We propose a cost-effective and scalable OXC/ROADM that consists of a subsystem-modular express switch part and a transponder-bank-based add/drop part. The effectiveness of the proposed architecture is verified via a hardware scale evaluation, network performance simulations, and transmission experiments. The architecture enables large throughput and offers significant hardware-scale reductions with marginal fiber-utilization penalty against the conventional architectures. A part of the OXC/ROADM designed to accommodate 35x35 express fiber ports and 2,800 transponders for add/drop is constructed. Its net throughput reaches 314 Tbps using 80 channels of 120-Gbps signal (30-Gbaud dual-polarization quadrature phase-shift-keying signals with 7% overhead are assumed).
