The bending fiber optic technology is known as the pearl in the crown of fiber technology. Because of its advanced technology, process complexity, and wide application, it is also known as the most anticipated big cake in the fiber market. Beacon Communication Technology Co., Ltd. broke foreign technology blockade and patent barriers, developed key technologies, manufacturing processes and complete sets of equipment, and once again occupied the commanding heights of new fiber new technology fields and markets.

Severe "low loss anti -bending fiber technology"

Although the hair -like thick quartz glass fiber, its size is small, but it carries the information that the world depends on, changing the communication and lifestyle of all mankind. More than 90%of the world's information is transmitted by optical fiber.

Since entering the 21st century, my country's broadband strategy will achieve at least 300 million fiber -to -house households, which requires the bending radius of optical fiber to reduce from tens of MM to MM levels. The conventional optical fiber curvature loss cannot meet the requirements. Global optical fiber technology experts are facing difficult problems: optical fiber not only has low loss, but also can be bent at will like cables.

The conventional optical fiber design technology achieves the ability to bend by improving the refractive index of the core of the fiber core. As a result, the optical fiber -bending capacity developed is limited, and it is difficult to adapt to the application needs of access to the access network such as fiber -to -households. If the backbone network and the urban area network are compared to the large arteries on the person, and the access network is like the capillaries on the human body. If the capillary is not smooth, the information cannot be quickly circulated. Therefore, beacon communication has selected "low -loss anti -bending fiber technology" as the main direction.

In order to solve the technical problem of decaying attenuation in the application of small bending radius, Li Shiyu, the leader of the beacon communication fiber technology, proposed the new type of fiber design method under the inner package layer to enhance the bending. This method can selectively adjust the leakage rate of a mode in the fiber, and better control the optical power distribution, thereby effectively improving the bending performance of the fiber.

This method breaks through the technical barrier of foreign giants by increasing the height of the refractive index of the fiber core, while avoiding the technical disadvantages of the increase in optical fiber attenuation caused by high mixing fiber, and realizing the bending radius of the single -mode fiber 2mm, which is better than the international. Commercial levels are 2 times. After the design of the lower concave inner bag is designed, optical fiber can be bent at will like cables. From professional manufacturers to ordinary people's homes, more people can better enjoy optical communication, and meet the needs of broadband infrastructure construction such as FTTX fiber households. The relevant invention patent based on this is more than 5 years earlier than the international optical fiber giants, so that my country has occupied the commanding heights of intellectual property rights in new types of anti -bending fiber, breaking the intellectual property right wall of key technologies such as optical fiber design.
