Abstract
In resource allocation in space-division multiplexing elastic optical networks with multi-core fibers (MCFs), indirect inter-core crosstalk (IC-XT) has been ignored because of being negligible. However, in very dense MCFs, there is a potential concern that the indirect XT may become non-negligible. We propose a new IC-XT evaluation method considering the indirect IC-XT. Simulation results demonstrate that the performance of the conventional core prioritization scheme can be negatively affected by the indirect IC-XT in some cases. Furthermore, we indicate the conditions under which the indirect IC-XT is negligible.
