## 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, 1+1 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

## 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
- ≥ 100 Gbps concatenated Channels (Nx100 GbE)
- ≥ 10 Tbps optical line systems
- Integrated multi-domain (L3/2/1) IP/DWDM optical networks

## 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

## Moore’s Law For ICs Predicted to Continue...→ PICs Allow Optics To Keep Up

- 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

- Semiconductor Industry’s International Technology Roadmap for Semiconductors (ITRS)

## 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 industry’s first project on the way to 100 GbE
- Many new technologies will need to be developed...
- Though 100 Gbps PIC optics is already proven

## 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

## 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 Moore’s Law
