Demonstration of Any-Care-Access Non-Directional Spatial Cross-Connects Based on Core Selective Switch with and without Core-Contention Constraint

We demonstrate any-core-access (AC) and non-directional (ND) spatial cross-connects (SXCs) employing a core selective switch and core selector for spatial channel networks. In addition to AC and ND characteristics, a core-contention-less feature is achieved by introducing a newly developed core/port selector into the SXC design.
