光发射次模块及光收发组件
摘要：
本发明实施例公开了光发射次模块，包括棱镜主体、第一透镜和插件，所述棱镜主体包括入光端和出光端，所述第一透镜设于所述出光端和所述插件之间，所述插件包括接触端，所述接触端位于所述插件之远离所述第一透镜的表面，所述接触端的中心位于所述第一透镜的光路焦点上，所述接触端呈弧面状，以与光纤无间隙对接，减少所述接触端的端面反射。本发明还公开一种光收发组件。本发明实施例提供的光发射次模块具有较小的光纤端面的反射和回损。
摘要（英）：

Disclosed is an optical transmission sub-module, comprising a prism main body, a first lens and an insertion member, wherein the prism main body comprises a light incident end and a light-emitting end, the first lens is arranged between the light-emitting end and the insertion member, the insertion member comprises a contact end, the contact end is located on a surface, away from the first lens, of the insertion member, the centre of the contact end is located at a focus of an optical path of the first lens, and the contact end has a cambered shape so as to be butt-jointed with an optical fibre without a gap and reduce the end face reflection of the contact end. Further disclosed is an optical transceiver assembly. The optical transmission sub-module provided by the embodiments of the present invention has relatively small optical fibre end face reflection and return loss.
