TPG Telecom and Infinera (NASDAQ: INFN) announced a major technology upgrade of PPC-1 submarine cable connecting Australia and Guam to significantly boost cable capacity from 8 Tbps currently to 12 Tbps, and improve reliability leveraging Infinera’s ICE6 800G solution.

PPC-1 is TPG Telecom’s ultra-long-haul cable system connecting Australia and Guam, including connectivity to Papua New Guinea. It has two fiber pairs spanning approximately 7,000 kilometers, with 78 repeaters spaced approximately 92 kilometers apart. The PPC-1 submarine cable is a major gateway for North America and other Asia Pacific destinations.

Using the latest technology from Infinera, the project will boost data capacity on this key internet backbone link by 50 percent, from 8 Tbps currently to 12 Tbps. Enabling direct connectivity to key Sydney points of presence (POPs) is part of this upgrade, delivering seamless connections for TPG Telecom customers beyond the landing station.


TPG Telecom has received the necessary regulatory approvals to modify relevant PPC-1 assets. The upgrade works are expected to be completed within 2021.
