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

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
