Spatial division multiplexing elastic optical networks (SDM‐EONs) will become the most important form of future optical transport networks, because it can break the physical limit of achievable capacity in single‐mode and single‐core fibre. However, spectrum fragmentation issue becomes more serious in SDM‐EONs compared with in single EON. Crosstalk‐aware cross‐core virtual concatenation (CCVC) scheme is first proposed to solve the spectrum fragmentation issue in SDM‐EONs. Simulation results show that CCVC can achieve lower blocking probability and higher spectrum utilisation compared with single‐core virtual concatenation scheme.
