The technology demonstrated in this demonstration simplifies network configuration in distributed data centers, enabling high-speed data transfer while reducing power consumption and operational costs. This achievement allows distant data centers to be used as a single data center, achieving flexible data center utilization. 800G-ZR is attracting attention as an efficient network connection
