First Demonstration of Subsystem-Modular Optical Crossconnect Using Single-Module 6×6 WSS

We demonstrate a highly scalable subsystem-modular OXC, where a newly developed single-module 6×6 WSS is utilized as a sub-OXC. Network simulations in dynamic-traffic scenarios assure its good applicability. Its technical feasibility is confirmed by transmission experiments using 32-Gbaud DP-QPSK signals.
