Patent ID: 8666258

Claim:
A receiver optical subassembly (ROSA) comprising: a plastic body comprising: a barrel; and a nose piece defining a port configured to optically connect the optical receiver to a fiber-ferrule disposed within the port; an optical receiver disposed within the barrel; and an electromagnetic interference (EMI) shroud including a thin piece of material with EMI shielding properties wrapped around an exterior of the plastic body, wherein: the EMI shroud substantially covers the length of the barrel; the EMI shroud completely surrounds the portion of the length of the barrel within which the optical receiver is disposed; a first end of the EMI shroud overlaps with a second end of the EMI shroud where the first end and the second end mate; and the EMI shroud is configured to provide EMI shielding for the ROSA that is substantially similar to EMI shielding that would be provided by the plastic body if the plastic body were made of metal without the EMI shroud being grounded to a housing of an optoelectronic transceiver within which the ROSA is disposed.
