Impact of Photonic Integration on Optical Services Serge Melle VP Technical Marketing, Infinera
Internet Backbone Growth • Industry consensus indicates a sustainable growth rate of 75% to 100% per year in aggregate traffic demand • Traffic increased more than 10,000x from 1990 to 2000 • Traffic projected to increase an additional 1,000x from 2000 to 2010 [1] K. G. Coffman and A. M. Odlyzko, ‘Growth of the Internet’, Optical Fiber Telecommunications IV B: Systems and Impairments, I. P. Kaminow and T. Li, eds. Academic Press, 2002, pp. 17-56.
The Future Belongs to Tb/s Links • Carriers deployed Nx10 Gb/s networks several years ago • Now evaluating deployment of (Nx) 40 Gb/s router networks • Current Backbone growth rates, if sustained, will require IP link capacity to scale to > 1 Tb/s by 2010
Scalability Challenges • Service scaling: • Evolution to 40G and 100GbE services • Network scaling: • >1Tb/s per fiber • Nodal scaling • System size for >Tb/s nodes • Operations • Deployment, fibers, spares,

100 Gb/s Transmit 100 Gb/s Receive Photonic Integrated Circuit Innovation 100Gb/s Transmit 100Gb/s Receive 5mm • DIRECT BENEFITS: • Reduce size, power, cost and improve reliability over discrete optics • STRATEGIC BENEFITS: • Affordable OEO conversion re-enables digital reconfigurability at every node • Order-of-magnitude in capacity deployment & scalability • Result: Lower CapEx, lower OpEx, more flexible reconfigurable optical network
Conventional WDM: Capacity deployed one lambda at a time OEO only at network edge Network service tied to the wavelength Managing bandwidth occurs elsewhere PIC-based WDM: Capacity deployed 100G at a time OEO at all service locations De-couple service layer from the transport layer Integrate DWDM with digital service switching Impact of PIC Technology Line Trib Transponder Line Trib
How PIC Capacity Is Managed Scalability 10-l x 10G • 100G PIC = 10 x 10G lambdas = 40 x ODU1 • Sub-wavelength bandwidth management maximizes service delivery flexibility • Super-wavelength bandwidth management supports 40G and 100G services Flexibility 4 x ODU1 per 10G
PIC Capacity Scalability Scalability 20-l x 20G • Increase PIC scalability through: • More channels (ie: from 10 to 20 lambda or more) • Higher bit rates (ie: from 10Gb/s to 20Gb/s to 40Gb/s) • Also increasing WDM line capacity to >1Tb/s per fiber Flexibility

Outage may last minutes or hours. If spare bandwidth is available, GMPLS reroutes, providing a “quick fix” at no additional cost. GMPLS-based transport system
