Abstract: A power plane structure for a printed circuit board includes a copper layer, and a carbon layer applied directly to a surface of the copper layer. The carbon layer can include graphite or graphene. In additional embodiments, a duplicate power plane structure for a printed circuit board includes two power planes separated by an insulating core, each power plane including a copper layer and a carbon layer applied directly to a surface of the copper layer.

Abstract: A structure includes a first copper layer and a first carbon layer applied directly to a surface of the first copper layer, a second copper layer and a second carbon layer applied directly to a surface of the second copper layer, and an insulating core disposed between the first and second copper layers. Each of the first carbon layer and the second carbon layer faces toward and directly contacts the insulating core. The structure provides electrical power to a component of an electronic device.

Abstract: A conductive signal transmission structure for an electronic device (e.g., a printed circuit board of an electronic device) includes a copper material and a graphene layer disposed within the copper material at a depth below a surface of the structure. The depth of the graphene layer is further within a skin depth region of the structure when a transmission signal applied to the conductive signal transmission structure has a signal speed of at least 112 Gbps.

Abstract: A method in which a plurality of transmit signals are generated at data rates that are offset from each other by inserting an idle data block into a data stream for one or more transmit signals of the plurality of transmit signals to increase a data rate for the one or more transmit signals, thereby minimizing detectable electromagnetic interference at a particular frequency. The method further includes converting each transmit signal of the plurality of transmit signals to a corresponding optical transmit signal of a plurality of optical transmit signals for transmission via a corresponding channel of a plurality of channels of an optical network device and transmitting the plurality of optical transmit signals via respective ones of the plurality of channels for transmission on respective optical fibers.
