Fasen Company is the only optical fiber preform manufacturer with independent intellectual property rights in China. Mitsuko Mori Company was established with Australian National Optoelectronic Research Center with world-leading technology, and the production technology of MCVD plus OVD hybrid optical fiber preform with independent intellectual property rights was developed, and the first domestic standard of G.652 optical fiber preform was formulated, realizing large-scale production, and the product quality reached the international advanced level, breaking the technical lock of optical fiber giants such as Corning, Nortel and Alcatel. The profit ratio of optical cable, optical fiber and optical fiber preform is 1∶2∶7. Whoever takes the lead in mastering the production technology of optical fiber preform will have the initiative in the market. At present, there are 12 large-scale optical fiber manufacturers in China, and it is expected to purchase some optical fiber preforms from Fasen in the future, which means that the company will obtain the most lucrative industrial profits. In order to consolidate the market position, the company is currently accelerating the research and development and commercial production of new special optical fiber products. It is estimated that the annual production capacity of optical fiber preform will reach100t, with an annual output of 3 million core kilometers of optical fiber and a sales income of 750 million yuan, making it a well-deserved optical fiber leader in China. At present, China's IPv6 network has been opened, and 3G communication is expected to enter a comprehensive construction period. At the same time, with the popularization of ADSL, IPTV and other services are expanding rapidly, and a large number of demands fully reveal the great development opportunities of the optical communication industry. As a domestic optical fiber leader, Farson will greatly benefit.
