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

Networks can be more efficient than they are today, by utilizing spare network system margin

Flexible & Programmable photonics can create extra capacity where needed

Advanced control, modelling, fabrics and management can convert the capacity to Revenue
