ABSTRACT:
A shield device for preventing the emission of electromagnetic interference (“EMI”) from an optoelectronic device, such as an optical transceiver, is disclosed. In particular, an EMI shield is disclosed for placement within an optical transceiver module in order to intercept and absorb EMI produced by electronic components included within the transceiver. This absorption by the EMI shield prevents EMI from escaping the optical transceiver module and interfering with other electronic components that are typically placed in close proximity to the transceiver. The EMI shield in one embodiment includes a sheet of EMI absorbing material that is sized for placement within the transceiver. The EMI shield can be interposed between an outer shell of the transceiver and electronic components located on a printed circuit board that is disposed within the transceiver. The proximity of the EMI shield to the EMI-producing electronic components maximizes EMI absorption by the shield.
