Optical transmission module

The utility model provides an optical transmission module, it includes the module body, be equipped with laser instrument driver chip, laser instrument chip and control detector on the module body, control detector and laser instrument chip are all established in the place ahead of laser instrument driver chip's front end, and the rear end of laser instrument chip is towards laser instrument driver chip, be equipped with a speculum between the rear end of laser instrument chip and the control detector for the light reflex of sending laser instrument chip rear end is to the receipt face of control detector. Adopt above -mentioned structure, size that can the minimize module to the function of monitoring the detector is remain, laser instrument chip to distance between the laser instrument driver chip can also be shortened as far as possible. 本实用新型提供一种光发射模块，它包括模块本体，所述模块本体上设有激光器驱动芯片、激光器芯片以及监控探测器，所述监控探测器和激光器芯片均设在激光器驱动芯片的前端的前方，激光器芯片的后端朝向激光器驱动芯片，所述激光器芯片的后端和监控探测器之间设有一反射镜，用于将激光器芯片后端发出的光反射到监控探测器的接收面上。采用上述结构，能够尽量减少模块的尺
