Demonstration of 4-Core/16-Core Fiber Heterogeneous Spatial Channel Network Comprising 19-Core Fiber Core Selective Switch-Based Spatial Gateway, 4-Core EDFAs, and 19-Core EDFAs

Inter-domain spatial-channel establishment and fault recovery are demonstrated over a 4-core fiber (CF) and 16-CF heterogeneous spatial channel network comprising a 19-CF core-selective-switch-based spatial gateway, fan-in/fan-out-less 4-C EDFAs, and cladding-pumped 19-C EDFAs.
