Trans Pacific Networks (TPN) has selected Ciena optical technology to increase capacity and efficiency across the Echo and Tabua submarine cable systems, strengthening digital connectivity between the United States and Southeast Asia. The deployment will enable terabit-class wavelengths on long-haul transpacific routes linking the U.S. with Indonesia, Singapore, Australia, and Fiji.
TPN operates fiber pairs on both systems, including Echo, the world’s longest subsea digital line segment at 16,051 km (9,975 miles). Using Ciena’s WaveLogic 6 Extreme coherent optics and Reconfigurable Line System, TPN aims to maximize fiber utilization while improving power and space efficiency on routes carrying growing volumes of cloud and AI-driven traffic. Pioneer Consulting is overseeing route engineering, quality assurance, and end-to-end project execution as TPN prepares for commercial service in 2026.
Echo provides a direct express route between the U.S. and Singapore, while Tabua forms part of Google’s South Pacific Connect initiative, extending connectivity to Australia and Fiji. Together, the systems create a cohesive Pacific network designed to deliver lower latency, higher capacity, and scalable expansion for carriers, hyperscalers, and enterprise customers.
- Trans Pacific Networks operates fiber pairs across Echo and Tabua as part of an integrated transpacific network.
- Echo cable spans 16,051 km (9,975 miles) and directly connects the U.S. to Singapore over an express route.
- Tabua cable consists of 16 fiber pairs with a total design capacity of 272 Tbps.
- Ciena supplies WaveLogic 6 Extreme–powered Waveserver platforms and the 6500 Reconfigurable Line System.
- Pioneer Consulting manages engineering, procurement support, and transition to operations.
“TPN is paving the way for a more connected digital experience for half-a-billion users across the U.S. and Pacific,” said Alfred Au Yeung, Chief Operating Officer at Trans Pacific Networks. “With Ciena’s innovative optical solutions and expertise in subsea cable architecture, we can boost capacity and continue to drive economic growth across the Indo-Pacific.”
🌐 Analysis
The Echo and Tabua upgrades reflect a broader subsea industry focus on extracting higher capacity from existing fiber pairs using next-generation coherent optics rather than deploying entirely new systems. Ciena’s WaveLogic 6 Extreme platform aligns with similar transoceanic upgrades as operators prepare subsea infrastructure for sustained growth in AI, cloud, and hyperscale traffic across the Pacific.
