The JBX03540 5-meter QSFP+ active optical cable represents cutting-edge connectivity for modern data center infrastructure. Designed as a drop-in replacement for Cisco's QSFP-4X10G-AOC5M, this breakout cable combines superior performance with unmatched reliability. **Technical Excellence:** This cable features eight strands of OM3 50/125 multimode fiber optimized for 40GBASE-SR4 transmission. The active optical technology eliminates signal degradation over 5-meter runs, making it ideal for intra-rack and short-haul interconnections. Each of the four SFP+ ports delivers independent 10GB channels, enabling flexible bandwidth allocation across your network. **Safety & Compliance:** The LSZH (Low Smoke Zero Halogen) jacket with OFNR (Optical Fiber Non-conductive Riser) rating meets stringent building codes and fire safety standards. Full RoHS and EU directive 2002/95/EC compliance ensures environmental responsibility. Certified for Class 1 Laser safety with UL/FDA approvals and comprehensive TUV certification. **Enterprise-Grade Performance:** Operating reliably across 0-70°C temperature ranges, this cable handles demanding server room environments. The 12x12x5mm compact connector profile minimizes panel space while maintaining maximum throughput. IEEE 802.3ba qualification guarantees compatibility with next-generation switching infrastructure. **Real-World Applications:** Perfect for connecting QSFP+ switch ports to multiple SFP+ transceivers in blade server environments, virtualized data centers, and high-frequency trading floors. The breakout configuration provides cost-effective scaling without replacing entire network infrastructure. **Warranty & Support:** Backed by a 90-day limited warranty with free standard shipping on orders over $99. Ships from domestic US locations (Danville, CA and Beaufort, SC) ensuring rapid deployment. Custom brand programming available for OEM requirements.
