Abstract: A method of fabricating a multi-core polymer optical fibre comprises arranging optical fibre preforms in a stack, the optical fibre preforms each comprising a polymer core and polymer cladding surrounding the polymer core; and drawing and bonding the stack to form the multi-core polymer optical fibre. Any contaminants or impurities which collect on outer surfaces of the preforms may be confined to boundaries between the preforms, which may avoid attenuation of signals passed through the cores while at the same time reducing crosstalk between cores of the final manufactured fibre. Also provided is a multi-core polymer optical fibre obtainable by the method.

Abstract: A system for using free-space optics to interconnect a plurality of computing nodes can include a plurality of optical transceivers that facilitate free-space optical communications among the plurality of computing nodes. The system may ensure a line of sight between the plurality of computing nodes and the optical transceivers to facilitate the free-space optical communications. The line of sight may be preserved by the position or placement of the computing nodes in the system. The position or placement of the computing nodes may be achieved by using different shaped enclosures for holding the computing nodes.

Abstract: An application programming interface (API) supporting server and key based networking is described. In an embodiment, the API receives either a key or a server address from a service running on a server in a direct-connect topology and returns data which identifies suitable next hops for transmission of a packet of data which has a destination of the received server address or of a server address which is encoded within the received key. In another embodiment, the key also encodes information specifying alternative server addresses for use in the event that the original server is unreachable. This information may also be used to define servers for replication of the key. A further embodiment describes a method of queuing packets for transmission against multiple links, where the packet is transmitted on the first available link and at this time is removed from the queues for the other links.

Abstract: A switching network for effecting point-to-point communication between nodes has a time-varying switching configuration, which causes successive activation and deactivation of multiple channels of the switching network, a first of the channels connecting, when activated, a transmitter node and a first receiver node, and a second of the channels connecting, when activated, the transmitter node and a second receiver node. In a training phase, a method comprises: transmitting from the transmitter node via each channel a known training signal, to cause each receiver node to receive a distorted training signal, using the first distorted training signal and knowledge of the first known training signal to determine respective one or more transmit-side equalizer (EQ) coefficients for each channel, and storing, in memory accessible to the transmitter node, the first transmit-side EQ coefficients, in association with each channel, for use in conducting scheduled communications over the switching network in a communications phase.
