The invention provides an optical module. The optical module comprises a substrate which is provided with a fixed part for placing a lens; the lens disposed in the fixed part; a laser disposed on the substrate, wherein the laser is used for transmitting a light signal to the lens. The gaps between the two symmetric sides of the lens and the fixed part are provided with fixing glue. The optical module reduces the position deviation of the lens attached to the fixing glue, and reduces the decrease, caused by the movement of the lens, of coupling efficiency. 本发明提供种光模块。本发明光模块，包括：基座，所述基座上设置有用于放置透镜的固定件；设置在所述固定件内的透镜；设置在所述基座上的激光器，所述激光器用于向所述透镜传输光信号；其中，所述透镜相互对称的两侧与所述固定件之间的间隙对称填充有固定胶。本发明减小了附着在固定胶水上的透镜发生的位置偏差，从而降低透镜移动导致的耦合效率下降。
