  1. Impact of Photonic Integration on Optical Services Serge Melle VP Technical Marketing, Infinera

  2. 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.

  3. 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

  4. Scalability Challenges • Service scaling: • Evolution to 40G and 100GbE services • Network scaling: • >1Tb/s per fiber • Nodal scaling • System size for >Tb/s nodes • Operations • Deployment, fibers, spares,

  5. 100 Gb/s Transmit 100 Gb/s Receive WDM Systems Today Single WDM channel - - - - - - - - - - - - - - - - times 32, 40 or 80 wavelengths

  6. 100 Gb/s Transmit 100 Gb/s Receive Photonic Integrated Circuit Innovation 100Gb/s Transmit 100Gb/s Receive 5mm • 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

  7. 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 Impact of PIC Technology Line Trib Transponder Line Trib

  8. How PIC Capacity Is Managed Scalability 10-l x 10G • 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 Flexibility 4 x ODU1 per 10G

  9. PIC Capacity Scalability Scalability 20-l x 20G • 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 Flexibility

  10. 1.6Tbit/s DWDM Large-Scale PIC Transmitter Announced at OFC 2006… …40 channels x 40 Gb/s

  11. Service Opportunities Transition to Ethernet • Bandwidth on Demand • Layer 1 Optical VPNs • UNI-based inter-network signaling New Service Opportunities Speed as a Sales Advantage • New Transport Services • 40G and 100GbE • Restorable bandwidth • Sub-lambda Switching

  12. Short Term Capacity Lease“Pay for Connectivity Only When You Need It” Optical Transport “Cloud” UNI UNI 10G “Port” UNI UNI UNI UNI Phase 2: GMPLS UNI automated provisioning Phase 1: Human provisioning

  13. Layer 1 VPN“A secure, private optical network without owning physical assets” Customer 1 Customer 2 EMS 1 1 GMPLS 2 2 Complementary to a dynamically allocated service 1

  14. 1 and 10GbE Lightpaths“Ethernet cost with SDH Manageability and Quality” Optical Transport “Cloud” • 10GbE: LAN PHY preferred to save router/switch port cost • Full transparency • Optional restoration (differentiate vs. “wavelength” service) DB DB DB DB DB DB  10GbE LAN PHY  DB DB DB

  15. 1-port 40G 40G over 4-port 10G 40G Super-Lambda Service40G IP Backbone Without Re-Architecting the Optical Network OC-768/STM-256 capacity router-to-router • Full 40G link utilization without 40G WDM link engineering or cost • Common transport network supports 40G router-router traffic • 40G service using either 1 x 40G or 4 x 10G router blades • Optional GMPLS restoration maximizes service SLAs 4 x 10G across the optical network Optical Transport “Cloud”

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