PIPE Pacific Cable, commonly known as PPC-1, is a submarine cable network recently constructed by PIPE International, a subsidiary of Australia’s PIPE Networks. The cable is approximately 6900 km long, and runs from Cromer, Australia, to Piti, Guam . It promises huge international backhaul cost savings to Australian customers, for access to the US internet backbone, quoting up to "50% savings" versus existing cable operators. A cable layer or cable ship is a deep-sea vessel designed and used to lay underwater cables for telecommunications, electricity, and such. Cable ships are distinguished by large cable sheaves for guiding cable over bow or stern or both. Bow sheaves, some very large, were characteristic of all cable ships. Newer ships are tending toward pure stern layers with stern sheaves only as seen in the photo of the Cable Innovator at the Port of Astoria on this page. The names of cable ships are often preceded by "C.S." as in CS Long Lines. The first transatlantic telegraph cable was laid by cable layers from 1857–1858. It briefly enabled telecommunication between Europe and North America before misuse resulted in failure of the line. In 1866 the Great Eastern successfully laid two transatlantic cables, securing future communication between the continents. HMTS Monarch (renamed CS Sentinel 13 October 1970) completed the first transatlantic telephone cable, TAT-1 in 1956 from Scotland to Nova Scotia for Britain’s General Post Office (GPO).
