The JBX03523 represents a sophisticated solution for enterprises seeking cost-effective, high-performance connectivity in 40GB network environments. This 3-meter Active Optical Breakout Cable (AOC) is specifically engineered to replace Arista's AOC-Q-S-40G-3M, offering identical performance characteristics while providing exceptional value for data center operators and network integrators. **Technical Excellence**: Operating at 40 gigabits per second, this QSFP+ to 4x SFP+ breakout cable utilizes eight strands of OM3 50/125 multimode fiber, delivering superior signal fidelity over the 3-meter distance. The IEEE 802.3ba and SFF-8436 certifications guarantee compatibility with leading network switches and equipment from Arista and other manufacturers. **Safety & Compliance**: The cable features comprehensive safety certifications including Class 1 Laser approval, TUV validation, and UL/FDA compliance (21CFR 1040.10). The OFNR (Optical Fiber Non-conductive Riser) LSZH jacketing provides fire resistance and low-smoke characteristics essential for plenum installations and enclosed cable runs. **Durability & Reliability**: Constructed with high-quality plastic jacketing and premium fiber components, this cable operates reliably across the 0-70°C temperature range. Its rugged design withstands the demands of busy data centers while the low-loss fiber optic technology ensures minimal signal degradation. **Installation & Support**: The breakout architecture allows single QSFP+ ports to connect four separate 10GB SFP+ devices, maximizing port utilization and reducing infrastructure costs. Shipped from multiple U.S. locations (Danville, CA and Beaufort, SC), eligible orders enjoy free standard shipping on purchases exceeding $99. The 90-day limited warranty provides customer protection and manufacturer support. **Applications**: Ideal for data center upgrades, cloud infrastructure expansion, and high-performance computing environments where 40GB connectivity demands flexibility and reliability.
