Carriers and Equipment Suppliers Need to continue to differentiate themselves • Increasing capacity on Submarine routes, using latest technology (40/100G
Coherent, softFEC, even used on routes designed for 2.5 G ) • But…Price per bit needs to continue to decline as well as power per bit
• Faster Lead times
• Lowest possible latency
• Carriers need to deliver a flexible set of services (all 10G permutations, 40GbE,
100GbE) faster than their competition • Drive towards Operational Simplicity
• Faster, cheaper, turn-up, provisioning, restoration • Simplified troubleshooting and sparing
Trend towards Bandwidth Commoditization on Major Submarine Routes

Bandwidth Virtualization
Rapid Provisioning of End to End Global Services
Waves are resources, used by services Service layer need not consider or even be aware of optical
parameters Different services simply consume bandwidth – independent of
wavelength bit rate & link engineering
