The JBX03218 3-meter 400GBASE-SR8 QSFP-DD active optical cable represents the pinnacle of modern data center connectivity solutions. Engineered to meet the demanding requirements of enterprise networks, this breakout AOC cable provides a cost-effective alternative to traditional copper cabling while delivering superior performance and reliability. **Technical Specifications:** This cable features a QSFP-DD form factor on one end, breaking out to four individual QSFP56 connections on the opposite end. The 400GBASE-SR8 protocol ensures compatibility with the latest IEEE 802.3cm standards, making it ideal for Arista AOC-D-4Q-400G-3M replacement scenarios and equivalent deployments. **Construction & Materials:** The cable utilizes 16 strands of OM3 50/125 multimode fiber, providing optimal signal integrity over the 3-meter span. The plastic jacketing incorporates LSZH (low smoke, zero halogen) formulation rated for OFNR (optical fiber, nonconductive, riser) installations, ensuring safety compliance in commercial buildings and data centers. **Compliance & Certifications:** Fully certified under multiple safety standards including Class 1 Laser (LN #50 7/2001), TUV, UL, and FDA compliance (21CFR 1040.10). RoHS and ELV directive compliant, eliminating hazardous substance concerns in enterprise environments. **Performance Advantages:** Active optical breakout cables reduce power consumption compared to traditional 400GBASE-DR4 copper alternatives while eliminating EMI interference concerns. The compact 12x12x3 dimension profile allows for improved cable management in dense server racks. **Applications:** Ideal for hyperscale data centers, cloud infrastructure, high-performance computing clusters, and enterprise backbone networks. Compatible with Arista switches, this cable streamlines network architecture while supporting 400GB port densities. **Warranty & Support:** 90-day limited warranty covers manufacturing defects. Ships from Danville, CA or Beaufort, SC with free standard shipping on qualifying orders. Custom brand programming available for enterprise deployments requiring OEM-specific configurations. **Operating Conditions:** Designed for reliable operation between 0-70°C (32-158°F), accommodating diverse data center environments from edge installations to core infrastructure deployments.
