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
