The JBX03437 QSFP+ active optical cable represents a premium solution for organizations requiring high-speed, reliable fiber connectivity in demanding network environments. Engineered as a drop-in replacement for the Cisco QSFP-4XLC-AOC20M, this 20-meter breakout cable combines the performance benefits of active optical technology with the flexibility of LC duplex connectors. Technical Excellence and Performance: This cable delivers exceptional 40Gbps data rates across 20 meters using OM3 50/125 multimode fiber, qualifying fully to IEEE 802.3ba specifications. The 8-strand fiber architecture supports simultaneous transmission and reception across four LC duplex pairs, enabling efficient resource utilization in space-constrained environments. Operating temperature range of 0-70°C accommodates diverse deployment scenarios from climate-controlled data centers to edge facilities. Safety and Compliance: The LSZH (Low Smoke Zero Halogen) OFNR-rated jacketing ensures compliance with fire codes and building regulations, making it suitable for plenum and riser installations. Multiple certifications including Class 1 Laser, UL/FDA 21CFR 1040.10, and TUV validate adherence to international safety standards. RoHS/ELV compliance demonstrates environmental responsibility and regulatory alignment. Deployment Advantages: Active optical cable technology eliminates the distance limitations inherent in passive copper solutions, making this ideal for campus interconnects and remote switch-to-switch connectivity. The breakout design enables cost-effective utilization of single QSFP+ ports, avoiding expensive modular transceiver solutions. Compact dimensions (12x12x20mm) minimize airflow obstruction and simplify cable management in congested patch panels. Compatibility and Flexibility: Beyond Cisco compatibility, this cable integrates with any switch or adapter supporting standard QSFP+ 40GBASE-SR4 connectors. Custom brand programming availability enables organizations to maintain consistent branding across network infrastructure. Manufactured in Vietnam and China, this cable is available with free standard shipping on orders exceeding $99. Ideal Applications: Perfect for datacenter fabric upgrades, high-speed server interconnects, campus network extensions, and environments requiring reliable 40Gbps connectivity without transceiver complexity. The 90-day limited warranty provides confidence in this critical infrastructure investment.
