The JBX03491 20-meter 40GBASE-SR4 QSFP+ active optical cable represents cutting-edge fiber optic technology designed specifically for enterprise-grade network applications. As a direct replacement for Dell's 470-ABMP part number, this cable delivers seamless integration into existing Dell infrastructure while providing superior performance and reliability. **Technical Excellence** This active optical cable features advanced 8-strand OM3 50/125 multimode fiber construction, optimized for 40GB data transmission over distances up to 20 meters. The OM3 multimode specification ensures compatibility with enterprise standards while supporting the high-speed requirements of modern data centers. The cable achieves full IEEE 802.3ba compliance, the industry standard for 40 Gigabit Ethernet applications. **Design and Construction** The cable employs a robust breakout architecture, converting a single QSFP+ connector input into four separate SFP+ output connectors. This configuration provides flexibility in network topology design, allowing single-port systems to distribute high-bandwidth traffic across multiple lower-speed interfaces. The LSZH (Low Smoke Zero Halogen) outer jacket meets OFNR (Riser Rated) fire code requirements, making it suitable for commercial building installations where flame and smoke ratings are mandatory. Plastic jacketing with precision fiber strand engineering ensures durability while maintaining the lightweight, flexible properties required for data center cable management. **Safety and Regulatory Compliance** Comprehensive safety certifications demonstrate this product's commitment to reliability: • Class 1 Laser Product certification ensures safe operation • UL and FDA certifications (21CFR 1040.10) verify compliance with North American standards • TÜV certification confirms European quality standards • RoHS/ELV directive compliance eliminates hazardous materials • Harmonization code 8544.70.0000 establishes proper classification **Performance Specifications** • Data Rate: 40GB (40GBASE-SR4) • Cable Length: 20 meters • Fiber Type: OM3 50/125 multimode • Form Factor: QSFP+ to 4x SFP+ breakout • Temperature Operating Range: 0-70°C (32-158°F) • Connector Type: Active optical interface **Applications and Use Cases** This cable excels in: • High-speed data center interconnections • Server-to-switch connectivity • Storage area network (SAN) implementations • Dell server and switch infrastructure • Enterprise networking backbone segments • Short-to-medium distance high-bandwidth requirements **Compatibility and Integration** Designed as a direct functional replacement for Dell part number 470-ABMP, this cable integrates seamlessly into existing Dell ecosystem deployments.
