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

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

Impact of PIC Technology
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

How PIC Capacity Is Managed
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

PIC Capacity Scalability
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
