SEA/US Underwater Cable

20 terabits per second is almost here.

We’re helping lead the way.

The Project

Hawaiian Telcom is a partner in the Southeast Asia-U.S. (SEA-US) Trans-Pacific Fiber Submarine Cable System, which will connect Indonesia, the Philippines, Guam, Hawai‘i and California by the end of 2016.

This cable system will provide an initial 20 terabit per second (Tbps) capacity, with state-of-the-art 100 Gigabit per second (Gbps) technology. As demand for capacity continues to grow and existing networks age, the SEA-US cable system is positioned to play a huge role in the future of bandwidth.

Extending more than 9,300 miles, the SEA-US cable system will follow a route that has been designed to bypass congested and earthquake-prone regions and ensure stable connectivity.


  • The fastest cable system connecting Southeast Asia and the U.S.
  • Connectivity with other existing and planned cable systems
  • Backed by expansive and redundant terrestrial networks connecting cable stations in Guam and Hawai‘i
  • Terminates in the “Telecom District” of downtown L.A.
  • A route that bypasses earthquake prone areas of East Asia (including Luzon Straight)

We’re proud to be a partner in this exciting project, which offers a very real solution to the exponential growth in demand for bandwidth.
