The JBX05904 200GBASE-CR4 QSFP56 direct attach copper cable represents the pinnacle of high-speed data center connectivity solutions. Designed as a direct replacement for Arista's C-Q200-2Q100-2M component, this 2-meter passive breakout DAC cable eliminates the complexity and expense of active transceivers while delivering exceptional performance metrics. Key Technical Features: This 200GB-capable cable features a passive breakout design that splits 200GBASE-CR4 signals into dual QSFP56 connections, enabling flexible network architecture without additional equipment. The 26AWG twinax copper construction provides superior signal transmission characteristics, minimizing crosstalk and attenuation across the cable's length. With dimensions of 12x12x2mm, the cable integrates seamlessly into standard rack configurations. Performance & Compatibility: Qualified to IEEE 802.3cd and QSFP56 MSA specifications, this cable ensures plug-and-play compatibility with Arista networking infrastructure. The passive architecture eliminates power consumption concerns while maintaining the integrity of 200GB/s data transmission rates. The cable operates reliably across standard data center temperature ranges (0-70°C), accommodating diverse deployment scenarios. Compliance & Reliability: RoHS and ELV compliant, this cable meets EU directive 2002/95/EC environmental standards. Backed by safety certifications from TUV and UL, it undergoes rigorous testing for electrical safety and performance consistency. The 90-day limited warranty provides peace of mind for enterprise deployments. Applications & Use Cases: Ideal for high-capacity data center interconnects, cloud infrastructure expansions, and enterprise networking upgrades. The passive design makes it particularly suitable for cost-sensitive deployments where active solutions present unnecessary complexity. Network administrators appreciate the straightforward installation process and immediate operational readiness. Value Proposition: Compare this solution to active alternatives: lower cost, no power requirements, reduced heat generation, and simplified troubleshooting. The JBX05904 delivers enterprise-grade performance without premium pricing. Combined with free standard shipping on orders exceeding $99 and availability from multiple US distribution centers, procurement becomes both economical and convenient.
