Nortel, Telstra Complete World's Longest 100 Gbps Trials

Telstra, Australia's largest telecommunications carrier, has successfully completed the first 100 Gbps trial over a 2,038 km stretch of its existing fiber optic network using high-speed optical transport technology from Nortel.
The trial, conducted in July this year, also successfully tested 40 Gbps transport over 3,370 km of fiber between the Australian cities of Sydney and Adelaide. Nortel said both 40 Gbps and 100 Gbps trials are believed to be the longest unregenerated distances ever successfully attempted using the technologies, and demonstrate its 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.
"The success of the trial builds on Nortel's leading 40 Gbps 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 100 Gbps," said Anthony McLachlan, vice president, Carrier Networks, Nortel Asia. "During the trial, the Nortel 100 Gbps solution allowed Telstra to redefine the value of its extensive fiber infrastructure with a tenfold increase in capacity, compared to that of existing 10 Gbps networks, and made the Telstra infrastructure the fastest of its kind globally over anywhere near this distance."
"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," said Michael Rocca, managing director, Networks and Services Group, Telstra. "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 40 Gbps and 100 Gbps technology using their existing 10 Gbps network infrastructure.
"10 Gbps components are readily available, cost effective and field proven, and our technology allows carriers to extend their substantial investments in their 10 Gbps networks with a cost-effective upgrade to 40 Gbps and 100 Gbps," said McLachlan. "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."
