Fiberhome: fiber optic sensing with special technology through acceptance

Recently, Fiberhome Communication Technology Co., Ltd. undertook a major scientific and technological innovation project in Wuhan East Lake New Technology Development Zone - "Fiber Optic Sensing with special optical fiber key technology research and development and industrialization" passed the expert group acceptance, acceptance of the expert group gave the project Excellent evaluation, the highest level of project acceptance assessment. This marks a major breakthrough made in the development of fiber-reinforced PM fiber.

It is understood that this project is the first optical fiber project in Wuhan Donghu New Technology Development Zone since the establishment of a major scientific and technological innovation project and is the only optical fiber technological innovation project up to now. Therefore, the zone is very concerned about the technical research results and industrial transformation of the project. It not only requests quarterly progress reports on the project during project implementation, but also includes experts on financial investment, senior accountant audit and experts on optical fiber development , Optical fiber applications and advanced research in the field of optical fiber field acceptance of a number of technical experts, acceptance of the expert group not only examined the project implementation during the technical research and industrialization results, but also the project in the future implementation of a pre-assessment.

According to the report of the expert group test, the researchers of FiberHome have not only completed the original innovation of the narrow-polarization polarization maintaining fiber of 135 micrometers but also took the lead in realizing the commercialization of this type of optical fiber in the world, Performance improvements and applications have contributed to the development of special fiber market has brought a qualitative change, opened the fiber optic gyro polarization maintaining fiber market.

The small diameter PM fiber contains two relatively independent and interdependent daughter light rod processes for mandrel preparation and stress bar preparation. The two are merged together by drilling technology to form a PM fiber preform. The PM fiber passes through a unique waveguide structure The design and fiber coating structure design is then drawn into a thin PM fiber to create a high performance 135 micron PM fiber.

It is understood that on the basis of this technology, the project team has also developed for the first time in the world a new type of polarization maintaining photonic crystal fiber, which has successfully helped the development of China's high-performance fiber optic gyroscope for aerospace. For the first time, the appraisal given by the application unit has successfully developed the polarization-maintaining photonic crystal fiber used in aerospace optical fiber gyroscopes. The optical fiber has an all-temperature performance that is an order of magnitude higher than conventional polarization-maintaining fibers and has excellent radiation resistance, Meet the space with high-precision mini-fiber optic gyroscope development needs, directly promote the development of related models.

Experts at the meeting said that the project applied for 9 invention patents through key process technology innovations such as stress bar doping technology, mandrel technology, deep drilling, special optical fiber drawing technology and optical fiber wrapping system, and introduced 135 micron fine-grain polarization-maintaining optical fiber and Polarization-maintaining photonic crystal fiber has made outstanding contributions to the performance improvement and good application of high-precision fiber optic gyroscopes and completed the technical specifications stipulated in the project planning task book.

Through the project's evolution, FiberHome has combined the leading-edge microstructured fiber technology and polarization-maintaining fiber technology to form a series of key technological innovations, not only to develop the fine-grained polarization maintaining fiber technology with superior performance, but also to invent the fine polarization maintaining polarization Sub-crystal fiber, also developed with excellent performance of the optical fiber products, will continue to help "Internet +" for China's information and communication to provide efficient, secure and stable communications pipeline.
