Huawei to supply OTN system for T-Mobile Austria’s network traffic growth

Huawei says it will supply telecommunications service provider T-Mobile Austria, a DT company, with its OTN system for a planned metro WDM and backbone WDM to support the provider's network traffic and services growth over the next five years. The projects are intended to build a next-generation large-capacity WDM transport network.

New services such as LTE/LTE-A, IoT, Big data, cloud computing, and 4K video increase traffic, and place demand on metro networks to provide higher bandwidth and lower latency. According to Huawei, T-Mobile Austria chose its OTN system to increase bandwidth to 200G per wavelength, with minimum optical fiber resources, using the latest WDM technologies to meet these demands.

T-Mobile Austria's current backbone network provides a maximum of 40 100G wavelengths, which cannot accommodate current and future traffic loads. According to Huawei, T-Mobile Austria also faces challenges from existing 10G/100G hybrid transmission in several places, affecting the network's transmission performance. T-Mobile Austria chose Huawei to address complex dispersion compensation configuration concerns in network planning, and O&M's inability to support the future DC-centric network architecture as well.

Huawei says it will provide an all-optical backbone network system to increase bandwidth, allow flexible traffic grooming, and support seamless evolution of the CloudDCI network architecture to prepare for future service cloudification challenges. Other benefits include:

• The network-wide CDCG-ROADM configuration supports on-demand service grooming, 80 100G/200G/400G channels per fiber, and seamless evolution to the future 1T ultra-high-speed transmission.
• The high-speed coherent communications technology meets bandwidth demands, and eliminates hybrid transmission and complex dispersion compensation configuration.
• The technology, together with Huawei's optical-layer OSNR monitoring, fiber self-test system and simplified OTN architecture, reduces complexity in network planning and O&M to meet inter-DC traffic growth over the next five to 10 years.

"As a long-term strategic partner, Huawei will continue to help T-Mobile Austria in the transformation to a digital service provider," said Duan Aiguo, general manager of WDM Domain for Huawei's transport network product line. “Huawei's simplified OTN solution will help T-Mobile Austria build a highly secure, large-capacity, low-latency, and easy-to-operate-and-maintain networks. The new network capabilities will enable T-Mobile Austria to enter more vertical industries. We are looking forward to the strategic cooperation between Huawei and T-Mobile Austria and will help T-Mobile Austria achieve greater business success and win-win development."

T-Mobile Austria serves 4.6 million users, and provides IT services around the world in cooperation with T-Systems, Huawei says. The provider currently deploys OTN devices at CO sites to simplify network layers, and eliminate intermediate aggregation and forwarding to achieve direct optical connections between sites, minimizing network latency.
