ECI Telecom, Finisar, MultiPhy, and the Technion Israel Institute of Technology have successfully demonstrated 1Tb/s transceiver transmission with the Tera Santa Consortium.
In the trial, the consortium transported non-regenerated 1Tb/s coherent super channel signal through the German Research Network - Deutsches Forschungsnetz e.V. (DFN-Verein) optical network. The trial, which took place at the Technische Universität Dresden, ran over DFN’s live X-WiN network, and used the 1Tb/s transceiver developed by the Tera Santa Consortium, as part of its research on 1Tb/s adaptive coherent channel behavior. It demonstrates the advanced capabilities of the Tera Santa 1T transmission system and technologies in compensating for channel impairments and chromatic dispersion utilizing advanced QAM16 and OFDM modulations and algorithms.
The Tera Santa Consortium was established in 2011 as an initiative of the Israeli Chief Scientist Office in the Ministry of Economy, through the Magnet Program which promotes cutting-edge technologies for the future. The Tera Santa Consortium brought together Israeli technology companies and universities to develop the world’s first Orthogonal Frequency Division Multiplexing (OFDM)-based optical transceiver. The members of the consortium are ECI Telecom, Finisar Corporation, MultiPhy, Cello, Civcom, Bezeq International, the Technion Israel Institute of Technology, Ben-Gurion University, the Hebrew University in Jerusalem, Bar-Ilan University and Tel-Aviv University.
For the trial, ECI deployed its Apollo family of packet-optical transport solution across DFN’s X-WiN’s network in 2012, and has since upgraded it to support the delivery of 100G services
Finisar demonstrated the software-defined 1 Terabit optical transceiver, which hosted the different algorithms developed by the consortium, in an end-to-end transceiver platform utilizing Finisar Flexgrid™ - WSS used to add/drop the 200GHz super channel signal. The OFDM algorithms were developed by both MultiPhy (128 OFDM carriers) and the Technion (1024 OFDM carriers), using two different implementation approaches.
"ECI and our technology partners Finisar, MultiPhy and the Technion, members of the Tera-Santa consortium, demonstrated the power of 1-terabit optical link coherent technology. With such high transmission rates, DFN can exponentially increase its network capacity and provide its users better and more cost effective services," stated Shai Stein, CTO, ECI Telecom and Consortium Chairman.
