The PPC-1 (PIPE Pacific Cable 1) submarine cable system consists of two segments of digital fiber-optic cable: (1) the Australia-Guam Trunk, connecting Sydney, Australia with Piti, Guam; and (2) the PNG Spur, connecting Madang, Papua New Guinea with a branching unit located on the Australia-Guam Trunk. The Australia-Guam Trunk of the PPC-1 cable system consists of two optical fiber pairs, with a design capacity of 96 wavelengths (10 Gbps) on each fiber pair, for a total design capacity of 1.92 Tbps. The initial configuration of the Australia-Guam Trunk provides a total of 140 Gbps of capacity. The initial configuration of the PNG Spur provides a total of 20 Gbps of capacity, 10 Gbps on the Papua New Guinea-Guam route and 10 Gbps on the Papua New Guinea-Australia route.

The PPC-1 cable project was lunched on January 14, 2008. On September 22, 2009, Internode released a press release claiming successful transmission of IP packets across the PPC-1 cable, making it the first commercial entity to make use of the PPC-1 cable. The PPC-1 cable project was formally completed on October 8, 2009.
