The JBX05218 represents a cutting-edge solution for enterprise networking professionals requiring high-speed, reliable connectivity. This 3-meter passive breakout DAC (Direct Attach Copper) cable transforms a single 40GBASE-CR4 QSFP+ connection into four independent 10GBASE-SFP+ channels, maximizing equipment flexibility without additional hardware investment. Designed as a direct replacement for Arista's CAB-Q-S-3M, this cable maintains full compatibility with Arista network switches and infrastructure. The 30AWG twinax copper construction ensures superior signal quality and minimal electromagnetic interference, critical factors in high-speed data transmission. Unlike active breakout solutions, this passive cable requires zero power consumption, reducing operational costs and complexity while virtually eliminating latency concerns. Key Technical Features: - IEEE 802.3ba qualified for 40GBASE-CR4 standards - SFF-8436 form factor compliance - Operating temperature range: 0-70°C (32-158°F) - Comprehensive RoHS/ELV compliance for environmental responsibility - TUV and UL safety certifications - Copper connectors with plastic jacketing for durability Ideal Applications: Data center upgrades, server interconnects, cloud infrastructure, network switching fabric, and enterprise backbone configurations requiring cost-effective, low-latency multi-channel connectivity. The JBX05218 offers exceptional value for organizations modernizing their network infrastructure. Its passive design eliminates compatibility headaches and power management concerns while delivering proven reliability. Backed by a 90-day limited warranty and available custom programming options, this cable is ready for immediate deployment. With free standard shipping on qualifying orders and availability from multiple US distribution centers in California and South Carolina, rapid delivery is assured for your critical network upgrades.
