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.
