The Development Trend Of Fiber Closure


At the beginning of 2011, China Telecom took the lead in opening up the broadband speed-increasing project and clearly stated that it will focus on building FTTH, which has once again brought a great impetus to the domestic optical fiber industry. However, there are still some gaps between domestic manufacturers and some foreign companies in terms of optical fiber technologies, processes, and products, such as the production of optical fiber key raw materials, “optical fiber preforms”.

How to seize opportunities in the construction of optical network cities, increase market share, improve their own core technology levels and enhance their international competitiveness are major concerns for domestic optical fiber manufacturers. The domestic optical fiber manufacturers have already reached a consensus: three aspects of product performance, application mode, and raw materials, efforts to achieve independent innovation of optical fiber to meet the needs of optical network city construction.

The industrial chain of optical fiber mainly includes three production links: optical rod, optical fiber, and optical fiber. As we all know, 10 years ago, China's optical fiber industry has just started. Fiber optic cable manufacturers mainly rely on imported fiber optics for optical fiber cable sales. Many key technologies are monopolized by foreign companies. Since then, domestic optical fiber companies have rapidly achieved independent production of multiple types of optical fibers by importing foreign wire drawing equipment and light rods. Fiber closures and fiber optic cassettes have all been researched and produced, and they have begun to enter the key raw material optical fiber rods.

The development of technology has brought about a tremendous increase in the competitiveness of domestic manufacturers. Such as fiber closure, because of its high-tech content, high investment, high profit margins and other characteristics, in the optical fiber communications industry chain, the core parts and high-end links. Prior to this, domestic light rods had to be imported into Europe, the United States, Japan, and other countries, and their high prices greatly limited the domestic market competitiveness of optical fiber. At present, many domestic optical fiber companies gradually realize the self-production of some light rods through large investments and have broken foreign technology and price monopoly.
