Kunming manufactures or breaks the international monopoly of optical fiber production

The project of 30 tons of germanium tetrachloride tetrachloride production line implemented by Kunming Yungermanium High-tech Co.
, Ltd.
in the B-5-5 plot of Kunming New City High-tech Industrial Base is progressing smoothly and will be completed and put into operation
at the end of this year.
Recently, the reporter learned this news
from the First Bureau of Investment Promotion of the High-tech Zone.

The optical fiber germanium tetrachloride implemented by Kunming Yungermanium is a high-tech new material, which is a strategic emerging industry
supported by the state.
The total investment of the project is 30.
6 million yuan, the new construction area is 1935 square meters, and 129 sets of equipment and instruments are planned to be
purchased.
After the project is completed and put into operation, it is expected to achieve an annual sales revenue of 129.
29 million yuan and the tax paid will reach 6.
16 million yuan

Germanium tetrachloride is a dopant for preform cores
, the most important material in the optical fiber and cable industry.
It is understood that about 70% of China's preforms rely on imports, and foreign companies try in every possible way to monopolize China's optical fiber preform market
.
At the same time, with the continuous improvement of the demand for optical fiber varieties and specifications in the communication market, the requirements of optical fiber and cable companies for preforms are getting higher
and higher.
In the optical fiber industry, the profit of the production of optical fiber preform far exceeds the profit of the production of optical fiber cable, and at present, most of the manufacturers that can produce optical fiber on a large scale in China stay at the production level of imported preforms from abroad and domestic wire drawing processing, this model limits the cost reduction of optical fiber and hinders the development of the optical fiber industry, the main reason is that the core technology of foreign tightly sealed rod and the core technology
of manufacturing important raw materials such as germanium tetrachloride 。 To change this situation, it is necessary to solve the problem of localization of raw materials, improve the manufacturing process technology of optical fiber preforms, make breakthroughs in key areas of optical fiber production, and form a number of products
with independent intellectual property rights.

As a dopant for preform cores, germanium tetrachloride can improve the refractive index of the core, realize the total reflection, no loss and improve the transmission distance
of the optical fiber.
In recent years, the international demand for germanium tetrachloride for optical fiber has increased by more than 10% per year, and the demand for germanium tetrachloride for domestic optical fiber has increased at a rate of more than 20%, and China has become a global optical fiber preform production base
.

At present, the development and production of high-purity germanium tetrachloride are mainly concentrated in western developed countries, such as Umicore in Belgium and Alpha United Medical Co.
, Ltd.
in South Korea.

In China, only Beijing Guojinghui Company and Wuhan Yunjingfei Optical Fiber Material Co.
, Ltd.
produce germanium tetrachloride for optical fiber, and Wuhan Yunjingfei Optical Fiber Material Co.
, Ltd.
is a holding subsidiary
of Yunnan Lincang Xinyuan Germanium Industry Co.
, Ltd.

Facing the good demand prospect for optical fiber germanium tetrachloride in the development of optical fiber communication industry, Kunming Yungermanium gives full play to its capital, technical advantages and the formed industrial foundation, and builds an optical fiber germanium tetrachloride production line with an annual output of 30 tons and a purity of more than 99.
999%, increasing product varieties and enhancing market competitiveness
.

The completion of the project is conducive to extending the germanium industry chain, improving the added value of products, gradually replacing imported materials by expanding the production scale of germanium tetrachloride for optical fiber, entering the international market, and promoting the transformation and upgrading of enterprises; It is conducive to realizing the large-scale industrialization of germanium tetrachloride for optical fiber, promoting the development of China's germanium industry and independent innovation in optical fiber communication industry, enhancing the overall competitiveness of China's germanium industry and optical fiber communication industry, breaking technical barriers and blockades, and making products more competitive in the market
