Zhao Zisen 1983 worked as the chief engineer in the Research Institute of Wuhan University of Posts and Telecommunications, 1985 he took the post of vice president. Such a busy post has not weakened his research and love for optical fiber communication.
So, he continued to work hard and made great efforts to lead a group of scientific and technological personnel to complete the first optical fiber communication system project with a capacity of 34 megabits per second in China, that is, the "Hanjingsha Project" that we often hear. This system has played an extremely important role in transforming China's 6,543,800 km open wire into overhead optical fiber line, and its economic value is immeasurable, so it is also known as "the father of China optical fiber".

Scientific American magazine once commented: "Optical fiber communication is one of the four most important inventions since World War II. Without optical fiber communication, there would be no Internet and communication network today. " However, little known is that Academician Zhao Zisen pulled out the first optical fiber in China and the birth of the first optical fiber.
There are several important node events in optical fiber communication: 1966, Gao Kun, an English/American Chinese born in Shanghai, first proposed that glass fiber can be used for communication.
1970, the United States spent $30 million to manufacture three 30-meter-long optical fiber samples, which is the first time in the world to manufacture optical fibers with practical value for optical fiber communication. Seven years later, Zhao Zisen, a young teacher living in Wuhan, also pulled out the first practical optical fiber with independent intellectual property rights in China.
