Power of “Smart Raman” Significant improvements over traditional deployment

•  Raman minimizes regens, increases reach

•  Smart Raman identifies high localized losses and reflections, avoiding connector & fiber plant damage

•  Start-of-life baseline for proactive monitoring and maintenance

Coping with the submarine capacity increase

•  Introducing ROADM capability at the landing station, allowing wavelength extension to the terminating PoP.

•  Introducing Gridless capability for the best use of available bandwidth

•  Increasing the CD compensation to 270,000ps/nm


Multi-Layer WAN Controller (MLWC) SDN Controller for Access, Metro and Core L3-L0 control

Multi-Layer Multi-Vendor Multi-Domain

• Single controller for L3, L2, L1, and L0 networks

• Hybrid operation for operation with existing distributed CP networks

• Service creation for all three layers via single API

• Support for multiple vendors via standardized interfaces

• Select support for specific vendors and platforms via existing non-standard interfaces

• Supports east/west and north/south APIs for hierarchical scale

• MLWC supports multi-level hierarchy as well as 3rd party orchestration systems
