    • A light emitting module according to the present invention is characterized in that a light emitting device and a light-emission-side lens are held close to each other by a holding part extended from part of a stem in parallel with outgoing light of the light emitting device, and light emitted from the light emitting device is refracted. A single-fiber two-way optical communication module according to the present invention has the light emitting module and, in addition, collimate lenses close to an optical fiber and a light receiving device, and is characterized in that splitting of light to a light receiving module or coupling of light from the light emitting module is performed with parallel rays. Each of the collimate lenses condenses the parallel rays to an incident/outgoing end face of the optical fiber, condenses the parallel rays to a light receiving face of the light receiving device, and outputs, as parallel rays, outgoing light from the light emitting module.
    • 根据本发明的发光模块的特征在于,发光器件和发光侧透镜通过从杆的一部分延伸的保持部分彼此靠近地保持,所述保持部分与发光的发射光平行 装置,并且从发光装置发射的光被折射。 根据本发明的单纤双向光通信模块具有发光模块,另外,准直透镜靠近光纤和光接收装置,其特征在于,将光分成光接收 使用平行光线进行来自发光模块的光的模块或耦合。 每个准直透镜将平行光线聚光到光纤的入射/出射端面,将平行光线会聚到光接收装置的光接收面,并且作为平行光输出来自发光模块的出射光 。
