An optoelectronic component, such as an optical transceiver, contains one or more optoelectronic devices, such as a semiconductor laser or a photodiode. It also contains a metallic or metallized housing within which the optoelectronic devices are mounted, and an optical connector part to allow optical radiation to be coupled between the optoelectronic devices and fibres of a fibre optic communications network. The optical connector is disposed at least partly within an aperture in the housing. A metallic or metallized barrier is disposed between the one or more optoelectronic devices and the optical connector substantially to shield against transmission of electromagnetic radiation through the aperture (except of course for the transmission of optical radiation to be provided to, or received from the fibre optic communications network). This barrier can be provided as part of a metallized clip, adapted to fit around the optical interface between the optoelectronic devices and the outside of the transceiver. The optoelectronic devices may be separated into an optical assembly and an electrical assembly, each with a separate conductive shield, in which case the metallized barrier may provide a part of the conductive shield for the optical components on the optical assembly.
