An independent operator of trans-⁠Pacific capacity

Trans Pacific Networks is based in the Cayman Islands. We conceived the route that became Echo. We own three of its twelve fibre pairs end to end. On Tabua, we own a full fibre pair.

Route diversity by design

New paths that avoid the South China Sea and the crowded northern corridors.

Ownership, not resale

Fibre pairs held end to end, sold as spectrum, wavelengths, scalable capacity and long-term IRUs.
