The JBX03489 Active Optical Cable represents a cutting-edge solution for modern data center infrastructure requiring high-bandwidth, reliable connectivity. This 20-meter 40GBASE-SR4 QSFP+ to quad SFP+ breakout cable is engineered specifically for compatibility with Arista AOC-Q-S-40G-20M equipment, making it an ideal replacement or upgrade component for existing network deployments. Technical Specifications & Performance: This cable operates at 40GB data rates using the 40GBASE-SR4 protocol, utilizing OM3 50/125 multimode fiber cores across 8 strands for superior signal fidelity. The active optical cable architecture eliminates signal degradation over longer distances, making the 20-meter length suitable for extensive data center layouts without requiring expensive signal conditioning equipment. IEEE 802.3ba qualification ensures complete interoperability with standards-compliant networking infrastructure. Safety & Compliance: The LSZH (Low Smoke Zero Halogen) jacketing with OFNR (Optical Fiber Non-Conductive Riser) rating meets stringent fire safety codes required in commercial and data center environments. Full RoHS/ELV compliance and EU directive 2002/95/EC adherence make this cable suitable for environmentally-conscious organizations. Class 1 Laser certification, UL/FDA compliance, and TUV certification ensure operator safety and regulatory compliance. Applications & Use Cases: Ideal for network architects deploying high-performance computing clusters, storage area networks (SANs), or expanding existing Arista-based infrastructure. The breakout configuration enables efficient bandwidth management, allowing single 40GB connections to be distributed to multiple 10GB devices. Operating temperature range of 0°C to 70°C accommodates standard data center environments without thermal management complications. Quality Assurance: Each cable ships with a 90-day limited warranty, backed by US-based fulfillment from Danville, CA and Beaufort, SC locations. Free standard shipping on orders exceeding $99 reduces total deployment costs. Custom brand programming is available for organizations requiring proprietary labeling or specific network documentation requirements. This premium-grade active optical cable delivers the reliability, performance, and compliance standards demanded by enterprise-grade network infrastructures while maintaining cost-effectiveness for large-scale deployments.
