The JBX03226 represents cutting-edge connectivity technology for modern high-speed networking environments. This 5-meter 400GBASE-SR8 QSFP-DD to 4x QSFP56 active optical breakout cable is engineered specifically as a drop-in replacement for Juniper's QDD-4X100G-AOC-5M transceiver modules, offering seamless compatibility with Juniper-based network infrastructure. **Technical Specifications:** This breakout AOC utilizes 16 strands of OM3 50/125 multimode fiber, supporting 400GB data rates across IEEE 802.3cm specifications. The cable maintains CMIS (Common Management Interface Specification) compliance, enabling intelligent management capabilities alongside traditional network monitoring. With dimensions of 12x12x5mm, the compact form factor optimizes port density on network switches and routers. **Safety & Compliance:** The LSZH jacketing eliminates toxic gases and heavy metals during combustion, making this cable ideal for enclosed spaces and vertical installations. Comprehensive safety certifications including UL, FDA 21CFR 1040.10, TUV, and Class 1 Laser compliance ensure safe operation in any environment. RoHS/ELV compliance confirms environmental responsibility and global regulatory adherence. **Performance & Reliability:** Operating across the full industrial temperature range of 0-70°C (32-158°F), this cable delivers consistent performance in diverse deployment scenarios. The active optical design eliminates signal degradation over the 5-meter distance, making it ideal for intra-rack and inter-cabinet connectivity within data centers. **Applications:** Perfect for hyperscale data centers, cloud service providers, enterprise campus networks, and financial trading environments requiring ultra-reliable 400GB connectivity. The breakout configuration allows efficient distribution of 400GB ports to four 100GB channels, optimizing network architecture flexibility. **Shipping & Support:** Enjoy free standard shipping on orders over $99, with convenient shipment from domestic warehouses in Danville, CA or Beaufort, SC. Backed by a 90-day limited warranty and custom programming options for branded deployments. RoHS compliant manufacturing from Vietnam and China ensures quality and cost-effectiveness.
