Domestic optical fiber is close to the international leading level Market positioning is very important

In recent years, the main optical fiber used by China's optical fiber and cable enterprises has been very close to the international leading level, and the main difference in the development of optical fiber and cable at home and abroad is that optical fiber and cable manufacturers have invested insufficient R&D funds, manpower and material resources in medium and long-term products and technologies, and the development is relatively slow
.
Jiang Xinli, chief technology officer of Zhongtian Technology, said that if China's optical fiber and cable manufacturers want to enter the international market, they need to accurately position
different foreign markets according to various situations.

Jiang Xinli pointed out: In the past, optical fiber and cable products were produced according to ordinary standards, and when the backbone network evolved to 400G, the loss of optical fiber had an increasing
impact on the entire system.
In this case, it is urgent to support low-loss large-effective area and ultra-low-loss large-effective area optical fibers, and at the same time, it is necessary to improve the consistency of optical fiber and cable performance parameters, and produce in accordance with strict standards to prevent problems that are difficult to control
.
Recently, Zhongtian Technology has invested more manpower and material resources, especially the addition of many R&D equipment, but now the demand for centralized procurement of domestic operators is not obvious, in addition, the manufacturing cost of ultra-low loss optical fiber is very high, and the yield rate is very low
.
These factors have led to relatively slow
progress in the development of ultra-low-loss optical fibers.

The manufacturing cost of the general fiber core layer is 5 times that of the outsourcing material, and the increase in the cost of low-loss large-effective area optical fiber is due to the increase in the diameter of the core layer, although the cost of low-loss large-effective area optical fiber is higher, but if it is mass-produced, the cost can be increased by about 40% compared with ordinary optical fiber, but the cost of small batch production will be higher than 40%.
