Fiberhome communication overcomes "low-loss and bending-resistant optical fiber technology"
Optical fiber preform is an important basic material for making optical fiber and optical cable, which is known as the "crown jewel" of optical communication industry, accounting for more than 70% of the profits of optical fiber and optical cable industry chain. However, the G.652 single-mode optical fiber preform used for wire drawing in China's optical fiber enterprises has always relied on imports.
In order to solve the technical bottleneck of optical fiber preform in China, Fiberhome Communication analyzes the development trend of optical fiber communication technology in China, and thinks that after the completion of backbone network and metropolitan area network construction, broadband access network construction will be the only way for optical fiber broadband network.
The construction of access network is facing new and severe challenges: the construction environment is no longer a wide venue, but a narrow space such as dense residential areas. Optical fiber often encounters a cruel bending state with a small radius, with large bending loss, large optical signal loss and unreliable optical transmission. Therefore, it is necessary to develop optical fiber with good bending performance to meet the new requirements of access network construction.
The construction of backbone network and metropolitan area network is like the artery of human body, and the access network is like the capillary of human body. The demand of this kind of optical fiber will exceed that of single-mode optical fiber, and it will gradually replace G.652 optical fiber and become the mainstream of optical fiber technology in the future. Therefore, Fiberhome Communication has chosen "low-loss bending-resistant optical fiber technology" as its main direction.
However, the "two-step" manufacturing process originally applied to G.652 optical fiber preform is not suitable for the manufacture of this new type of optical fiber, and a series of technical problems are encountered. For this reason, Fiberhead people have quietly carried out their own research, used decades of technical precipitation and accumulated experience, and established the "TS-SEED optical fiber technology system" through hard research and independent innovation with national experts.
The system includes three-step optical rod technology (TS), waveguide structure (S), enhanced bending (E), equipment (E), wire drawing deuterium (D) and other core technologies, which is called TS-SEED optical fiber technology system for short.
