An optical module with some OSAs and a fiber unit is disclosed. The fiber unit includes a stub and a flange. A portion of the stub extrudes from the flange; while, the housing of the module that assembles the OSAs includes a pocket with a diameter substantially equal to or slightly greater than a diameter of the stub. Setting the portion of the stub into the pocket, the fiber unit may be automatically aligned with the OSAs through the housing.
