FLAG x Ciena Partnership

Redefining Global Connectivity

FLAG and Ciena are powering the world’s most strategic subsea corridors.
From the US West Coast to Asia, Europe, the Middle East and beyond with next-generation technology.

One of the world’s largest privately owned subsea cable networks; over 100,000km across the US, Europe, Middle East, India & Asia, with extensions to 200+ countries.
Ciena’s latest technology, WaveLogic 6 ©, delivers best spectral efficiency with 50% less power per bit, purpose-built for the AI era.

The Infrastructure the AI Era Demands

Our network covers major global routes, providing seamless connectivity to key locations across continents. Through strategic partnerships and alternative routing options, we ensure route resiliency and access to major cities worldwide, delivering connectivity wherever you need it.

Two Global Leaders, One Vision

“To build a fully connected, fully resilient global fibre link across the globe from the US to Singapore, onwards to Mumbai and into Europe, capable of carrying the exponential demands of AI, cloud and human progress, sustainably and at scale.”

Pillars of the Partnership

FLAG’s Vision 2030 strategy centres on completing a privately owned subsea cable network with fibre links to all major regions around the globe: the US, Europe, the Middle East, India and Asia. ECHO, ready in mid-2026, completes the trans-Pacific link, uniting FLAG’s existing network with a direct Singapore-to-California route. The goal: one neutral, end-to-end global provider with no shared infrastructure constraints, giving customers the resilience and diversity the AI era demands.

Ciena’s Wave Logic 6 Extreme delivers a 50% reduction in space and power per bit versus the previous generation, enabling FLAG to upgrade existing cables rather than always laying new ones. Exponentially more capacity, with a dramatically smaller environmental footprint. Under Vision 2030, FLAG is actively extending the lifespan of its existing subsea cables through advanced coherent optical technology, proactive monitoring and intelligent data analysis, not just building new routes, but making the most of every metre of fibre already in the ocean.

Global AI workloads don’t just need massive bandwidth, they also need determinism in low latency and performance with an ability to scale on demand across continents and low latency predictability, ultra-low latency and the ability to scale on demand across continents. Together FLAG’s global subsea network and Ciena’s adaptive networking platform delivers exactly that: infrastructure that can satisfy unpredictable bandwidth demand when needed. From 400GE today, and ready to provide 800GE on the most important Subsea cables in our network, this partnership is engineered to stay ahead of the curve, not catch up to it.
