To handle the optical fiber end and linker grinding, need to rely on advanced technology equipment and exquisite technology. First of all, the high-precision grinder is used to grind the optical fiber end slightly to ensure the smooth and smooth end surface. Next, polishing is performed with specially designed polishing tools to eliminate subtle scratches and irregularities. For the linker, a special grinding and polishing process is used to ensure its accurate docking with the optical fiber end. Throughout the process, the precise control system and on-line detection technology ensure that every step is accurate.

Fiber optic gyro, or FOG, is a high precision instrument using optical fiber technology. It works intuitively, like "dancing" light in a fiber. When light travels through the fiber, the propagation path in it also changes if the fiber rotates. By accurately measuring this change, the optical fiber gyro can calculate the rotation speed and direction of the optical fiber. The key of fiber optic gyro lies in its high-precision optical system and electronic signal processing system. The optical system ensures that the light travels stably through the optical fiber, while the electronic system is responsible for receiving and processing the optical signals to obtain accurate angular velocity data. Due to its high sensitivity, rapid response and long-term stability, FFG has been widely used in aviation, aerospace, navigation and other fields, providing an important means of angular velocity measurement for navigation and control systems.
