Optical Fiber Connection Component Alignment During End-Face Grinding

The patent applies preliminary action by performing rotational alignment of the optical fiber before grinding. The fiber is rotated to the correct azimuth position while still held by the first holding member, and this aligned position is preserved through the grinding process. By establishing the correct core position before the grinding operation, the subsequent grinding that flattens the end face does not cause positional deviation, thus resolving the contradiction between achieving flat end faces and maintaining core position accuracy.

The patent applies self-service by utilizing the optical fiber itself as the alignment reference. The fiber's own structural features (such as asymmetric markings or refractive index variations) are used to determine the correct rotational position during alignment. This eliminates the need for external alignment tools or complex measurement systems, thereby achieving high core position accuracy while minimizing process complexity.

The patent applies merging by combining multiple bonding operations into a single integrated step. Instead of performing separate bonding operations for different sections of the fiber or different holding members, the process combines these operations so that bonding agents are applied and cured in a unified manner. This reduces the total number of process steps and drying/curing cycles required, thereby maintaining strong connections while reducing manufacturing time.
