The JBX03534 50-meter 40GBASE-SR4 QSFP+ to 4x SFP+ active optical cable represents cutting-edge connectivity technology for demanding networking environments. This specialized breakout AOC bridges the gap between high-density QSFP+ switching equipment and quad-channel SFP+ infrastructure, providing maximum flexibility for data center migrations and network expansions. **Technical Excellence** Built with eight precision-aligned multimode fiber strands on OM3 50/125 core specifications, this cable delivers consistent 40GB/s throughput compliant with IEEE 802.3ba standards. The active optical design eliminates the distance limitations of traditional copper solutions, making it ideal for longer-distance rack-to-rack and cabinet-to-cabinet connections within data centers. Operating across 0-70°C temperature ranges ensures stable performance in various deployment scenarios. **Safety & Compliance** Extensive safety certifications validate this cable's reliability: Class 1 Laser classification (LN #50 7/2001), UL/FDA certification under 21CFR 1040.10, and TUV verification guarantee protection for personnel and equipment. RoHS and ELV directive compliance demonstrates commitment to environmental sustainability and reduced hazardous material exposure. **Installation & Performance** The LSZH (Low Smoke Zero Halogen) jacketing prevents toxic smoke release during emergencies, critical for enclosed data center spaces. Riser-rated (OFNR) construction meets building code requirements for vertical installations. The 50-meter length accommodates large facility requirements while maintaining signal integrity that passive copper cables cannot achieve at comparable distances. **Business Advantages** As an Extreme Networks-certified compatible replacement for OEM part 10GB-4-F50-QSFP, this AOC provides significant cost savings without sacrificing quality or performance. The 90-day limited warranty and responsive customer support ensure peace of mind. Free standard shipping on orders exceeding $99 reduces total acquisition costs. **Applications** Ideal for high-performance computing clusters, cloud infrastructure, financial trading systems, media production facilities, and enterprise data center modernization projects requiring reliable 40GB connectivity.
