The Palau Cable 1 (PC1) is the first international submarine cable connecting Palau, ready for service in 2017. The PC1 cable stretches about 200km connecting Palau to a branching unit of the SEA-US cable.

Palau's remote location led to a slow uptake of its information and communications technology (ICT) sector. Prior to the PC1, Palau relied on expensive and limited satellite links for internet connection.

Under the North Pacific Regional Connectivity Investment Project, Asian Development Bank (ADB) provides $25 million financing supports for the PC1 project, helping to build a submarine cable system linking Palau to the internet cable hub in Guam. 

The PC1 cable system is owned and operated by the Belau Submarine Cable Corporation (BSCC). Established in 2016, BSCC is a state-owned public corporation that owns and manages a submarine fiber optic cable network for the Republic of Palau. 

BSCC lands the cable at the Ngeremlengui Cable Landing Station, known as the Capacity Access Point at Ngeremlengui (CAP-N).

In addition to the PC1, BSCC builds the Palau Cable 2 as a branch to the Echo subsea cable with direct connections to Singapore and the mainland United States.
