For too long, we have ignored the technology that has served us so well in the Internet age: fiber optic communications.To send messages online, of course, you need not only a mobile phone with a signal, but also this fiber-optic communication, which acts as an intermediary for the transmission of information.Maybe this is still hard for you to understand.In fact, optical fiber communication is similar to an experiment we often do when we are children, two cups are tied together by a string, and then two people stand on both ends respectively. One person speaks into the cup, and the other person's ear is close to the cup, so that they can hear the message conveyed by the other person.Fiber optics, which carry more than 90 percent of the Internet age's traffic, are the equivalent of the rope in this experiment.Fiber optics carry over every aspect of the 5G space that we're talking about right now.In 1966, optical fiber was born as a concept in the hands of Charles Kao, the "father of optical fiber". In 2009, the 100G digital coherent optical communication system was successfully launched, which fired the first shot in the field of optical communication.And from 100G to the world record of 800G today, not without the contribution of Zhuge Qunbi, a great scholar."The signal transmission behind your WeChat may be processed by the algorithm I designed."At the end of last year, Zhuge Qunbe's name appeared on the list of "35 Under the Age of 35 Scientific and Technological Innovators" in China 2020. His innovation achievements have helped increase the single wave speed of optical communication from 100G to 800G, which is not to be underestimated.

In 2017, among the overall shipments of global optical network, the total number of high-speed ports with 100G or above was more than 120,000, and Huawei accounted for 3/1.At that time, Huawei's 200G was already relatively mature, and the commercialization of 400G and 600G was near at hand.As a result, in 2018, Huawei brought a surprise to the outside world, the industry's first single wave 600G ultra-high speed transmission product through the way of live demonstration.Back in 2011, the single-channel rate was 400Gbit/s or 1-Tbit/s, requiring new technologies, and everyone was worried about this tipping point.However, from 100G to 400G, and then to the current 800G, China's optical communication field is incredibly strong and resilient. In less than ten years, China has made such achievements like a complete success.With the gradual deepening of the 5G era, we can foresee that the scenes from science fiction movies in real life will not be far away.
