The JBX03199 represents an optimal solution for organizations seeking to upgrade their data center infrastructure with high-capacity optical connectivity. This 10-meter 400GBASE-SR8 QSFP-DD active optical cable is specifically engineered as a direct replacement for Juniper's QDD-4X100G-AOC-10M, offering exceptional compatibility and performance. **Technical Specifications & Features:** This breakout cable configuration transitions a single QSFP-DD 400GB port into four independent QSFP56 100GB lanes, enabling flexible port expansion without requiring additional switching hardware. The 16-strand OM3 50/125 multimode fiber core provides excellent bandwidth capacity while maintaining cost efficiency compared to singlemode alternatives. Operating across temperatures from 0 to 70°C (32 to 158°F), the cable performs reliably in diverse data center climates. **Safety & Compliance:** Fully RoHS and ELV compliant, the JBX03199 meets stringent EU directive 2002/95/EC requirements. Safety certifications include Class 1 Laser classification, UL/FDA approval, and TUV verification, ensuring safe operation in production environments. The LSZH (Low Smoke Zero Halogen) OFNR (Optical Fiber Non-conductive Riser) jacketing provides enhanced fire safety, making it suitable for elevated installation in commercial buildings. **Standards Compliance:** Qualified to IEEE 802.3cm specifications and QSFP-DD MSA standards, this cable ensures interoperability across certified equipment. The plastic jacketing with 16 fiber strands provides durability while maintaining optimal light transmission characteristics. **Applications:** Ideal for data center expansions, high-performance computing clusters, and enterprise network upgrades where Juniper equipment is deployed. The 10-meter length provides flexibility for mid-range intra-rack and cross-rack connectivity scenarios. **Shipping & Support:** Enjoy free standard shipping on orders exceeding $99. The cable includes a 90-day limited warranty and is backed by custom brand programming availability for enterprise deployments. Manufactured in Vietnam and China with quality assurance standards applicable to optical fiber communications products (Harmonization Code 8544.70.0000).
