  1. The World’s Leading Provider of Silicon Photonic Solutions BLAZAR 40 Gigabit QSFP Optical Active Cable Marek Tlalka VP of Marketing mtlalka@luxtera.com

  2. Problems with Copper Copper Cables Distort Signals More at Higher Speed 3m Twin-Ax @ 3.4Gb 6m Twin-Ax @ 3.4Gb 2 When the signal is too distorted the receiver can’t tell a 1 from a 0

  3. Fiber Solves Copper Reach Problem Single Mode Optical Fiber; Long reach and high bandwidth 1000 100 80 70 60 50 40 30 Passive Copper ~4 meters at serial 10Gbps 20 Channel Bandwidth (Gb/s) 10 9 Active Copper ~15 meters at serial 10Gbps 8 7 6 5 TwinAx (AWG 28G) active 4 TwinAx (28G) passive 3 1 300 1K+ 0 CAT5 10 20 30 40 50 Distance (m)

  4. BUT - Traditional Optics Are Expensive A 10Gb Optical Module demonstrates that “Traditional Optics” is the preverbal bag of parts with lots of hand assembly and little hope of full integration 7 key components in 5 technologies: High cost to build Laser Driver (SiGe) TOSA (Bag Of Parts) ROSA (Bag Of Parts) CDR Back Side Front Side TIA (SiGe) CMOS Micro Controller PIN Diode (InGaAs) ROSA Connection Multilayer ceramic base To support multiple components In TOSA & ROSA Challenging proximity die attach of PD & TIA Lens VCSEL Laser (GaAs) TOSA/ROSA Attachment Two Sided Hand Solder TOSA Connection Monitor PD (Si) Plastic injection molded lens ULTEM (polyethermide) Specially shaped pins to deal with High speed Signals over copper PD Laser TRIM resistor VCSEL Many Hand wire bonds inside The TOSA & ROSA

  5. Solution: Silicon CMOS Photonics Complete Optoelectronic Transceiver in One CMOS Chip Traditional Optics Luxtera’s Solution Dramatic Cost Reduction Single CMOS die

  6. Simple Design in a QSFP Package

  7. Proven 40 Gbps Performance QDR Demo with Mellanox HCAs at SC 2007 4x10GE Demo with Fulcrum Switch at OFC 2008

  8. Benefits of Blazar QDR Optical Cable High Performance Optical Connectivity High bandwidth: SDR, DDR and QDR Low latency: 12ns for 2 transceivers plus 5ns per meter Thinner, Lighter, More Flexible than Copper Increases Switch & Server Capacity per Rack Allows Fully Populated Racks Preassembled Plug and Play Solution Reduces Installation & Maintenance Cost Protects Fiber from Environmental Hazards Improved Airflow and Cooling Increases Reliability Reduces Cooling Costs Long Reach Capabilities – over 300m Enables Larger, Geographically Diverse Clusters Enables New Cluster Architectures

  9. Reach Matters! Blazar Transceivers Support up to 2 KM Reach over Single Mode Fiber at Low Cost

  10. Enables Longer Connection Distances Multimode Fiber VCSEL cables support only up to 100 meters Storage 100 Meters Switches Servers

  11. Enables Longer Connection Distances Multimode Fiber VCSEL cables support only up to 100 meters Luxtera’s Blazar supports over 300 meters (up to 2 KM) enabling new cluster architectures and ease of deployment Storage 300+ Meters Servers Switches Single Mode Fiber is ½ the Cost of Multimode Fiber

  12. Enables New Cluster Architectures < 20m Links Prevent Scaling • Top of the Rack Switch Architecture • Higher Latency • Higher cost Storage Storage Switches Server & Switch Server & Switch

  13. Enables New Cluster Architectures • Centralized Switch Architecture • Lower Latency • Lower Cost by eliminating • extra switch and cables 300 Meter Connectivity Storage Storage Switches Switch Server & Switch Server & Switch

  14. Blazar Status Volume Pre-Production: Q4 2008 Fully Qualified Production: Q1 2009 • Blazar A0: Started Sampling Q4 2007 • Blazar 1.0 (Production Version): Sampling Now • Reduced Package Size • Embedded Photo-detectors

  15. What’s Next? Aurora OptoPHY Proof of Concept Luxtera Packaged Chip Luxtera Die with FC Laser Fiber Run from Chip to Connector OptoPHY Single chip, low cost, high reliability optics on mother board Standard Connector Example: Switch Box with 12 QSFP Optical Transceivers on Motherboard 15
