Abstract :
CapEx minimization for space division multiplexing (SDM) networks is studied by modeling and solving the CapEx-minimized planning problem. Physical layer constraints, including the mode-binding constraint in few-mode fiber (FMF) transmission system and the inter-core crosstalk constraint in multi-core fiber (MCF) transmission system are considered. Numerical results show that SDM networks has CapEx advantage compared with conventional single-core/mode WDM networks when specific switching structures and crosstalk suppression signal processing methods are used, while this benefit is sensitive to network traffic.
