view of the plug 300 the basic format of the 8p8c connector is retained with the connections 328 the lateral power connections 324 326 occupy a clear area on the 8p8c connector there is a variant of a standard ethernet connector that uses a screened cover the plug and socket of the present invention in its keyed version fig1 prevents interconnection with such a standard connector the master version fig1 on the other hand fit with such a standard connector the power supply that is connected to the lateral power connectors 324 326 is current limited to a safe value under these conditions the optical fibre is shown as 314 and 316 the option exists to have a single fibre with a directional splitter if required this may be fitted within the plug or socket it is clear that though two fibres are shown here there is room for more fibres in this position if required the auxiliary data connections 354 356 can be used for a multiplicity of functions in one particular application for installation of this connector in a wall plate power and data distribution system these pins are used to obtain access to the internal circuitry within the wall plate to allow for programming and routing information to be accessed and uploaded without the need for extra connectors to be fitted to the wall plate other uses for this connection is as a high power usb option other voltage supplies etc note that only two auxiliary data connections are shown in this area.
