The JBX03373 5-meter 400GBASE-SR8 QSFP-DD active optical cable represents the ideal solution for modern data centers and enterprise networks transitioning to 400GB connectivity standards. Built specifically for Dell infrastructure, this cable replaces OEM part numbers 470-ACTI and 470-ACUB while offering superior compatibility and performance metrics. **Technical Specifications:** This active optical cable features 16-strand OM3 50/125 multimode fiber capable of supporting 400GB per second data transmission rates. The QSFP-DD (Quad Small Form Factor Pluggable Double Density) form factor maximizes port density while maintaining backwards compatibility with existing infrastructure investments. At 5 meters in length, it provides optimal flexibility for intra-rack and inter-rack connectivity without excessive cable management complexity. **Safety & Compliance:** The cable meets stringent industry safety standards including Class 1 Laser certification, TUV approval, UL/FDA 21CFR 1040.10 compliance, and EU RoHS/ELV directives. The LSZH (low-smoke, zero-halogen) OFNR (Optical Fiber Non-conductive Riser) rated jacketing ensures enhanced fire safety and reduced toxic emissions in case of combustion, critical for enclosed data center environments. **Performance & Reliability:** Qualified to IEEE 802.3cm specifications and QSFP-DD MSA/CMIS standards, this cable delivers consistent 400GB performance across operating temperatures of 0 to 70°C (32 to 158°F). The active optical cable technology provides superior signal integrity compared to passive alternatives, reducing latency and ensuring reliable data transmission in high-density deployments. **Applications:** Ideal for hyperscale data centers, cloud infrastructure, financial trading platforms, and enterprise storage networks requiring sub-microsecond latency and maximum throughput. The cable supports multiple vendors while maintaining Dell system optimization, making it a versatile choice for hybrid infrastructure environments. **Warranty & Support:** Backed by a 90-day limited warranty with custom brand programming available for enterprise deployments. Ships from convenient US locations (Danville, CA and Beaufort, SC) with free standard shipping on orders exceeding $99, ensuring rapid deployment without additional logistics costs.
