TeliaSonera International Carrier taps Nokia Siemens Networks for 100-Gbps technology

TeliaSonera International Carrier customers has deployed a pan-European overlay network capable of supporting speeds of 100 Gbps and more using technology from Nokia Siemens Networks, the systems house reveals.

The network, which already used equipment from Nokia Siemens Network, now has 100G capabilities via the hiT 7300 platform’s CP-QPSK technology. CP-QPSK is a version of dual-polarization quadrature phase shift-keying (DP-QPSK) with coherent detection that Nokia Siemens Networks has used for both 40 and 100 Gbps (see "Nokia Siemens Networks delivers platform for rapid, cost-effective optical migration to 40G"). CoreOptics developed the technology before its acquisition by Cisco (see "The emerging role of electronics in optical networks").

“The increased adoption of bandwidth-hungry applications requires capacity upgrades,” said Mattias Fridström, vice president, head of technology, at TeliaSonera International Carrier. “We share a longstanding 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 100GbE [Gigabit Ethernet] capacity with the potential to be upgraded to 400G and beyond.”

Nokia Siemens Networks also will provide a suite of services including software maintenance, help desk, and spare part management.
