What is the fiber optic cable specifically?

An optical fibre cable is a communications cable consisting of two or more glass or plastic fiber cores that are placed in a protective coating and covered by a plastic PVC outer casing. Signal transmission along internal fibers typically uses infrared. In January 2013, Cuba made a communication revolution, and the opening of fiber-optic cables to increase foreign channels attracted attention.

 

China began research on fiber optic cables from the mid-1970s, starting almost at the same time as abroad, and developed the first quartz fiber in early 1977. Driven by the demand for large-scale communication construction in China, China's fiber optic 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 fiber optic cable companies have also grown rapidly, and product development capabilities and technological innovation capabilities have been further enhanced. China has become the world's second largest fiber optic cable country, and all aspects have reached the world's advanced level.

From January to November 2007, China's optical fiber and optical cable manufacturing industry realized a total industrial output value of 29,771,661 thousand yuan, an increase of 33.22% over the same period of the previous year; cumulative sales revenue of products reached 28,422,739 thousand yuan, an increase of 38.13% over the same period of the previous year; The total profit was 1,785,178,000 yuan, an increase of 63.34% over the same period of the previous year.

China's fiber optic cable industry will maintain a steady growth trend with the in-depth development of China's village-to-project, the irreversible trend of light-incoming copper (the replacement of copper cables by optical cables) and the role of the World Expo in the information economy. What is more worthy of attention is that the large-scale construction of 3G and the gradual launch of FTTH will become the long-term driving factor for the development of China's fiber optic cable industry, which will definitely push China's fiber optic cable industry into a new round of growth cycle.
