Abstract: A connector assembly is disclosed for interconnecting high speed data transmission cables across an interface panel to an external circuit. A first pin array of conductive pins is carried by an input face and a corresponding second pin array of conductive pins is carried by an output face of a panel connector. An array of conductive sockets corresponding to the second pin array is carried by a plug front of a plug connector for receiving the second array of pins when connectors are mated together. A third pin array of conductive pins is carried by plug back corresponding to the first pin array. In this manner, a first set of transmission cables electrically connected to the first pin array of the panel connector is electrically connected to a second set of transmission cables connected to the third pin array of the plug connector.
