The JBX03250 10-meter 400GBASE-SR8 QSFP-DD Active Optical Cable represents the cutting edge of high-speed data center connectivity. Purpose-built for Arista-based network infrastructures, this premium AOC delivers exceptional performance in mission-critical environments where reliability and speed are paramount. **Technical Excellence:** Features 16 individual fiber strands within OM3 50/125 multimode construction, enabling 400GB data rate transmission over the 10-meter length. Qualified to IEEE 802.3cm and QSFP-DD MSA specifications, ensuring seamless integration with compatible network hardware. The active optical design eliminates signal degradation over extended distances while consuming minimal power. **Safety & Compliance:** Manufactured with LSZH jacketing to prevent toxic smoke and corrosive gases during potential fires—critical for enclosed data center spaces. OFNR (Riser-rated) construction permits installation through vertical cable trays and between floors. Comprehensive certifications include TUV, UL/FDA 21CFR 1040.10 laser safety, and full RoHS/ELV directive compliance for environmental responsibility. **Deployment Advantages:** The 10-meter length bridges standard rack-to-switch distances without requiring intermediate connectors that introduce signal loss. Superior to traditional copper cabling in electromagnetic interference immunity and heat generation. Operates reliably across 0-70°C temperature range, accommodating diverse data center environments. **Compatibility & Support:** Dropin replacement for Arista P/N AOC-D-D-400G-10M. Ships from US locations (Danville, CA or Beaufort, SC) with complimentary standard shipping on qualifying orders. Supported by 90-day limited warranty and responsive customer service. **Ideal Applications:** Data center switch interconnects, high-performance computing clusters, cloud infrastructure, enterprise campus networks, and any environment requiring reliable multi-hundred-gigabit connectivity. The sealed, tested design eliminates field installation variables, reducing troubleshooting overhead.
