Telstra, Australia’s largest telecommunications carrier, has successfully completed the first 100 gigabits per second (100G) trial over an unprecedented 2,038 kilometre stretch of its existing fibre optic network using innovative, high speed optical transport technology from Nortel.
The trial, conducted in July this year, also successfully tested 40 gigabits per second (40G) transport over 3,370 kilometres of fibre between the Australian cities of Sydney and Adelaide. Both 40G and 100G trials are believed to be the longest unregenerated distances ever successfully attempted using the technologies, and demonstrate Nortel’s capacity to deliver one of the most cost effective high speed broadband transport solutions available today.
The solution can position operators like Telstra to increase customer satisfaction through lower costs to the end user, and can provide the opportunity to deliver a wider range of managed applications and services.
Anthony McLachlan, vice president, Carrier Networks, Nortel Asia, commented: “The success of the trial builds on Nortel’s leading 40G technology and we are proud that Telstra has given us the opportunity to prove in a real network what others are only talking about regarding 100G. During the trial, the Nortel 100G solution allowed Telstra to redefine the value of its extensive fibre infrastructure with a tenfold increase in capacity, compared to that of existing 10G networks, and made the Telstra infrastructure the fastest of its kind globally over anywhere near this distance.”
Michael Rocca, managing director for the networks and services group at Telstra, added: “These trials with Nortel demonstrate that our existing network is capable of transporting even larger amounts of network traffic without incurring the cost of major equipment and infrastructure upgrades. Of course, they also contribute to the development of technology that will eventually benefit not only Australian consumers but also the worldwide telecommunications industry.”
The key behind the successful trials is Nortel’s dense wavelength division multiplexing (DWDM) technology, and specifically Nortel innovations such as advanced digital signal processing with coherent detection, and superior forward error correction (FEC). These technologies allow service providers like Telstra to migrate to 40G and 100G technology using their existing 10G network infrastructure.
Continued McLachlan: “10G components are readily available, cost effective and field proven, and our technology allows carriers to extend their substantial investments in their 10G networks with a cost effective upgrade to 40G and 100G. This opens up a new world of rich, interactive services such as high definition videoconferencing, managed storage and disaster recovery services, allowing carriers to generate new revenue from their networks and reduce their ongoing operating costs in the process.”
