Assigning Counter-Propagating Cores in Multi-Core Fiber Optical Networks to Suppress Inter-Core Crosstalk and Inefficiency due to Bi-directional Traffic Asymmetry

We propose the assignment of Multi-Core Fiber (MCF) cores in a counter-propagating way to design an MCF optical network, which suppresses MCF inter-core crosstalk and reduces the capacity inefficiency caused by increasing asymmetry of bi-directional traffic. Simulation results demonstrate the effectiveness of our proposed approaches.
