We show on-demand multi-wavelength spectrum and space defragmentation in an SDM and elastic network with four programmable nodes and two multi-core fiber links. The combined approach is shown to reduce blocking and hardware requirements in small nodes.
In this paper, we propose and experimentally demonstrate simultaneous format and wavelength conversion of multiple fragmented signals suitable for gridless and multi-granular networks. Conversion of NRZ and large-RZ to short-RZ-OOK by means of a single commercial Quad SOA-MZI is demonstrated for grooming 85.4 Gb/s frame. The output RZ-OOK signal is suitable for further tributary multiplexing onto...
We report the first gridless networking field trial with flexible spectrum switching nodes over 620 km field fibre links. Successful transport, spectrum switching and defragmentation achieved for mixed line signals including 555G and coherent 100G.
