Telia Sonera International Carrier (Stockholm: TLSN.ST) on Tuesday revealed its 100G optical plans, choosing Nokia Siemens Networks (NSN) as the underlying optical network element supplier.
For this deployment, the service provider is leveraging NSN's hiT7300 DWDM platform that leverages (coherent polarization multiplexed quadrature phase shift keying (CP-QPSK) modulation. This platform forms its Liquid Transport solution, one that also includes its TransNet DWDM planning tool.
A key point of this deployment is that it does not require Dispersion Compensation Modules, meaning it can reduce network latency and lower deployment costs. Besides equipment, NSN will provide the service provider with complementary software maintenance, help desk and network sparing management.
Like other large telcos, TeliaSonera International Carrier said what drove it deploy an overlay 100G pan European network is to "address the tremendous growth in data traffic."
Nokia Siemens Networks had also been the provider of the service provider's existing optical network, one where it offers 10G and 40G wavelengths across the European segment of its global network.
Following its contract with Italy's FASTWEB, the latest win with TeliaSonera International Carrier gives NSN another proof point for its 100G and overall optical program it can take to the 110 global DWDM customers that are perhaps considering similar transitions of their optical networks.
