The JBX03394 7-meter 400GBASE-SR8 QSFP-DD active optical cable represents the gold standard in high-speed data center connectivity. Engineered specifically for NVIDIA Mellanox ecosystems, this premium interconnect solution delivers exceptional performance for hyperscale data centers, cloud infrastructure, and enterprise networking environments requiring 400GB bandwidth. **Technical Specifications:** This advanced AOC utilizes 16 multimode fiber strands in the industry-standard OM3 50/125 configuration, enabling reliable 400GBASE-SR8 transmission over distances up to 7 meters. The cable achieves full compliance with IEEE 802.3cm standards and QSFP-DD Multi-Source Agreement (MSA) specifications, ensuring seamless integration with existing infrastructure. **Safety & Compliance:** The LSZH (Low Smoke Zero Halogen) OFNR-rated jacketing prioritizes workplace safety while maintaining flame resistance. The cable carries comprehensive certifications including Class 1 Laser approval, UL/FDA compliance per 21CFR 1040.10, and TUV verification. Full RoHS/ELV directive compliance (EU 2002/95/EC) confirms environmental responsibility. **Compatibility & Replacement:** Direct replacement for NVIDIA Mellanox OEM part numbers C-DQ8FNM007-H0-M, MFA1W00-W007, and C-DQ8FNM007-NML. Compatible with all NVIDIA Mellanox QSFP-DD transceivers and switches supporting 400GBASE-SR8 protocols. **Performance Characteristics:** Operates reliably between 0-70°C (32-158°F), accommodating diverse data center thermal conditions. The plastic jacketing with integrated fiber strands minimizes installation footprint while maintaining structural integrity. **Support & Warranty:** Backed by a comprehensive 90-day limited warranty and available for custom brand programming. Ships from strategically located U.S. distribution centers (Danville, CA and Beaufort, SC) with free standard shipping on orders exceeding $99. **Applications:** Ideal for high-density server interconnects, switch-to-switch fabric connections, and direct-attached storage (DAS) deployments in modern data centers.
