EXAMPLE USE CASES – CONVERTING SPECTRUM MARGIN TO REVENUE
Rapid Deployment of new services
Fault Recovery capability
Temporary High Bandwidth Demands
• New Revenue streams – e.g. On-Demand services tiers (e.g Data Centre)
• Simpler forecasting/ reduced spares• Respond instantly to new capacity
• Enhance network resiliency by allow the control-layer to utilize Net System Margin Analytics in the event of a fault
• Accommodate demand for short-term bandwidth without having to purchase new hardware
• Addressing spiky demand; Events, large DB backups, new DC synchronization/turn-up, etc.…

ADDRESSING INEFFICIENCIES IN OPTICAL NETWORK OPERATIONS
Use planning tool to validate all network paths for expected traffic flows
Network is planned assuming full-fill, end-of-life conditions; all margin is reserved day 1
Transponders used at fixed capacity/ wavelength; based on end-of-life conditions
PRESENT MODE OF OPERATION (PMO)
FUTURE MODE OF OPERATION (FMO)
= 100G
Retrieve link margin
Set flexible transceivers to maximize capacity for specific link and available margin
