Patent abstract
An optical receptacle for an optical subassembly is disclosed. The receptacle includes a sleeve made of brittle insulating material, for instance, a ceramics to electrically isolate the housing of the receptacle from the package for a semiconductor device. The receptacle disclosed has an arrangement that prevents the sleeve, even made of brittle material, from cracking. A portion of the sleeve is press-fitted into the housing, while, the metal stopper is press-fitted into another portion of the sleeve, which is apart from the former portion. Accordingly, the sleeve may be escaped from receiving the pressure from both the inside and the outside at the same time, which prevents the sleeve from cracking.
