Huawei Unveils the World’s First 320T Centralized All-Optical Switching WDM Prototype at MWC 2016


[Barcelona, Spain, February 24, 2016] Huawei showcased the world’s first 320T centralized all-optical switching WDM prototype “OXC” at the Mobile World Congress (MWC) 2016. Each OXC has a 320T switching capacity, which is 12 to 16 times the capacity of traditional OTN devices. The power consumption of OXC optical switching just equals one thousandth that of traditional OTN switching. The OXC provides high capacity, low power consumption, and low latency for cloud era’s data center (DC) interconnection.


The explosive growth of cloud computing and services prompts carriers worldwide to focus on DC network transformation. The increase in the number of data center interconnection services is posing higher switching capacity requirements at supercore sites. However, existing devices at these sites cannot meet future switching capacity requirements of 100T and beyond.


The Huawei OXC provides centralized optical switching technologies with minimal installation footprint and low power consumption, and implements all-optical switching at significantly lower installation, operation, and maintenance costs, breaking through traditional switching barriers.


The OXC features industry-leading N x N centralized switching architecture, and provides 1+1 optical cross-connection protection capabilities and flexible, colorless, directionless, and contentionless switching for multidimensional and multiple wavelengths. For the first time ever, topology-independent all-optical switching has become a reality.


Rapid developments in the information industry promote the reconstruction of carriers’ backbone networks, with increasingly high requirements on capacity, traffic optimization, reliability, and O&M. Huawei Transport Network solutions are at the forefront of advances in the latest optical transmission technologies, meeting current and future requirements for carrier-class bearer networks and helping carriers overcome the challenges of Big Data floods.


MWC 2016 takes place in Barcelona, Spain from February 22 to 25. Huawei will showcase its latest products and solutions at Fira Gran Via Hall 1 and Hall 3. For more details, please visit:
