A network element and a method for propagating data packet from an input port of a network element to an output port of the network element, the network element comprising a plurality of input ports and a plurality of output ports interconnected by an optical switch, the method including the steps of: receiving the data packet at an input port; processing the data packet to determine a destination output port out of the output ports of the network element; partitioning the data packet to a plurality of fixed sized cells; for each fixed sized cell of the data packet: optically transmitting in parallel optical signals to an optical switch, the optical signals being representative of all the bits of a fixed sized cell, switching the optical signals across the optical switch in view of the destination output port, during a single switching cycle, and converting the optical signals to electrical signals being representative of the fixed size cells; accumulating electrical signals being representative of fixed sized cells of the same data packet to provide a data packet; and providing the data packet to the destination output port.
