Abstract: The invention is a datacenter network comprising a plurality of switches. The switches comprise edge switches and aggregation switches associated with sliceable bandwidth variable transceivers (S-BVT). An intermediate passive optical layer is communicatively coupled to the edge switches and the aggregation switches via fiber optic links associated with the S-BVTs. Furthermore, the intermediate passive optical layer is inserted between the edge and aggregation layers in order to combine the signals from each tier. The intermediate passive optical layer comprises a passive fiber coupler that combines the links between switches and each S-BVT receiver receives the signals sent from all S-BVT transmitters connected to the intermediate passive optical layer. The datacenter network is adapted to adjust the local oscillator wavelength of each S-BVT receiver and the wavelength and slice allocation of each S-BVT transmitter, thereby permitting dynamically allocating different resources to each link.

Abstract: Embodiments are disclosed for a quantum key distribution enabled intra-datacenter network. An example system includes a first vertical cavity surface emitting laser (VCSEL), a second VCSEL and a network interface controller. The first VCSEL is configured to emit a first optical signal associated with data. The second VCSEL is configured to emit a second optical signal associated with quantum key distribution (QKD). Furthermore, the network interface controller is configured to manage transmission of the first optical signal associated with the first VCSEL and the second optical signal associated with the second VCSEL via an optical communication channel coupled to a network interface module.

Abstract: A network device includes an enclosure, a multi-chip module (MCM), an optical-to-optical connector, and a multi-core fiber (MCF) interconnect. The enclosure has a panel. The MCM is inside the enclosure. The optical-to-optical connector, which is mounted on the panel of the enclosure, is configured to transfer a plurality of optical communication signals. The MCF interconnect has a first end coupled to the MCM and a second end connected to the optical-to-optical connector on the panel, for routing the plurality of optical communication signals between the MCM and the panel.
