AVIC Optoelectronics applies for patents related to connector fiber optics, with the connector and fiber optic connector featuring dual-key matching to prevent rotation stabilization and error-proof assembly.

On March 28, news from the National Intellectual Property Administration indicates that AVIC Optoelectronics Technology Co., Ltd. has applied for a patent titled "An Adapter and Optical Fiber Connector." The application publication number is CN121741942A, the application number is CN202610004315.6, the application publication date is March 27, 2026, and the application date is January 5, 2026. The inventors are Zhou Xiaojun, Zhang Zhi, Chen Xiaolin, Zhang Lei, Wang Lin, Tang Yang, and Hu Zhiguo. The patent agency is Luoyang Huaho Intellectual Property Agency (general partnership), and the patent agent is Yang Zhifeng. The classification number is G02B6/38.

The patent abstract shows that the invention belongs to the technical field of connectors, specifically involving an adapter and an optical fiber connector. The adapter includes a housing, a sleeve nested within the housing, and a ceramic tube nested within the sleeve. The walls at both ends of the housing are equipped with narrow keyways and wide keyways for identifying and fitting the narrow keys and/or wide keys at the ends of the optical fiber connector to achieve anti-rotation. The optical fiber connector includes a front sleeve, a rear sleeve positioned at the rear end of the front sleeve, and optical fiber contact components installed within the front and rear sleeves. The front sleeve is equipped with narrow keyways and wide keyways for identification and fitting with the end of the adapter to achieve anti-rotation. The dual keys on the optical fiber connector fit with the dual keyways on the adapter, providing better anti-rotation effect between the optical fiber connector and the adapter, effectively preventing the optical fiber connector from rotating, ensuring more stable performance during APC docking, and also preventing incorrect assembly.
