In the previous article (link), Xiao Zaojun introduced the development history of broadband technology from ISDN, xDSL to 10GPON. Today, let’s talk about the upcoming new generation of optical fiber broadband technology-50GPON. █F5G and F5G-A Before introducing 50GPON, let’s talk about F5G and F5G-A. In February 2020, ETSI (European Telecommunications Standards Institute) promoted a fixed communication network technology system based on 10GPON+FTTR, Wi-Fi6, 200G optical transmission/aggregation, OXC and other technologies, and named it F5G. That is, the fifth generation fixed network communication technology (The5thgenerationFixednetworks). F5G is a fixed network

In today's digital age, broadband has become a necessity for each of us and every family. Without it, we would be restless and restless. So, do you know the technical principles behind broadband? From the earliest 56k "cat" dial-up to the current Gigabit cities and Gigabit homes, what kind of changes has our broadband technology experienced? In today’s article, let’s take a closer look at the “Broadband Story”. Have you seen this interface between █xDSL and ISDN? I believe that many friends born in the 70s and 80s must have seen it and are very familiar with it. That's right, this was the interface for "dial-up" when we first came into contact with the Internet. That was more than 20 years ago, when Xiao Zaojun was still in college. In order to surf the Internet, I
