The JBX03447 50m Cisco QSFP+ Active Optical Cable represents a premium solution for organizations requiring high-speed fiber connectivity in their network infrastructure. This 40GBASE-SR4 compatible AOC is engineered to replace Cisco's QSFP-4XLC-AOC50M, providing seamless integration into existing enterprise deployments while delivering superior performance and reliability. **Technical Excellence**: Built with eight strands of OM3 50/125 multimode fiber, this cable achieves 40GB data transmission speeds while maintaining exceptional signal quality across its full 50-meter length. The OM3 specification ensures compatibility with modern datacenter standards and provides headroom for future bandwidth requirements. IEEE 802.3ba qualification guarantees compliance with the latest networking standards, while the SFF-8436 form factor ensures mechanical compatibility across devices. **Safety and Compliance**: The LSZH (Low Smoke Zero Halogen) riser-rated (OFNR) jacket exceeds fire safety requirements, making it ideal for installation in building plenum spaces where airflow circulation occurs. Comprehensive certifications including Class 1 Laser, TUV, UL/FDA 21CFR 1040.10, and full RoHS/ELV directive compliance demonstrate adherence to global safety and environmental standards. **Flexible Connectivity**: The QSFP+ to 4x LC duplex breakout design enables sophisticated network architectures, allowing single high-speed connections to split into four independent channels for maximum flexibility in equipment placement and cable management. **Practical Advantages**: Operating reliably across 0-70°C temperature ranges, this cable performs consistently in diverse environments from climate-controlled datacenters to field deployments. The plastic jacketing with reinforced fiber construction withstands handling rigors while maintaining structural integrity. Custom brand programming options allow organizations to standardize cables with proprietary identification. **Deployment Applications**: Ideal for datacenter interconnects, enterprise backbone networks, high-speed server connections, and network switch uplinks where reliable 40GB connectivity over 50 meters is essential. The breakout configuration supports modern distributed architecture patterns where single cables serve multiple connection points. **Value Proposition**: Backed by a 90-day limited warranty and featuring free standard shipping on orders exceeding $99, this cable delivers enterprise-grade performance without premium pricing. Manufactured in Vietnam and China with quality oversight ensuring consistency, the JBX03447 provides dependable connectivity for mission-critical network operations.
