Telefonica has selected Huawei for joint deployment of 100G intelligent metro network in Spain, helping Telefonica to modernize metro networks for richer and higher-quality broadband services and better user experience in the next 10 years. After the network reconstruction, Telefonica metro Optical Transport Network (OTN) will have a simplified and meshed architecture which enables one-hop transmission to ensure the lowest latency that provides an ideal foundation for 4K video services.
Huawei claims that its metro OTN solution uses the most advanced optical networking platform, providing auto-restoration features based on GMPLS control plane, which supports smooth evolution to Transport SDN (T-SDN). In addition, this solution provides 100G/200G bandwidth and supports evolution to 400G bandwidth, meeting the bandwidth requirements of the new 4K video and Telefonica Data Center Interconnect (DCI) services in the next 10 years, added Huawei.
