In one example embodiment, an optoelectronic module comprises a body, a signal ground, and an OSA. The body is connected to chassis ground and defines a cavity within which one or more components are disposed. The optical subassembly is disposed in the body cavity, has one or more components connected to signal ground, and comprises a header assembly, a housing, and one or more containment structures. The header assembly houses one or more components that generate EMI emissions and includes an optical aperture. The housing includes a port and a barrel. The port defines a fiber receptacle and the barrel defines a cavity that at least partially receives the header assembly. The containment structure(s) at least partially contain the EMI emissions within the OSA.

Electromagnetic interference containment structures

This disclosure is generally concerned with optical modules. In one example, an optical module provided that includes a pair of optical subassemblies, each of which includes a port housing within which a corresponding optical component is disposed. The optical module further includes a pair of electrically conductive elements configured to facilitate control of EMI. Each of the electrically conductive elements is disposed on a respective port housing such that a gap is present between the first and second electrically conductive elements and the first and second electrically conductive elements do not contact each other.

Simplex port cap EMI shield

An optical module has port housing comprised of a material that does not substantially shield EMI, such as an optical plastic. The port housings have a receiving ferrule disposed in an aperture of an electrically conductive shell. The ferrule is movably coupled to the shell to permit it to respond to loads imposed by an optical fiber connector and includes an electrically conductive cap to shield a portion of the port housing proximate the ferrule.
