The Japan-Washington State Trans-Pacific Cable System (JAWS TPCS) is a new transpacific submarine cable system planned to provide a diverse and low-latency connection between the United States and Japan, as well as onward connectivity to Asia-Pacific destinations.

The JAWS cable system is planned by Quintillion, an Alaskan telecommunication company.

Quintillion has established a fiber-optic cable network that extends 1,200 miles under the sea and 500 miles over land in Alaska, as the Phase 1 project of the legacy Arctic Fibre which was acquired by Quintillion in May 2016.  Quintillion's fiber network is now the first and only system in Alaska with world-class infrastructure that delivers sub-gigabit, gigabit, and terabit bandwidth services to the North American Arctic.

The JAWS cable system is the Phase 2 project of Quintillion network. It will enable interconnection with the existing Alaskan network. All of which will be achieved using a new submarine cable system, extending from a new branching unit (to be placed along the JAWS-TPCS to the Phase 1 Nome branching unit).

The JAWS cable system will features:

• Being a replacement for the PC1 cable which will reach its end of life in about five years.
• Diverse cable landing site in Washington State to improve diversity by adding to existing ones in Oregon and California.
• Direct access to Seattle and Portland.
• Cable landing site in Ajiguara (Japan) to provide multiple cross-connection options in Asia.
• A cost-effective backhaul to Tokyo.
