One of the main benefits of Open ROADM is that it provides a standard management interface and a standard interop mode for optical modules that can be implemented by modules from different vendors.
This allows network operators to choose the best module for their needs without being locked into a specific vendor’s ecosystem.
Commercially available CFP2 and QSFP-DD pluggable modules support the Open ROADM standard interface and can be used in both Xponders and routers for IP-over-DWDM.
