The present invention provides a high-tolerance fixing structure of an MT insertion core in an optical module structure, the MT insertion core and the MPO adapter are firstly installed in a matched mode, then the MPO adapter and the MT insertion core are integrally installed on the bottom shell, the clamping piece made of the conductive plastic material is clamped between the MT insertion core and the bottom shell, and then other structural parts are installed. The size control is simple, the optical end face positioning error of the MPO connector and the MT insertion core is reduced, and the electromagnetic shielding performance can be enhanced. 本发明提供了一种光模块结构中的MT插芯的高容差固定结构，将MT插芯先与MPO适配器配合安装，再将MPO适配器与MT插芯整体安装至底壳上，MT插芯与底壳之间卡入导电塑料材质的卡紧片，再安装其余结构件。使得尺寸控制简单，减小了MPO连接器与MT插芯的光端面定位误差，并能增强电磁屏蔽性能。
