Key Facts:

• Founded in 2016, TPN is delivering a new, direct, non-stop route from Southeast Asia to the U.S., with the Echo cable system as its flagship. TPN is adding additional systems across the Pacific, including the Tabua cable, to form one cohesive network.
• The Echo subsea cable system spans 16,051 kilometers and is the first cable to directly connect the U.S. to Singapore with direct fiber pairs over an express route. It offers lower latency for users accessing applications running on the Google Cloud Platform (GCP) in those regions, home to some of the world’s most vibrant financial and technology centers.
• Tabua is a new transpacific subsea cable connecting the U.S. to Australia and Fiji. Part of Google’s South Pacific Connect initiative, Tabua consists of 16 fiber pairs on its trunk and branching segments. Each fiber pair is designed with a minimum capacity of approximately 17 Tb/s using current technology, for a total system capacity of 272 Tb/s.
• With Ciena’s GeoMesh Extreme solution, which includes the Waveserver compact interconnect platform powered by WaveLogic 6 Extreme (WL6e) as well as the 6500 Reconfigurable Line System (RLS), TPN is building a reliable network between Southeast Asia and the U.S. Ciena’s open architecture approach also supports spectrum sharing and fluid scalability, enabling TPN to seamlessly expand its network to address continued growth in bandwidth demand. Ciena’s professional services team will provide installation and support.
