Description

[0001] Technical field: [0002] The invention relates to an active optical cable connector, in particular to an integrated, small size, light weight, anti-electromagnetic interference, high reliability, simple and convenient installation and debugging, and can completely solve the traditional pigtail type optical module disk fiber and The problem of easy breakage of optical fibers can greatly save the space volume of manned space systems, and is very suitable for active optical cable connector components for data transmission applications in manned space systems. [0003] Background technique: [0004] At present, the existing optical communication systems at home and abroad usually consist of optical modules at both ends of the transceiver, optical cable connectors, and transmission optical cables. As the modulation and demodulation end of the transmission signal, the optical module performs the function of photoelectric / electro-optical conversion of the signal. Optical modules, op...

AI Technical Summary

Problems solved by technology

[0007] 1. The gold finger electrical pin interface is a plug-in type. In the vibration and shock environment, the plug-in structure is prone to hidden dangers of poor contact. Therefore, when the gold finger electrical pin interface is used, the optical module can be used in a high-reliability application environment. The ability to resist vibration and shock is relatively weak, and the reliability cannot be guaranteed

[0008] 2. When the optical module is installed on the system circuit board, the system board needs to provide a larger space for the optical module to realize signal conversion and transmission. At the same time, because the optical fiber quartz glass material at the optical port of the optical module is easy to break, it is not suitable Excessive bending, so it has a minimum bending radius and needs to be coiled, which also occupies a large space, which is a large burden for manned spaceflight system engineering

[0009] 3. The interface between the optical fiber and the optical module is prone to fiber breakage and increased loss due to severe vibration and shock, thereby greatly reducing the transmission performance index of the optical module

[0010] 4. The separate structure makes the installation and debugging of optical modules, optical cable connectors and optical cables complicated and cumbersome
