The JBX03291 20m 400GBASE-SR8 QSFP-DD Active Optical Cable represents enterprise-grade interconnect technology designed for modern data center environments requiring ultra-high-speed, reliable fiber optic transmission. This advanced AOC solution leverages 16 strands of OM3 50/125 multimode fiber to achieve full 400GB throughput, making it ideal for connecting high-density switch ports, server arrays, and storage systems in demanding network architectures. Key Technical Features: This cable is specifically engineered for 400GBASE-SR8 applications, supporting simultaneous 50GB channels across 8 independent fiber pairs. The QSFP-DD (Quad Small Form Factor Pluggable Double Density) form factor provides maximum port density while maintaining signal integrity. With 20 meters of transmission distance, it accommodates flexible data center layouts without requiring signal regeneration. The OM3 multimode specification ensures compatibility with existing infrastructure while delivering future-proof performance. Safety & Compliance: Manufactured to international standards including IEEE 802.3cm and QSFP-DD MSA specifications, this cable integrates Class 1 Laser safety features and meets RoHS/ELV directives. The LSZH jacketing composition minimizes toxic smoke and halogen emissions in case of fire, critical for enclosed data center spaces. UL/FDA certification and TUV validation confirm compliance with telecommunications safety protocols. The cable's OFNR (Optical Fiber Non-conductive Riser) rating permits installation in vertical cable runs and plenum areas. Performance Benefits: Active optical technology eliminates signal degradation associated with passive copper alternatives, enabling error-free transmission at maximum distances. The low-power consumption design reduces cooling requirements compared to conventional electrical solutions. Operating temperature range of 0-70°C accommodates standard and elevated data center conditions. Application Scenarios: Perfect for enterprise data centers, cloud infrastructure, high-performance computing clusters, and financial trading environments where 400GB connectivity is essential. Ideal as a direct replacement for Cisco QDD-400-AOC20M installations. Supports both new deployments and phased network upgrades. Shipping & Support: Ships from strategically located US warehouses in Danville, CA and Beaufort, SC for rapid delivery. Custom brand programming enables white-label solutions for resellers. Backed by 90-day limited warranty and responsive customer support.
