Abstract: The present invention relates to a Power over Ethernet system (100) which supports additional optical communication via optical fibres. The powered devices (d1, d2, d3) may comprise circuitry to process optical signals, in particular triggering activation of the powered device (d1, d2, d3) after being in a low power state. The power supplying devices (s1-s6) may relay optical signals via direct optical paths. Optical paths in the network may improve timing accuracy of applications. The overall power consumption of the system may be improved in particular during low activity situations in which the system is primarily used for data communication. The additional optical communication paths may provide redundant paths and thus may increase the network's robustness.

Abstract: Switching technology may be incorporated into various systems, components, and/or architectures in a fiber optic network to promote network reconfigurability and design flexibility. A signal access unit comprises an input, an output, an access port, a switch arrangement including a switch, and a controller. The switch optically couples the input to the output and not to the access port when in a first configuration, and optically couples the access port to at least one of the input and the output without optically coupling the input and the output together when in a second configuration. The controller is configured to receive an indication of a selected wavelength and to operate the switch arrangement to change the switch between the first and second configurations based on the indication of the selected wavelength.

Abstract: A network system for a data center is described in which a switch fabric provides full mesh interconnectivity such that any servers may communicate packet data to any other of the servers using any of a number of parallel data paths. Moreover, according to the techniques described herein, edge-positioned access nodes, permutation devices and core switches of the switch fabric may be configured and arranged in a way such that the parallel data paths provide single L2/L3 hop, full mesh interconnections between any pairwise combination of the access nodes, even in massive data centers having tens of thousands of servers. The access nodes may be arranged within access node groups, and permutation devices may be used within the access node groups to spray packets across the access node groups prior to injection within the switch fabric, thereby increasing the fanout and scalability of the network system.
