, and innovative research continues to emerge, and as a response, Shanghai Telecom has announced that it has built the The world's first 10 Gigabit cloud broadband district (Poly Tianhui District, Yangpu District), and plans to build 26 10 Gigabit demonstration districts in the city by the end of the year. Shanghai Mobile has already identified the pilot district of 10 Gigabit optical network, is developing the corresponding pilot construction program, is expected before the end of the year can be officially for the pilot district public release.
Compared with the gigabit optical network behind the support technology is 10G PON, this 10G optical network behind the promotion of a new generation of 50G PON technology. I can't help but say that China's broadband optical network construction has led the world in these years.
Recently I stayed in Southeast Asia for nearly a month, a very big feeling is that WiFi service is not popular, not cheap. For people who are familiar with the ubiquitous free WiFi in China, it feels more or less uncomfortable. So from this point of view we say that there is still a lot of market demand for optical network price construction in Southeast Asian countries.
If the optical network construction in Southeast Asian countries still has a lot of room for supplementation, China's optical network construction has the problem of finding a way out for the excess bandwidth. lightreading editor Robert Clark commented: “China's gigabit optical network now has a high penetration rate, but there are not enough users, and the development of China's broadband is still facing the battle of the uphill climb. ” He added in his article that with less than a quarter of gigabit broadband being shopped for, operators are having a hard time explaining clearly to users why they need higher bandwidth.
In the Science and Technology Daily's report, 10 Gigabit home innovation services such as home XR, Ultra HD video, cloud NAS, cloud gaming, 3D live streaming, 3D light perception, etc. are expected.The guaranteed bandwidth required for 4K 2D picture quality needed for A1 Digital Human Interaction is nearly 100 Mbps, and the binocular camera used for Ultra HD 3D live streaming can real-time backtransmit 8K Ultra HD video to the live streaming platform, with a maximum bit rate of 150Mbps/road, guaranteed bandwidth 300Mbps/road.
Ideal to ideal, the reality is that these needs are still far from us. Or even if you want, local operators may not be able to provide. China's optical network construction some times is not market-led, we are more technology-led. But in the end, the size of the market to determine the scale of the industry behind the 50G PON called for so many years, behind the whole industry chain are waiting for the market outbreak. A month ago, Shanghai Telecom 50G PON bidding, only purchased 19 sets of equipment.
Broadband development is the country's basic network facilities. This time I was in Southeast Asia, more deeply realize this point. I am very lucky to live and work in a country like China, which can mention the development of optical network to such a high status. I expect that the country can push the construction of China's 10 Gigabit optical network to a new height like building high-speed railways, so that China's optical communication industry can be able to do without having to rely on the market of any other country in the world.
