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


Line-side N x 100G DWDM and soon migrating to Terabit SuperChannels

Photonic Integrated Circuit (PIC) based 100G

Coherent detection (huge tolerance to CD and PMD, improved fiber plant designs possible

Flexcoherent: Multiple modulation schemes, wave by wave, same line card software programmable

Advanced SD FEC and Coherent Algorithms

All-encompassing flexible OTN / ASON/GMPLS / Packet architecture

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
