From the first generation to today's fifth generation mobile communication technology, 5G has undoubtedly become the head "net red" in the communication industry, but do you know that 5G network only represents mobile communication, not including fixed network? Fixed networks have also entered their fifth generation, dubbed "F5G". This article will discuss F5G with you.

The concept of F5G originated from the European Telecommunications Standardization Institute (ETSI), which refers to the fifth-generation fixed network, namely fiber broadband, with three key features: all-optical connection, enhanced fixed broadband, and ultimate experience. 5G is flexibly deployed for wireless access scenarios and is suitable for occasions requiring mobility. It mainly serves outdoor or mobile application scenarios such as mobile phones, drones, and Internet of Vehicles, with a focus on wireless; while F5G is stable and reliable for fixed access scenarios. For fixed, large bandwidth, low latency, and high security scenarios such as homes, enterprises, factories, and hospitals, the focus is on wired connections. 5G and F5G jointly build full connection coverage of fixed and mobile scenarios to meet the connection needs of thousands of industries.

In 2019, 5G entered a period of accelerated development, while fixed network technology stagnated due to lack of planning and promotion. In the second half of 2019, 10 companies including China Telecom, Huawei, Telecom Italia, and Portugal Telecom took the lead in the coordinated development of fixed network technology, promoted the standardization of technology, and jointly proposed the establishment of the F5G working group. In January 2021, the "Global Optical Communication Industry White Paper" was released, which pointed out that the optical communication industry has set off a new round of development opportunities under the role of technology-driven intergenerational evolution and market-driven network transformation and upgrading, and promoted the arrival of the era of "Optical Connectivity of Everything". It also gives unlimited potential for the development of fifth-generation fixed-line communication (F5G). At the end of February 2020, ETSI announced the establishment of the Fifth Generation Fixed Network Working Group (ETSI ISG F5G) to define F5G and promote the intergenerational evolution of fixed networks.

Although F5G and 5G are different concepts, and there is no affiliation between the two, they share some technologies and networks, representing the latest technologies of "fixed network" and "mobile network" respectively, and can be applied in scenarios. achieve complementarity. Generally, when the optical fiber is reachable, F5G will be preferred, because F5G can bring more bandwidth, lower latency and more stable, safer and more reliable network characteristics, which lays the foundation for the future application of F5G in the field of intelligent industry. .

With the rapid development of F5G/5G, optical chips, optical modules, optical communication equipment and other fields have attracted more and more capital, and capital has also become a booster for the continued rapid development of the industry. At present, China has built the world's largest information and communication network. By the end of May 2020, the proportion of optical fiber access users reached 93.1%, ranking first in the world.
