China started the research of optical fiber and cable in the mid-1970s, almost at the same time as foreign countries, and developed the first quartz optical fiber in early 1977. In recent years, driven by the demand for large-scale communication construction in China, China's optical fiber and cable industry has developed rapidly, and has formed a complete industrial chain from optical fiber preforms to optical cable products. The production and technical strength of China's optical fiber and cable enterprises has also grown rapidly, and their product development ability and technological innovation ability have further improved. China has become the second largest fiber optic cable country in the world, reaching the world's advanced level in all aspects. From January to November 2007, the total industrial output value of China's optical fiber and cable manufacturing industry was 29771661000 yuan, an increase of 33.22% over the same period of the previous year; The accumulated product sales revenue was 2842273900 yuan, up 38.13% over the same period of the previous year; The accumulated total profit was 178517800 yuan, an increase of 63.34% over the same period of the previous year. With the in-depth development of China's village access project, the irreversible trend of optical fiber entering copper and retreating from copper (optical fiber cable replacing copper cable), and the pull of the World Expo on the information economy, China's optical fiber and cable industry will maintain a steady growth trend. More importantly, the large-scale construction of 3G and the gradual start of FTTH will become the long-term driving factors for the development of China's optical fiber and cable industry, and will certainly push China's optical fiber and cable industry into a new round of growth cycle.
