The JBX03137 5-meter 800GBASE-SR8 QSFP-DD active optical cable represents a cutting-edge solution for modern high-density data center networking requirements. As a direct replacement for the Arista A-D800-2Q400-5M component, this cable delivers seamless integration into existing Arista switch infrastructure without compatibility concerns. Technical Excellence and Performance: This breakout-style active optical cable utilizes advanced 16-strand OM3 50/125 multimode fiber technology, engineered to sustain 800Gbps data transmission rates across its full 5-meter length. The QSFP-DD form factor provides superior density advantages, allowing network architects to maximize port density while maintaining signal integrity. The cable's multimode fiber composition makes it ideal for shorter-reach connections typical in intra-rack and inter-rack communications within data center environments. Construction and Safety Features: The cable features robust plastic jacketing with LSZH (Low Smoke Zero Halogen) composition, meeting OFNR (Optical Fiber Non-Conductive Riser) ratings. This construction minimizes smoke and toxic fume production in case of fire, making it suitable for plenum-adjacent and riser installations. Comprehensive safety certifications including Class 1 Laser safety, UL/FDA compliance per 21CFR 1040.10, and TUV approval ensure workplace safety standards are met. Compliance and Environmental Responsibility: Full RoHS and EU directive 2002/95/EC compliance ensures this cable meets stringent environmental and hazardous substance restrictions. The cable operates reliably within 0-70°C temperature ranges, accommodating varied data center climate conditions. Manufactured in Vietnam and China with quality control standards, the product provides confidence in reliability and performance longevity. Applications and Use Cases: Ideal for network operators upgrading to 800G infrastructure, this cable supports mission-critical applications including high-performance computing clusters, cloud infrastructure, and enterprise data centers. The Arista compatibility ensures plug-and-play deployment without firmware or configuration modifications. Warranty and Support: Backed by a 90-day limited warranty and featuring free standard shipping on orders exceeding $99, this solution delivers exceptional value with professional support infrastructure.
