The JBX03492 40GBASE-SR4 QSFP+ Active Optical Cable represents cutting-edge connectivity technology for high-performance enterprise networks. This 20-meter AOC is specifically engineered for Extreme Networks environments, providing a direct replacement for the OEM part number 10GB-4-F20-QSFP with superior reliability and cost-effectiveness. Key Features: This breakout cable configuration transforms a single QSFP+ connection into four independent SFP+ connections, enabling flexible network architecture expansion. The 40GB data rate supports the latest high-speed data center requirements, while the OM3 50/125 multimode fiber core optimizes signal transmission with minimal attenuation. Eight fiber strands ensure redundancy and performance consistency across demanding applications. Technical Specifications: Qualified to IEEE 802.3ba and SFF-8436 standards, the cable delivers enterprise-grade performance. The plastic jacketing with LSZH material provides enhanced fire safety compliance (OFNR rating), making it suitable for building installations without contributing to smoke or halogen emission concerns. Operating temperatures from 0-70°C accommodate most data center environments. Safety & Compliance: Comprehensive certifications including Class 1 Laser, TUV, UL/FDA (21CFR 1040.10), and RoHS/ELV directive compliance ensure safe installation and operation. These certifications provide assurance for IT managers requiring strict regulatory adherence. Applications & Use Cases: Ideal for data center interconnects, server-to-switch configurations, and network equipment expansion in enterprise environments. The 20-meter length bridges typical rack distances while maintaining signal integrity. Perfect for facilities requiring short-reach, high-bandwidth connectivity without the complexity of traditional fiber runs. Value Proposition: Offering custom brand programming availability and sourced from reliable manufacturing locations (Vietnam, China), this cable combines performance with flexibility. Free standard shipping on orders over $99 and convenient shipping from Danville, CA and Beaufort, SC locations provide rapid deployment options.
