The challenges of migrating optical networks to 400G

While 400G is the answer to increasing data demands, there will be an initial struggle on the network backbone in supporting these initiatives and fulfilling the promise of higher-capacity transport. 400G is not a natural extension to existing network infrastructure, and requires taking into account new restrictions and a redesign of the optical network infrastructure. 400G capacity over a single wavelength with its high baud rate is simply too spectrally wide to pass through the 50-GHz filters and fixed grid ROADMs (reconfigurable optical add-drop multiplexers). A new “runway” is required to reap the benefits of this new technology.
