PLDT announced to activate the transpacific Jupiter cable system by July, 2022. The Jupiter cable system has landed in the cable landing station in Daet, Camarines Norte, linking the Philippines to Japan and the United States. It will tripple PLDT's international capacity to 60Tbps.

Jupiter cable system

The JUPITER Cable System is an open cable system, landing in Maruyama and Shima, JapanLos Angeles (Hermosa Beach) and Pacific City, USA; and Daet, the Philippines, for a total cable length of about 14,600km. it consists of 5 fiber pairs in the main trunk connecting Maruyama and Shima, Japan and Los Angeles. The Jupiter cable system was intitially designed with 400Gbps DWDM, for a total system capacity of 60Tbps, or 12Tbps per fiber pair. its main trunk has been ready for service as of May 2021.

The JUPITER consortium comprises Amazon, Meta (formerly Facebook), NTT, PCCW Global, PLDT and SoftBank.

PLDT owns one fiber pair (or 20%) in the main trunk, and two fiber pairs (100%) in its Philipines branch. PLDT's investment in the Jupiter cable system was reported be nearly P7 billion (US$136.7 million). 

The addition of the Jupiter cable system to PLDT’s infrastructure greatly boosts the telco’s extensive fiber network, providing greater capacity in multiple Terabits per second to customers as well as cable diversity to ensure ability to re-route traffic in the event of undersea cable cuts.

PLDT is currently the largest telecom operator in the Philippine. Jupiter is anticipated to increase PLDT’s international capacity of 20 Tbps to about 60 Tbps, an incremental of 40Tbps to US and Japan together.

Initially designed with 400Gbps DWDM technology and 12Tbps per fiber pair, the Jupiter cable system is capable of deliver 18Tbps to 20Tbps per fiber pair.



PLDT officially launched the Jupiter Cable System on July 29, 2022. PLDT has deployed 500Gbps DWDM on the Jupiter Cable System, to deliver capacity of 19.5Tbps on the Philippines-US route and 23.5Tbps on the Philippines-Japan route.
