The JBX03433 15-meter QSFP+ to 4x LC duplex active optical cable represents a premium connectivity solution for high-performance networking infrastructure. Engineered as a direct replacement for Cisco's QSFP-4XLC-AOC15M, this breakout AOC cable delivers exceptional value for data center operators and network engineers seeking reliable 40 Gigabit Ethernet transmission. **Technical Excellence:** Built with OM3 50/125 multimode fiber and 8 individual fiber strands, this cable supports the 40GBASE-SR4 standard, delivering full-duplex 40 Gbps performance. The active optical design eliminates signal degradation over extended distances while consuming minimal power compared to electrical alternatives. IEEE 802.3ba qualification ensures compatibility with current and legacy network infrastructure. **Safety & Compliance:** The cable features LSZH (Low Smoke Zero Halogen) rated OFNR jacketing, meeting stringent fire safety requirements for commercial buildings. Full RoHS/ELV compliance and UL/FDA certifications demonstrate adherence to international safety standards. Class 1 Laser certification ensures safe operation in production environments. **Practical Applications:** Ideal for data center spine-leaf architectures, campus backbone networks, and high-speed storage area networks requiring breakout connectivity. The 15-meter length accommodates typical rack-to-rack distances without signal loss. Four simultaneous 10 Gbps connections via individual LC ports enable flexible resource allocation and simplified cable management. **Durability & Support:** With a 90-day limited warranty and operation across 0-70°C temperature ranges, this cable withstands demanding installation environments. Custom brand programming is available for enterprise customers requiring OEM branding. Ships from multiple US locations with free standard shipping on orders over $99. **Why Choose This AOC?** Active optical cables provide superior performance-per-watt and future-proof your infrastructure investment. The QSFP+ format maximizes port density on modern switches, while the LC breakout configuration offers maximum flexibility for migration scenarios and mixed-vendor deployments.
