A1 Telekom Austria deploys 100G DWDM from Coriant

Optical supplier Coriant says that A1, the Austrian subsidiary of Telekom Austria Group, has deployed Coriant’s hiT 7300 intelligent optical transport platform to increase the capacity of its fiber-optic network infrastructure and enhance the performance of its converged fixed line and mobile service offerings. The hiT 7300 is the flagship platform of the former Nokia Siemens Networks (see “Coriant unleashed as Marlin Equity Partners closes acquisition”).

Optical supplier Coriant says that A1, the Austrian subsidiary of Telekom Austria Group, has deployed Coriant’s hiT 7300 intelligent optical transport platform to increase the capacity of its fiber-optic network infrastructure and enhance the performance of its converged fixed line and mobile service offerings. The hiT 7300 is the flagship platform of the former Nokia Siemens Networks (see “Coriant unleashed as Marlin Equity Partners closes acquisition”).

A1’s nationwide DWDM backbone network, which recently began commercial operations, provides the resilient foundation for enhanced end-user services by enabling A1 to rapidly deploy service capacity and seamlessly scale to connection speeds of 100 Gbps and beyond as consumer and business demands for network bandwidth evolve. A1’s new network connects Vienna with all major cities in Austria and is designed to support the increasing use of high-bandwidth enterprise and subscriber services and applications, including on-demand high-definition (HD) video streaming, 4G/LTE, broadband access, IPTV, and cloud computing.

“We continue to advance the capabilities of our network infrastructure to ensure the delivery of best-in-class converged services and the highest quality broadband experience for our customers,” says Marcus Grausam, A1’s chief technical officer. “We selected Coriant not only for the superior performance of its coherent optical transport system, but also for the embedded system intelligence that allows us to simplify operations, speed the provisioning of network capacity, and adapt to the dynamic, real time needs of today’s end-user applications.”

The state of the art photonic mesh network is based on Coriant’s industry-leading hiT 7300 DWDM transport system, which allows A1 to support transmission speeds of 40 Gbps and 100 Gbps, maximize utilization of its fiber infrastructure, and reduce overall latency to ensure the highest service performance.

Based on coherent transmission, the hiT 7300 supports the efficient transmission of 40 Gbps and 100 Gbps per wavelength while providing a pragmatic path to higher transmission capacities with advanced capabilities such as increased spectral efficiencies using FlexiGrid technology.

The hiT 7300’s implementation of colorless, directionless, and contentionless reconfigurable add-drop multiplexer (CDC-ROADM) technology delivers the maximum level of flexibility and adaptability, the company claims. Complementing this optical layer flexibility is Coriant’s TNMS management system, which allows A1 to centrally manage optical service connections and automate traditionally manual tasks, thereby reducing provisioning times from days to minutes.

With advanced coherent detection capabilities, the hiT 7300 eliminates the need for dispersion-compensating fibers in the network and delivers the low latency performance required for real time applications like telemedicine, financial trading, and online gaming.
