Who is Infinera?

• What does Infinera do?
• Digital Optical Networks
• Multiwavelength scale of DWDM digital bandwidth
  management
• How do we do it?
• Photonic Integrated Circuits make OEO of hundreds
  of Gbps affordable, enabling true digital
  networking
• Why does it matter?
• Digital networks enable simple, rapid
  scalability..
• Fast flexible service provisioning
• and highly manageable networks
• How real is it?
• First customers went live in December 2004
• Infinera DTN now carrying live traffic in
  multiple networks around the world

Optical Services Evolution

• Today
• SONET OC-3 to OC-192
• Ethernet 1 and 10 GbE
• Static, manually configured, unprotected
  point-to-point links and rings
• Unprotected wavelengths, 11 optical protection
• Completely independent layer from Ethernet and IP
  with little communication between layers
  preventing optimization
• Within 5 Years
• SONET OC-768/OC-768c
• Ethernet 100 and Nx100 GbE (Nx TbE?)
• Dynamic, on-demand, GMPLS controlled bandwidth
• Optical (L1) VPNs
• Rich variety of Protection and Restoration
  options for hub-and-spoke access networks through
  meshed core networks
• Tight integration with Ethernet and IP layers

5
Optical Technologies Evolution

• Yesterday
• Small scale, single 10 Gbps channel integration
• 10 Gbps channels
• 320-800 Gbps optical line systems
• Dispersion Compensation Fiber (DCF)
• No control plane or Bandwidth Management for
  wavelength services
• Static point-to-point optical links, rings and
  OADMs
• Distinct Access / Metro / LH / ULH optical
  transport solutions
• No IP awareness
• Today
• Improved economics through 100 Gbps large scale
  photonic integration
• Electronic Dispersion Compensation (EDC)
• End-to-end GMPLS control plane
• Reconfigurable OADMs with wavelength interchange
• Dynamic meshed optical networks with flexible
  Bandwidth Management for wavelength services
• Integrated Access / Metro / LH / ULH optical
  transport solutions
• Within 5 Years
• 1.6 Tbps very large scale photonic integration
• 40 Gbps individual channels

6
Key Interoperability Issues

• Interfaces
• 10 GbE LAN PHY OAM (IEEE 802.1, ITU, etc.)
• 100 GbE (IEEE)
• Control Plane
• Basic IETF GMPLS UNI
• Advanced IETF GMPLS UNI w/advanced Protection and
  Restoration capabilities
• Multi-domain GMPLS integration

7
Moores Law For ICs Predicted to Continue? PICs
Allow Optics To Keep Up
Semiconductor Industrys International Technology
Roadmap for Semiconductors (ITRS)

• 65 nm and below Si focused on more integration
  with lower power, more so than higher speeds (as
  with previous gens)
• Alternative signaling schemes required (e.g. more
  wavelengths, more bits/hertz), not just higher
  NRZ TDM bit rates

8
100 GbE Development Has Begun

• The standard for 10 GbE was approved in 2002
  after a 3-year development cycle
• Work on 10 GbE began in 2000
• Ethernet performance has advanced approximately
  10x every four years
• Work on 100 GbE should have started in 2004
• The OIF recently approved the industrys first
  project on the way to 100 GbE
• Many new technologies will need to be developed
• Though 100 Gbps PIC optics is already proven

9
The GMPLS Revolution

• GMPLS has a lot of promise for dynamic control
  planes, optical VPNs, optical layer protection
  and multi-domain integration, but has seen little
  carrier deployment until recently
• Much more work remains to be done before the
  GMPLS UNI delivers true economic value, is
  interoperable, and is universally deployed

10
Summary

• Next-gen optical and IP services require a more
  flexible transport layer
• Optics enables capacity scalability (DWDM) and
  reach (optical amplifiers)
• OEO combined with electronics software are
  necessary for everything else
• Photonic Integrated Circuits enable economical
  OEO that keeps pace with Moores Law
