Huawei Debuts Industry's First Hitless Adjustment of ODUflex (G.HAO) Prototype

Traditional Optical Transport Network outdoor units (OTN ODUs) provide a fixed amount of bandwidth for a certain service, regardless of the actual bandwidth requirements of that service, resulting in significant waste of an operator's already limited bandwidth. Huawei's new prototype revolutionizes current technology by flexibly configuring ODU size and bandwidth needs without affecting service.

Hitless Adjustment of ODUflex technology is a breakthrough for OTN network IP service and will be a milestone in OTN evolution, said Christian Chua, president of Transport Network Product Line, Huawei. As a major promoter of ODUflex standardization and advancement, Huawei is proud to pioneer the world's first Hitless Adjustment of ODUflex prototype that addresses a critical need for operators today – better managed bandwidth resources.

With ODUflex, a low-demand service no longer wastes excess bandwidth or occupies an entire ODU, instead, ODUflex enables the efficient scaling of bandwidth to actual bandwidth demand, thus freeing up bandwidth resources and dramatically boosting transport efficiency. In addition, Huawei's Hitless Adjustment of ODUflex prototype achieves efficient ODUflex transport, enhances the synergy between the IP and optical layers, and further improves the flexibility of Huawei's SingleBackbone solution. IP service transport routing is also flexibly optimized through the new interface, reducing the cost of building a backbone network.

According to Ovum, as of July 2010, Huawei ranks No.1 in the optical network and WDM/OTN markets. As the industry's leading transport vendor, Huawei is committed to providing operators around the world with premium solutions across WDM/OTN, MSTP and Hybrid MSTP, microwave series and end-to-end transport.
