Dell’Oro Group’s Advanced Research Report on DCI with IPoDWDM & WDM Systems monitors the Data Center Interconnect (DCI) market and key optical transport technologies such as IPoDWDM systems, ZR/ZR+ optical pluggable modules, and Disaggregated WDM systems, all designed for cloud providers. The report features quarterly tables and five-year forecasts for these segments, showing vendor market share by revenue and port shipments.
Optical transport technology for DCI is advancing through the development of ZR/ZR+ optical pluggable modules, which facilitate IPoDWDM and further enhance the disaggregation of the WDM network layer.
The research examines the major subsystems required for data center connections across metro and long-distance routes, utilizing coherent WDM technology for transponders and optical line systems (OLS). It also examines the use of pluggable ZR/ZR+ coherent modules in routers and Ethernet switches, an architecture often called IP-over-DWDM or IPoDWDM.
The research examines the disaggregation of the major sub-systems required for long-distance WDM transmission, including transponders and optical line systems (OLS), as well as the separation of WDM optics through pluggable ZR/ZR+ coherent modules. Because of their small size and low heat dissipation, ZR/ZR+ optics can extend DWDM transmission directly into routers and Ethernet switches—an architecture commonly referred to as IP-over-DWDM or IPoDWDM.
Disaggregation is reshaping how cloud providers and communication service providers build optical networks, offering greater flexibility in selecting network components and reducing vendor lock-in. Understanding the adoption of IPoDWDM and ZR/ZR+ optics helps industry participants assess market opportunities, technology transitions, and evolving vendor positioning.
