A capacitive cable adapter for providing ground of the same potential at high frequencies for interconnected electrical devices. The capacitive cable adapter, for being interposed between at least two electrical devices interconnected via a shielded cable, comprises two shielded electrical connectors aligned back-to-back with an internal pin-to-pin connection, with the outer shield of each of the two connectors being interrupted approximately at mid distance between the end of the two connectors, thereby forming a gap between the outer protective shield of the two connectors, including a predefined number of capacitive components arranged such that, one of the two pins of each capacitor is connected to the protective shield of one of the two connectors, and the other pin of each capacitor is connected to the shield of the other connector, thereby connecting over the gap the outer shields of the two connectors.

Capacitive cable adapter

Data communications apparatus is described having a duplex SC connector comprising two parallel connection assemblies integrated into a single component for connecting two optical fiber cables with two optical fiber transceivers and a shielding structure arranged to, at least in part, reduce electromagnetic emissions from the optical fiber transceivers, characterised by a conductive member extending between the parallel connection assemblies, the conductive member being in conductive contact with the shielding structure at both sides of the duplex connector.

Data communications apparatus having improved shielding structure

A flexible capacitor (1) includes a dielectric made of flexible material, coated on each side with conductive material for insertion between a cable shield being at the ground potential of a remote electrical machine, and a part on a local machine being at the local ground potential (3, 5, 2) for example at a connector (7) level.
