Global submarine networking

Connecting the world with open submarine networks powered by revolutionary technology

The Internet. International communication. Global data transport. Without submarine networks, these wouldn’t exist as you know them today. Satellites only account for a small part of keeping the world connected. Submarine networks do the heavy lifting—from the ocean floor. It’s time we give this critical industry the recognition it deserves.

Subsea networks carry nearly 100% of the world’s Intercontinental electronic communications traffic. The submarine networking industry has experienced several technology changes in recent years, most importantly the adoption of coherent detection. This revolutionary technology changed how capacity was added to transoceanic corridors, extended the life of existing wet plant assets, opened existing wet plants to best-of-breed SLTE vendors, and completely changed legacy business

The Big 3

No. 1

Dynamic network provisioning enabling new service opportunities from on- demand bandwidth, circuits, and even dynamic spectrum

No. 2

Higher revenues and profits from submarine networks of any size or age, while leading the way toward software-defined, packet-switched submarine networks

No. 3

Maximization of submarine investment value by providing ultimate capacity and reach, maximum resilience, simple upgrading, and lower operating costs

What’s next

Following the technological revolution of coherent detection, the industry is undergoing yet another sea change in open cables. Open cables will have even greater impact than coherent detection, and the trans-Atlantic corridor already demonstrates initial evidence for this new trend.

Industry insights

Open submarine networks is truly is a revolutionary change coming to a conservative industry. From a technology perspective, open SDN-enabled submarine networks will completely change how they are modeled, designed, deployed, and managed. From a business perspective, network operators can choose best-of-breed technologies from a broader selection of vendors, streamline operational processes, accelerate service innovation, reduce time-to-market, and maintain pace with web-scale content players who increasingly account for the majority of transoceanic bandwidth growth.

Ciena Insights

There’s now a strong movement affecting all parts of the global network infrastructure, including most recently, the submarine network. It’s the “open” movement, which aims to remove the closed and proprietary nature from networks. Cable operators will be able to easily choose any vendor’s SLTE based on the best technology at the right cost points that addresses specific business requirements.

“There’s no ‘Plan B’ for interconnecting continents at the capacity and latency needed to keep the Internet humming—satellites need not apply. This important fact means that submarine technologies will continue to rapidly evolve, out of sheer necessity, just to maintain pace with our voracious appetite for Internet content.” – Brian Lavalee, Director of Portfolio Solutions Marketing for Ciena's packet and submarine networking solutions.
