The JBX03446 3-meter 40GBASE-SR4 QSFP+ active optical cable represents an excellent solution for enterprises requiring high-speed, reliable optical connectivity in their Juniper-based network infrastructure. As a direct replacement for the Juniper OEM part number JNP-QSFP-4XLC-3M, this AOC maintains full compatibility with Juniper switching and routing equipment while offering superior value. Key Features and Specifications: This breakout cable utilizes a single QSFP+ form factor connector on one end that fan-outs to four individual LC duplex connectors, enabling efficient bandwidth distribution across multiple network ports. The 8-strand OM3 50/125 multimode fiber core supports 40GB data rates per IEEE 802.3ba specifications, making it suitable for short-to-medium distance deployments up to 300 meters. Operating temperature range from 0-70°C ensures reliable performance across diverse data center and enterprise environments. Technical Advantages: The active optical cable design incorporates integrated signal conversion and amplification, eliminating signal degradation over the 3-meter distance. OM3 multimode fiber reduces infrastructure costs compared to single-mode alternatives while maintaining excellent performance for modern 40G applications. The LSZH (Low Smoke Zero Halogen) OFNR (Optical Fiber Non-conductive Riser) rated jacket provides superior fire safety and environmental compliance, meeting stringent building codes and regulations. Compliance and Certification: Full RoHS/ELV directive compliance ensures environmental responsibility and regulatory adherence. Multiple safety certifications including UL/FDA 21CFR 1040.10, Class 1 Laser, TUV, and LN #50 7/2001 demonstrate this cable's meeting of international safety standards. These certifications provide confidence in deployment across regulated environments including hospitals, financial institutions, and government facilities. Applications and Use Cases: Perfect for data center upgrades, campus network expansions, and high-performance computing environments. Ideal for organizations standardizing on Juniper equipment seeking reliable spare inventory or expansion cables. Reduces deployment time and complexity with plug-and-play compatibility. Warranty and Support: 90-day limited warranty provides peace of mind. Free standard shipping on orders exceeding $99 from multiple distribution centers in California and South Carolina ensures rapid delivery.
