Patent ID: 8172469

Claim:
An optoelectronic module, comprising: a body defining a cavity within which one or more components are disposed, the body connected to chassis ground; a signal ground; and an optical subassembly disposed in the body cavity and having one or more components connected to the signal ground, the optical subassembly comprising: a header assembly within which one or more components that generate electromagnetic interference emissions are housed, the header assembly including an optical aperture; a housing including a port and a barrel, the port defining a fiber receptacle and the barrel defining a cavity that at least partially receives the header assembly; an integral lens disposed within the cavity defined by the barrel; and a containment structure, connected to signal ground and to the header assembly, that at least partially shields the electromagnetic interference emissions within the optical subassembly, the containment structure defining a containment aperture that is smaller than the optical aperture, wherein: the one or more containment structures further comprise a containment disk configured to be connected to the signal ground; the containment disk is disposed between the integral lens and the header assembly; and the containment disk defines a containment disk aperture that is smaller than the optical aperture.
