The single-channel 2.4-Tbps transmission took place on MTN’s national fiber-optic network backbone. The parties actually tested two multi-terabit transmission approaches. They achieved the 2.4 Tbps via 16-QAM over a reach that exceeded 300 km. They also transmitted 2 Tbps using QPSK over 1,031 km.
Meanwhile, they also tested Huawei’s transport SDN features. Huawei says its transport SDN approach used physical network modeling and resource abstraction to achieve transmission pipe virtualization. The trial successfully demonstrated SDN features such as bandwidth on demand (BoD), virtual transport service (VTS), and automatic O&M functions, Huawei says.
"With this successful field trial, we have demonstrated our commitment to digital innovation," commented Navi Naidoo, group technology officer at MTN. "MTN continues to invest in future-proof transport networks to realize world class technologies, not only to our existing markets, but to extend our technology offerings globally. We believe that networks such as cloud computing, streaming media, and mobile broadband must be scalable, intelligent, and flexible. To this end, Huawei's next-generation optical evolution concept 'SDN-based flex optical network' properly fits our requirements."
"Huawei will maintain cooperation and joint innovation with MTN, and continue to promote the commercialization process of SDN and ultra-high speed optical transmission technology, in order to jointly meet the challenges of a digital future," added Zha Jun, president of Huawei's Fixed Network Business Unit.
