World’s leading fiber-based telecom service provider selects Nokia Siemens Networks for the 100G+ pan European network to handle future IP traffic growth

TeliaSonera International Carrier customers can now enjoy a significant increase in network capacity. The carrier has deployed a new overlay network across Europe to address the tremendous growth in data traffic. Nokia Siemens Networks has built this new network to deliver speeds of 100G and beyond. The existing optical network for the operator was also provided by the vendor.

“The increased adoption of bandwidth-hungry applications requires capacity upgrades,” said Mattias Fridström, vice president, head of technology, TeliaSonera International Carrier. “We share a long-standing relationship with Nokia Siemens Networks and are very satisfied with its installed base in 10G and 40G wavelengths across the European segment of our global network. Its leading technology for high capacity networks is exactly what we required for this major transition in our network.”

“TeliaSonera International Carrier is a market leader with its networks across North America, Europe and Russia. Maintaining that position requires greater network capacity to ensure the best end-user experience,” added Mikko Lavanti, head of optical networks customer sales and support at Nokia Siemens Networks. “The new overlay network with our latest technology is fully integrated with Juniper routers to offer a seamless service portfolio to TeliaSonera’s subscribers. It will initially have 40 and 100GE (gigabit Ethernet) capacity with the potential to be upgraded to 400G and beyond.”

Under this contract, Nokia Siemens Networks has deployed a new 100G DWDM (Dense Wave Division Multiplexing) network based on its hiT7300* platform that is operating with coherent CP-QPSK** technology. By offering DCM-free transmission, this solution enables lower latency and allows a rapid, cost effective transition to 100G line speeds. The CP-QPSK modulation format is also used for TeliaSonera’s existing network to improve performance. Nokia Siemens Networks also provides a full set of care services including software maintenance, help desk as well as spare part management services.

TeliaSonera was honored with “The Best Next Generation Global Optical Service Provider” award at the 14th WDM and Optical networking Conference in Monaco, June this year.
