Abstract

A connection system which includes fiber optic data links comprises a connector plug at the end of fiber optic cables and a mating header connector which house electro/optical devices and which is mounted on a printed circuit board. The header connector makes optical connections between the fiber optic cables of the plug connector and the electro/optical devices and electrical connections between the electro-optical devices and the circuitry of the printed circuit board. The header connector also includes a row of terminals for making purely electrical connections for electric cables which are terminated in the connector plug.
