Ten times faster than 5G? What is the future of 10G network?

In the digital age, how to use technology to promote production and improve the quality of life has become a profound issue. Communication technology plays an important role in the construction of communication projects and the information transmission in people's daily work and life.

Faster network speed and greater data throughput are not only the goals of communication engineering construction, but also meet people's needs for information transmission. According to statistics, in recent years, major operators have launched three-gigabit and full-gigabit solutions, bringing gigabit 5G, gigabit broadband, and gigabit Wi-Fi into thousands of households, becoming a bridge that can connect to the world without leaving home.

However, what we are going to discuss today is 10G network. How fast is 10G network? At present, the network infrastructure of cloud data centers has reached the 400Gbps standard, which is 400 times the bandwidth of 5G, referring to Ethernet with a transmission rate of 10Gbps. If the data unit is converted into bytes, the transmission speed is about 1250 MB/s, and this speed will continue to increase with the advancement of technology.

Advantages of full-duplex mode

10G network uses full-duplex mode. In the field of communication, duplex means that both parties can exchange data with each other. In the early Ethernet standards, for compatibility, half-duplex and full-duplex working modes were retained, and the network equipment automatically negotiated the working mode. 10G network replaced the original 8b/10b encoding with a more efficient 64b/66b encoding method, which reduced the overhead of verification.

Is there really a demand for 10G network?

The answer is yes. The iteration of communication technology is often accompanied by the rise and fall of new and old giants. The collapse of Nokia's business empire in the 3G era is the best proof of this. Therefore, it has become a consensus among major manufacturers to seize the opportunity of technological innovation and not fall behind. For individuals and families, 10G network means faster network speed, more information carrying capacity, and longer transmission distance.

The high speed of 10G network makes it have a wide application space in teaching. At present, VR teaching has gone from concept to reality, and has put forward higher requirements for bandwidth. Wireless VR requires 2-3 times the bandwidth of traditional ones. HD interactive VR requires 100Mbps bandwidth per user, and the network latency must be less than 15ms to make users feel immersed. Rich media applications represented by Cloud VR/AR are more demanding on network bandwidth and latency.

In addition to teaching, the development of the Metaverse also depends on the improvement of basic network speed. Liu Yunjie, director and chief scientist of Purple Mountain Laboratory, an academician of the Chinese Academy of Engineering, pointed out at the "6G Network Architecture and Key Technology Roundtable Forum" of the 2022 Global 6G Technology Conference that the Metaverse has four major requirements for network performance, including latency. The premise for realizing XR and tactile business collaboration, holographic perception communication and other technologies in the Metaverse is that the end-to-end latency is less than 1ms.

5G stimulates the development of the Internet of Things, which in turn drives the development of big data. As the Internet grows rapidly, the amount of information we have to process every day is increasing, and higher requirements are placed on data transmission speed. The ever-expanding demand is not only driving the development of network technology, but also expanding the scope of technology application. Faster information transmission rates will further develop industries and technologies with high latency requirements, such as driverless cars, the Internet of Everything, and the Metaverse. From this perspective, 10G networks are the key to achieving other technological breakthroughs.

The popularization of 10G network is a long process from commercial to civilian use. Taking Shenzhen as an example, Shenzhen will promote the deployment of large-capacity OTN nodes to the enterprise side, provide 10G access capabilities, support the traffic growth brought by enterprises going to the cloud during digital transformation, and ensure efficient and nearby access for enterprises. In addition, Shenzhen will also select a number of residential communities, office buildings, and industrial parks, relying on gigabit optical networks, to create a number of demonstration application model projects with all-optical access and whole-house intelligence, and realize "gigabit to the home, 10G to the enterprise". It can be seen that the development prospects of 10G network are good. In the future, 10G network will start with enterprise users and eventually enter thousands of households.
