The debate between IPoDWDM and IPoOT (optical transport) has existed for years. Which technology an operator chooses depends on many factors including application details and individual preferences. For example, an operator could choose to integrate DWDM transmission directly into IP routers, while another might decide to deploy optical transport. Many operators will combine multiple approaches. And now, the evolution of technologies for optical transmission at 400G and above, wavelength routing, and network control enables operators to customize integrated IP Optical solutions that optimize their networks for cost, performance and operational flexibility.

This White Paper discusses the merits of both approaches and how service providers can decide what is best for their individual networks
