800Gbps/λ WDM Metro-Access Network by Novel Photonic Integrated EDWA and SOA-Based WSS Nodes

We demonstrate the first high-capacity 800 Gbps single-channel WDM metro-access network using photonic-integrated EDWA and $1 \times 4$ SOA-based WSS nodes. Results confirm dynamic add/drop switch over multiple nodes with 2.5 dB OSNR penalty and 10dB OSNR margin.
