Abstract
Abstract A screening arrangement is provided for attachment to the rear (5) of a connector (1) having one or more poles (3) for receiving an optical fibre (4). The screening arrangement comprises a conductive housing (6) and a conductive sleeve (12) for the or each optical fibre (4). The or each conductive sleeve (12) is electrically connected to the conductive housing (6) and acts as a waveguide attenuator. The conductive housing (6) is closed, for instance by transverse plates (9, 10), about the conductive sleeve or sleeves (12) so as to form a Faraday cage on the rear of the connector (1) pierced only by the waveguide attenuators (12).
