PPC-1 Cable Network Topology and Structure

The PPC-1 cable network is Australia’s first carrier neutral cable to offer POP to POP handover, overcoming the need for expensive backhaul to selected locations. Connecting Australia to Guam and providing onward connectivity to Asia and the United States, the PPC-1 cable network offers diversity to the few existing routes, and provides competitive pricing for greater capacity. The PPC-1 cable network has a design capacity of 1.92Tb/s run over 2 fibre pairs, operating with 96x10 Gbps DWDM technology.

The PPC-1 cable network is currently working with the Sydney-Guam Trunk and the PNG Spur which is a branch connecting Papua New Guinea, with three cable landing stations in Cromer, Madang and Piti.

The initial design of the PPC-1 cable network has considered the future requirement and upgrade of the PPC-1 system. Additional branches are reserved for connecting the cable to New Zealand, Brisbane and Port Moresby in Papua New Guinea in the future. And there is one dedicated fiber pair reserved for the connection between Australia and New Zealand.

The cable length of the Sydney-Guam Trunk is 6,900 Km, with approximately 70 ms of round trip delay (RTD) between Sydney and Guam.

Capacity on the PPC-1 cable network can reach the United States via onward connectivity with TGN-Pacific in the Piti cable landing station, or AAG, TPC-5 and CUCN via backhaul in Guam, which makes the shortest RTD between Sydney and west coast of the US approximately 180 ms.
