Abstract
A system for retaining an optical subassembly in a shell of a communications module is disclosed. The system reduces stress imposed on a hermetic package of the optical subassembly during lead interconnection procedures while ensuring thermal contact of the package with a thermal pad mounted in the shell. In one embodiment, the system includes a spring clip comprising a head portion that defines a seating surface, as well as first and second arms. The seating surface is shaped to engage an outer surface of a nosepiece of the optical subassembly. The first and second arms extend from the head portion so as to define a “U”-shaped configuration with the head portion. The head portion is shaped so as to provide a resilient force against a flange of the nosepiece when the flange and spring clip are received in a groove defined in the shell during assembly.
