The Telstra Endeavour submarine cable system is a linear single span system between Sydney and Hawaii. The Telstra Endeavour submarine cable system provides an improvement in latency over existing submarine cable systems, with 90ms (Sydney-Hawaii) and 138ms (Sydney-Los Angeles via Endeavour and AAG), it is now the shortest path from Australia to the USAs. The Telstra Endeavou offers an alternative trans-pacific route, improving flexibility and reliability of the submarine networks.
