ROADM
☺ Increase performance – 4 x increase for existing 10G DWDM system
☺ Easy to upgrade / maintain – Zero touch provisioning
☺ Enhanced resiliency – Proactive protection
☺ Low power consumption due to less components / active devices

WDM cloud
�CTC (Cisco Transport Controller) shows CRS nodes with WDM i/fs as well as MSTP nodes
�CTC can set up A-Z connections (incl. DWDM controller)
�CTC displays “show DWDM controller” results and alarms
With Cisco IPoDWDM:
�Additional switching added to Cisco ONS15454 MSTP to allow full automation of add drop switching
�Colorless port
�Omni-directional ROADM
�Only once this is deployed does automatic lightpath setup make sense

Incumbent ROADM + OXCSolution:
� Mesh switching is deployed in a limited way, and only takes care of pass-through wavelengths
� Need to manually reconnect if direction or color changes
