The JBX03227 represents a cost-effective, high-performance solution for enterprises requiring 400GB breakout connectivity in modern data center environments. As a direct replacement for Arista's AOC-D-4Q-400G-7M, this 7-meter active optical cable seamlessly integrates into existing network infrastructure while offering superior reliability and performance. **Technical Specifications:** This breakout AOC features a single QSFP-DD 400GB interface that splits into four independent QSFP56 100GB ports, enabling granular bandwidth distribution and flexible network segmentation. The cable utilizes 16-strand OM3 50/125 multimode fiber technology, specifically engineered for high-speed data transmission in short to medium-distance applications. At 7 meters, the cable length provides adequate reach for intra-rack and adjacent cabinet deployments without signal degradation. **Performance & Compliance:** Fully qualified to IEEE 802.3cm specifications and QSFP-DD MSA standards, this cable delivers 400GB/s aggregate throughput with minimal latency. The OFNR LSZH (Low Smoke Zero Halogen) jacketing combines fire safety with environmental responsibility, eliminating halogenic compounds that produce corrosive gases during combustion. RoHS and ELV directive compliance ensure hazardous substance restrictions are met. **Safety & Reliability:** Comprehensive safety certifications including Class 1 Laser, TUV, UL, and FDA approvals (21CFR 1040.10) guarantee safe operation in professional environments. Extended operating temperature range (0-70°C) ensures consistent performance across diverse deployment scenarios. **Use Cases:** Ideal for data centers, high-performance computing clusters, cloud infrastructure, and enterprise networking requiring flexible 400GB-to-100GB breakout capabilities. Perfect for network backbone upgrades, storage array interconnects, and campus area network extensions. **Warranty & Support:** Backed by a 90-day limited warranty and available for shipment from multiple US locations (Danville, CA and Beaufort, SC). Custom brand programming available for organizations requiring OEM-specific configurations.
