The JBX03205 represents a high-performance solution for organizations requiring 400GB connectivity in modern data center architectures. As a direct Juniper QDD-4X100G-AOC replacement, this 1-meter active optical breakout cable delivers the speed and reliability necessary for next-generation network infrastructure. **Technical Excellence** Featuring OM3 50/125 multimode fiber with 16 individual fiber strands, this QSFP-DD to 4x QSFP56 breakout configuration provides flexible connectivity options. The cable supports 400GBASE-SR8 transmission standards, qualified to IEEE 802.3cm specifications and QSFP-DD MSA requirements. CMIS compatibility ensures seamless integration with modern management interfaces. **Safety and Compliance** This AOC meets stringent enterprise requirements with multiple certifications: Class 1 Laser designation, TUV approval, and FDA compliance (21CFR 1040.10). The LSZH (Low Smoke Zero Halogen) OFNR-rated jacketing prevents toxic fumes during fire events, exceeding building code requirements. Full RoHS and ELV directive compliance addresses environmental sustainability mandates. **Operational Reliability** Designed for demanding environments, the cable operates reliably across 0-70°C (32-158°F) temperature ranges. The 1-meter length provides optimal flexibility for standard rack-to-switch distances while maintaining signal integrity. Compact 12x12x2 dimensions minimize cable management complexity in dense deployments. **Ideal Applications** Perfect for enterprise data centers, cloud infrastructure upgrades, high-frequency trading environments, and research institutions requiring reliable 400GB interconnects. The multimode design excels for campus and data center deployments under 300 meters. **Support and Logistics** Shipped from U.S. facilities (Danville, CA and Beaufort, SC) with free standard shipping on orders exceeding $99. Custom brand programming is available for OEM requirements. The 90-day limited warranty provides peace-of-mind protection. As a direct Juniper compatible replacement, integration is straightforward with zero configuration complexity.
