Deutsche Telekom's TeraStream Shows Multivendor 100GbE / DWDM

Deutsche Telekom confirmed multi-vendor interoperability on a 100 Gigabit Ethernet long haul link on TeraStream pilot network in Croatia.

The tests, which were a joint effort between Alcatel-Lucent, Cisco Systems, Hrvatski Telekom and Deutsche Telekom, represent an important milestone towards the future of generally available 100GbE networking.

The actual link, the industry’s first of its kind, consisted of 600 km of Standard Single Mode Fiber (SMF) between the cities of Split and Varazdin using leveraging the TeraStream colorless, open spectrum, passive network. The 100 Gbps signal, carrying live production traffic, used ITU standard 50GHz spacing via a high gain forward error correction algorithm capable of achieving 10Gbps comparable distances. The implementation in this test used pre-standards, aligned in ITU Study Group 15.  Multi-vendor interoperability on the 100 Gigabit Ethernet (GbE) long-haul DWDM links was established between IP routers from Cisco Systems and Alcatel-Lucent. Cortina Systems also provided technology for the tests.

"The need for bandwidth is constantly growing. This milestone is another important step towards the future of generally available 100GbE networking. Leveraging the TeraStream passive network and the jointly developed standard, we can achieve drastic cost savings in the area of optical transport. We envision that this will also be the most cost efficient optical interconnect for datacenter applications. We are pleased with the latest advancements from the vendors," stated Bruno Jacobfeuerborn, Group Chief Technology Officer, Deutsche Telekom AG.

"In order for us as a company to achieve success in the future, we need to have networks that can support the most advanced communications and services,” said Ivica Mudrinić, President of the Management Board of Hrvatski Telekom. “I am especially proud of two things: Firstly, that Croatia with Hrvatski Telekom is the first country in the world to install this innovative technology which will become key to our future success, to the development and competitiveness of the economy and will improve the lives of individuals. I am also proud of our Croatian experts who, together with colleagues from Deutsche Telekom, are implementing this highly demanding, innovative network concept."

In December 2012, Deutsche Telekom AG together with Hrvatski Telekom (HT), Deutsche Telekom AG’s subsidiary in Croatia, launched its TeraStream pilot network in Croatia. TeraStream is an industry leading network concept, based on a cloud enabled IP architecture. The pilot features 100 Gbps links over a filter-less DWDM system.
