Nanjing Chunhui Technology Industrial Co., Ltd. was established in 1997. Its predecessor was the Third Research Institute of Nanjing Glass Fiber Research and Design Institute of the State Building Materials Administration. As early as the mid-1970s, under the leadership of Academician Zhang Yaoming, he began to study non-communication optical fibers. After more than 40 years of hard work, the company has a series of products such as "multi-component glass optical fiber", "quartz optical fiber", "polymer optical fiber", "liquid core optical fiber", optical fiber, electronic endoscope and other series of products. Manufacturing and application technology, its technological level has always been at the international and domestic advanced level, and has been recognized by the State Science and Technology Commission as "National Engineering Technology Research Center - Non-communication Optical Fiber and Product Technology Development Base".
