The JBX03185 400G QSFP-DD active optical cable represents a cutting-edge solution for modern data center infrastructure requiring high-speed, reliable connectivity. This 15-meter breakout cable is engineered to meet the demands of next-generation network architectures while maintaining full backward compatibility with existing Cisco equipment. Technical Specifications: This cable features a QSFP-DD (Quad Small Form Factor Pluggable Double Density) form factor that breaks out into 4 individual QSFP28 connections, enabling flexible network configurations. With OM3 50/125 multimode fiber and 16 strands, the cable delivers 400GBASE-SR4.2 performance up to 15 meters, making it ideal for intra-datacenter connections between switches, routers, and high-performance computing systems. Performance & Reliability: Qualified to IEEE 802.3bs specifications and QSFP-DD MSA standards, this AOC (Active Optical Cable) provides superior performance compared to traditional copper alternatives. The integrated optical-to-electrical conversion circuitry ensures minimal signal degradation, enabling true plug-and-play operation with Cisco networking equipment. Operating temperature range of 0°C to 70°C accommodates standard data center environments. Compliance & Safety: The OFNR (Riser Rated) LSZH (Low Smoke Zero Halogen) jacketing meets stringent building codes and fire safety requirements. Full RoHS and ELV compliance ensures environmental responsibility, while UL/FDA and Class 1 Laser certifications guarantee safe operation in professional settings. Application Use Cases: • Data center network upgrades from 100G to 400G • High-performance computing cluster interconnections • Storage area network (SAN) modernization • Enterprise campus network backbone expansion • Service provider infrastructure upgrades Value Proposition: Compared to longer-distance single-mode alternatives or power-consuming active copper cables, this OM3 multimode AOC offers the optimal balance of cost, performance, and power efficiency for medium-range connections. The Cisco QDD-4X100G-AOC15M compatibility ensures seamless integration without requiring firmware updates or compatibility verification. Warranty & Support: Backed by a comprehensive 90-day limited warranty with fast shipping from US distribution centers in California and South Carolina. Custom brand programming available for enterprise deployments.
