Dr. Oscar Gonzalez de Dios of Telefonica introduced the deployment progress of IP over DWDM in the speech of OFC conference. Although this technology has been commercialized for more than 10 years, it has not been widely adopted in telecommunications networks. This approach works well for point-to-point links and DCI networks, but telecom networks have a long list of concerns about it. The introduction of the 400ZR/ZR+ module has shortened this list, but there are still two key issues to be resolved: Complexity: IP and DWDM transmission require different management teams and software systems; Speed: In terms of the data rate of the optical interface, the optical transmission is always ahead of the IP router. Dr. Oscar Gonzalez de Dios introduced Telefónica‘s progress in the unified control of IP r...
