Description

Self-aligning optical fiber connector
Technical Field
The utility model relates to an optical fiber connection technical field especially relates to an automatic alignment optical fiber connector.
Background
The optical fiber connector is a device for connecting and disassembling an optical fiber communication line, the optical fiber connector can be in compression joint with the end faces of two optical fibers, the transmission loss of an optical path is reduced, and the reliability of optical fiber transmission can be influenced if the end faces of the two optical fibers are in butt joint accurately. The mode field diameter of the single-mode fiber is much smaller than that of the multimode fiber (for most communication optical fibers, the mode field diameter is approximately 1/5-1/6, for example, the typical diameter of the core of a standard single-mode fiber is about 9 μm, and the diameter of the core of a standard multimode fiber is generally 50 μm or 62.5 μm), so that the alignment accuracy requirement of the single-mode fiber is much higher than that of the multimode fiber, and thus, the ferrule accuracy used by the conventional single-mode fiber connector is much higher than that used by the multimode fiber connector. In order to ensure that a single-mode optical fiber connector meets the requirements of relevant indexes of industrial standards in the manufacturing process, currently, ferrules with different precision requirements are used for single-mode and multi-mode optical fibers respectively in the field of optical fiber connector manufacturing, namely, the ferrules for the multi-mode optical fiber connector and the ferrules for the single-mode optical fiber connector are distinguished. The single mode/multimode ferrule used by the optical fiber connector looks the same in appearance and structure, but the single mode ferrule has high requirements on the relevant dimensions of the ferrule, especially the requirement on the concentricity precision of the inner bore diameter of the ferrule and the outer cylinder is very high (generally within 1.5 micrometers, in order to meet the requirement on ultra-low insertion loss during butt connection, the precision is even controlled at a submicron level to be less than 1 micrometer), and the most direct result of the high precision requirement is that the high cost/price of the single mode ferrule leads to the high cost of the single mode connector, and is particularly prominent for the ultra-low loss connector, and the ferrule cost is almost doubled. Therefore, conventional ferrule configurations cannot use low-precision (e.g., precision equal to or less than that of multi-mode ferrules) processes to produce high-precision connected single-mode fiber optic connectors.
