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.
