摘要：
The present invention provides an optical transmission module comprising: a laser diode; a lens for condensing a laser beam from the laser diode; a fiber ferrule which is placed so that the laser beam condensed by the lens can enter a fiber core; and a lens aperture or a lens aperture portion which is provided at one of the lens itself, a position before the lens and a position after the lens.In addition, the present invention provides an optical transmission module in which instead of the lens aperture, an effective diameter of the lens on the fiber ferrule side is set at a value ranging from 0.1 times to less than 0.2 times of a distance between an emittance plane of the lens and an incidence plane of the fiber ferrule.
