Spatial division multiplexing enabled elastic optical networks (SDM-EONs) are the potential implementation form of future optical transport networks, because it can curve the physical limitation of achievable transmission capacity in single-mode fiber and single-core fiber. However, spectrum fragmentation issue becomes more serious in SDM-EONs compared with simple elastic optical networks (EONs) with...
A mode conversion-based crosstalk-aware routing, spectrum and mode assignment (MC-CA RSMA) algorithm is introduced in space-division multiplexing elastic optical networks (SDM-EONs) over few-mode fibers. Simulation results show the MC-CA RSMA algorithm can greatly reduce the impact of inter-mode crosstalk on network performance compared with benchmark algorithms.
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...
An auxiliary graph (AG) is designed to address traffic grooming under dynamic traffic scenario in spatial division multiplexing enabled elastic optical networks (SDM-EON). Various traffic grooming policies are achieved by adjusting the edge weights of AG, and evaluated through simulation in terms of spectrum efficiency and inter-core crosstalk. Numeric results show that the proposed SDM grooming reduces...
Space division multiplexing (SDM) over multi-core fiber (MCF) is advocated as a promising technology to overcome the capacity limit of the current single-core optical networks. Network survivability has become a more important concern to guarantee the QoS of more plentiful network traffics. In this paper, we have an investigation about dedicated path protection with considering inter-core crosstalk...
