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 transmission of information in people's daily work and life.

Faster network speed and greater data throughput are not only the goal of communication engineering construction, but also meet the needs of people's information transmission.  According to statistics, in recent years, major operators have launched three-gigabit and full-gigabit solutions, allowing Gigabit 5G, Gigabit broadband, and Gigabit Wi-Fi to enter thousands of households, making it possible to connect the world without leaving home. bridge.

Today, however, we're going to talk about 10 Gigabit networks.  How fast is the network speed of the 10G network? At present, the network infrastructure of the cloud data center has reached the 400Gbps standard, which is 400 times the bandwidth of 5G, which refers to the Ethernet (Ethernet) whose transmission rate can reach 10Gbps. Converted to bytes, the transfer speed is about 1250 MB/s, and this speed will continue to increase with the advancement of technology.

Advantages of full duplex mode

10 Gigabit networks use full-duplex mode.  In the field of communications, duplex means that two parties in a communication can exchange data with each other.  In the early Ethernet standards, for compatibility, the two working modes of half-duplex and full- duplex are reserved, and the agreement of the working mode is automatically performed by the network device.  The 10G network replaces the original 8b/10b encoding with a more efficient 64b/66b encoding method, which reduces the overhead of checking.

Does 10 Gigabit Network Demand Really Exist?

The answer is yes.  The iteration of communication technology is often accompanied by the rise and fall of old and new giants.  The collapse of Nokia's business empire in the 3G era is the best proof of this.  Therefore, it has become the consensus of major manufacturers to seize the tuyere of technological innovation and not let themselves be left behind.  For individuals and families, 10 Gigabit networks mean faster network speeds, more information carrying capacity, and longer transmission distances.

The high speed of the 10 Gigabit network makes it have a broad application space in teaching. At present, VR teaching has moved from concept to reality, which puts forward higher requirements for bandwidth. The bandwidth required for wireless VR is 2-3 times that of the traditional bandwidth. For high-definition interactive VR, each user needs a bandwidth of 100 Mbps, and the network latency must be less than 15ms to allow users to be immersed in the scene. Cloud VR/AR is the representative. Rich media applications are more demanding on network bandwidth and latency.

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

5G stimulates the development of the Internet of Things, which in turn drives the development of big data.  Today, with the rapid growth of the Internet, the amount of information we have to process every day is increasing, and higher requirements are also placed on the speed of data transmission.  The ever-expanding demand not only promotes the development of network technology, but also expands the application scope of the technology.  The faster information transfer rate will enable the further development of industries and technologies that require high latency, such as unmanned driving, the Internet of Everything, and the Metaverse.  From this perspective, the 10 Gigabit network is the key to achieving other technological breakthroughs.

Achieving the popularization of 10 Gigabit networks 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 end, provide 10 Gigabit access capability, support the traffic growth brought about by enterprises moving to the cloud in the process of digital transformation, and ensure efficient and nearby access for enterprises.  In addition, Shenzhen will also select a number of residential quarters, office buildings, and industrial parks, relying on the gigabit optical network to create a number of demonstration application model projects of all-optical access and whole-house intelligence, to achieve “gigabit-to-home, 10-gigabit input” Enterprise”. It can be seen that the development prospects of the 10G network are improving.  In the future, the 10G network will be promoted first from enterprise users, and eventually into thousands of households.
