英文摘要	The present invention provides an optical receptacle that reduces the fluctuation of the optical coupling efficiency with the optical plug. The optical receptacle of the invention comprises a stub with a filler therein and a sleeve assembly to receive the optical plug. The stub with a cylindrical shape has an opening in the side where the optical plug is to be in contact thereto and a bore in the other side. The diameter of the opening is comparable to that of the core of the external fiber, while the diameter of the bore is greater than that of the opening. The filler exposes in this opening to couple with the external optical fiber. Thus, the optical coupling efficiency between the filler and the external fiber may enhance and the fluctuation thereof due to the insertion/extraction of the optical plug can be reduced.
