A connector (20) has one part (22) which provides an electrical connection and another part (21) providing an optical connection. A single set of pins (24) connects the connector to its circuit. The connector (20) includes a circuit (26-29) allowing a channel of communication on a motherboard to be connected either electrically or optically. Additionally, a signal may be provided back to the motherboard to indicate which means of connection is employed. A mechanism (21) receives and holds in place optical fibres, and a socket (22) receives an electrical plug. A printed circuit board (26) is fitted with pins (24) to allow connections to be made to a motherboard. The electrical contacts (23) connect the appropriate points on the printed circuit board to the electrical plug, when it is inserted. Opto-electrical components (29) have their leads connected to the printed circuit board (26), so that when optical communication is required the signals can pass through these components. Short pins (28) are mounted on the printed circuit board (26) approximately in-line with some of the contacts (23) and in such a position that the ends of the contacts (23) touch the corresponding pins (28) when there is no electrical plug in the cavity. Other electronic components (27) as required are also mounted on the printed circuit board (26).
