ECI Telecom transmits coherent 100G over 4600 km of submarine cable

Optical transport equipment vendor ECI Telecom reveals that its Apollo OMLT packet-optical transport platform successfully transmitted 100-Gbps coherent traffic between Tel Aviv and Bari, Italy, a round-trip distance of 4600 km. The coherent transmission, part of a trial executed in conjunction with the Tera Santa Consortium, used Bezeq International’s Jonah submarine fiber cable network.

The Tera Santa Consortium, with financial support from the Israeli Office of the Chief Scientist (OCS) through its Magnet program, aims to develop the world’s first terabit orthogonal frequency-division multiplexing (OFDM) based fiber-optic network. The trial was part of the consortium’s research into long-distance adaptive coherent channel behavior. It also demonstrated the robustness of the soft-decision forward error correction (SD-FEC) technology the Apollo OMLT employs, ECI asserts.

“ECI once again demonstrated the powerful performance of our innovative coherent technology with SD-FEC algorithms by transmitting 100G link over Bezeq International's submarine cable for 4,600 km with no regeneration,” says Eran Dariel, general manager, portfolio business, at ECI Telecom. “The 100G channels from the Apollo OMLT allow submarine cable operators to increase significantly the network capacity over expensive links with minimal network adjustment. ECI already deployed and trialed 100G solutions in various customer networks and now we also displayed our capability over submarine cables.”

ECI is a founding member of the Tera Santa Consortium. Other members include Finisar Corp.’s Israeli subsidiary, Orckit-Corrigent, MultiPhy, Optiway, Civcom, Bezeq International, the Technion Israel Institute of Technology, Ben-Gurion University, the Hebrew University in Jerusalem, Bar-Ilan University, and Tel-Aviv University.
