We spend most of our lives listening to TV commercials about 5G and all the wonderful things it can do for you, and of course we know that 5G relates to wireless communications. For those of us that are in the muck of 3GPP standards, we tend to lose sight of other technologies that are fundamental to the success of wireless communications. Enter F5G or Fifth Generation Fixed Networks. Given all the hype about ChatGPT and given the lack of understanding that I have about optical networking, I decided to ask Bing Chat to write a short intro to an article about F5G, and this is what it came up with: “F5G is the latest advancement in fixed network telecommunication technology. It serves for the optical bandwidth access of fixed networks through wiring and is different from 5G, which is the fifth generation of mobile telecommunication that mainly serves for the access of mobile terminal devices like mobile phones. F5G will open new opportunities by comprehensively applying fiber technology to various scenarios and expanding the reach of fiber to everything, everywhere. This will benefit all industry verticals such as telecom, education, healthcare, finance, energy, transportation and manufacturing. In this article, we will explore what F5G is and how it can improve our daily lives.” Interesting, it even told us what we can expect from the article. So, this month Marcus Brunner was kind enough to give us a bird’s eye overview of Optical Access and in particular F5G Advanced. Enjoy it.
