6. 6 Simple Design in a QSFP Package

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

8. 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. 9 Reach Matters! Blazar Transceivers Support up to 2 KM Reach over Single Mode Fiber at Low Cost

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

11. 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 Servers Switches Storage 300+ Meters Single Mode Fiber is ½ the Cost of Multimode Fiber

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

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