Massive bandwidth growth driven by the cloud is changing subsea transport networks and investments. Cloud scale connectivity demands openness in software and networking, virtually infinite resources, and instant scalability. This has led to a new generation of multi-terabit photonic technology and platforms that are smaller, more spectrally efficient, and more intelligent laying the foundation for cognitive networking. New technology capabilities provide on-demand software defined capacity (SDC), automated optical engineering and a pay-after-you-deploy model, all supported via a rich set of SDN controls and unique hardware innovations. This presentation will discuss the new and simplified cloud scale transport network enabling subsea operators to deploy new and differentiated service offerings for their customers.
