A coherent optical receiver module and a method for manufacturing the same are disclosed. The module includes a housing, an optical fiber group, a first optical element, and a second optical element.The housing stores a first optical component disposed on an optical path of a local beam and a second optical component disposed on an optical path of a signal beam. The optical fiber group includes afirst optical fiber optically coupled to the first optical component and a second optical fiber optically coupled to the second optical component. The first optical element has a first lens disposedon the optical path of the local beam, and transmits the signal beam and the local beam. The second optical element has a second lens disposed on the optical path of the signal beam, and transmits thesignal beam and the local beam. The first optical element and the second optical element are placed side by side between the optical fiber group and one end surface of the housing. 本发明披露种相干光接收器模块及其制造方法。该模块包括壳体、光纤组、第光学元件和第二光学元件。
