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, 000 x from 1990 to 2000 Traffic projected to increase an additional 1, 000 x 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 Nx 10 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 Infinera Confidential and Proprietary | 3
Scalability Challenges § Service scaling: § Evolution to 40 G and 100 Gb. E services § Network scaling: § >1 Tb/s per fiber § Nodal scaling § System size for >Tb/s nodes § Operations § Deployment, fibers, spares, Infinera Confidential and Proprietary | 4

Photonic Integrated Circuit Innovation 100 Gb/s Transmit 100 Gb/s Receive 5 mm § DIRECT BENEFITS: 100 Gb/s Receive § 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 Cap. Ex, lower Op. Ex, more flexible reconfigurable optical network Infinera Confidential and Proprietary | 6
Impact of PIC Technology Conventional WDM: PIC-based WDM: § Capacity deployed one lambda at § Capacity deployed 100 G at a § § § a time OEO only at network edge Network service tied to the wavelength Managing bandwidth occurs elsewhere § time OEO at all service locations De-couple service layer from the transport layer Integrate DWDM with digital service switching Line Transponder Trib Line Trib Infinera Confidential and Proprietary | 7
How PIC Capacity Is Managed 10 -l x 10 G Flexibility Scalability 4 x ODU 1 per 10 G § 100 G PIC = 10 x 10 G lambdas = 40 x ODU 1 § Sub-wavelength bandwidth management maximizes § service delivery flexibility Super-wavelength bandwidth management supports 40 G and 100 G services Infinera Confidential and Proprietary | 8
PIC Capacity Scalability 20 -l x 20 G Flexibility Scalability § § Increase PIC scalability through: More channels (ie: from 10 to 20 lambda or more) Higher bit rates (ie: from 10 Gb/s to 20 Gb/s to 40 Gb/s) Also increasing WDM line capacity to >1 Tb/s per fiber Infinera Confidential and Proprietary | 9

Using GMPLS Restoration for Lower MTTR More Robust “Wave” Services Static Transport GMPLS-enabled GMPL S In case of failure, technician must restore service. Outage may last minutes or hours. = DWDM terminal = ROADM or WSS If spare bandwidth is available, GMPLS reroutes, providing a “quick fix” at no additional cost.
