A future-proof optical transport network that addresses the surging demand for bandwidth-intensive applications has been unveiled by Nokia Siemens Networks. The company today announced that its Dense Wavelength Division Multiplexing (DWDM) platform will enable CSPs to seamlessly migrate existing 10 and 40 Gigabit per second (10G & 40G) optical networks to 400G with minimal investment. The hiT 7300 DWDM platform and TransNet for 400G optical transport networks will be available for delivery in the first quarter of 2011.
“Capacity demand in the backbone networks is increasing 60% per year,” said Bernd Schumacher, head of Optical Networks at Nokia Siemens Networks. “As networks move from 40G to 100G optical transport, 400G is the next evolutionary step. Nokia Siemens Networks is ready to support this transition by enabling CSPs to start deploying 400G optimized optical networks.”
The FlexiGrid technology* incorporated in Nokia Siemens Networks’ hiT 7300 DWDM platform** enables the migration to 400G networks by dynamically adapting the network’s wavelength grid to the needs of high-capacity channels. This is done using the network operator’s existing fiber infrastructure and without causing any disruption in service. In addition, Nokia Siemens Networks’ TransNet network planning tool allows service providers to plan and simulate the entire optical transport network to optimize the rollout while efficiently managing their network with the NetAct network management system. With these products, Nokia Siemens Networks not only ensures cost savings for operators but also improves their efficiency.
