The JBX05953 1-meter 200GBASE-CR4 QSFP56 to SFP56 direct attach copper cable represents a professional-grade networking solution for high-performance data centers and enterprise environments. As a direct replacement for the Cisco QSFP-4S50-CU1.5M, this passive breakout DAC provides exceptional value for organizations requiring reliable 200GB connectivity without premium active cable pricing. **Technical Excellence** Built with 30AWG twinax copper conductors and precision plastic jacketing, this cable delivers the low-latency, high-bandwidth characteristics essential for modern data center operations. The passive design eliminates signal regeneration delays found in active cables, making it ideal for latency-sensitive applications like high-frequency trading, real-time analytics, and video streaming infrastructure. **Compliance and Certification** Fully certified to IEEE 802.3cd specifications and qualified under QSFP56 MSA and CMIS standards, the JBX05953 meets stringent industry requirements. RoHS, TUV, and UL certifications ensure environmental responsibility and workplace safety compliance across global markets. EU directive 2002/95/EC compatibility confirms adherence to European hazardous substance restrictions. **Optimal Performance Range** Designed for operating temperatures from 0 to 70°C (32 to 158°F), this cable performs reliably in standard data center environments and moderately warm deployments. The 1-meter length provides flexibility for direct-attached configurations while maintaining signal quality. **Cisco Ecosystem Integration** Seamlessly compatible with Cisco infrastructure, the JBX05953 integrates effortlessly into existing deployments. The QSFP56 to 4x SFP56 breakout architecture enables versatile topology configurations, allowing single high-speed connections to split into multiple lower-speed lanes for mixed-speed network designs. **Enterprise-Grade Support** Backed by a 90-day limited warranty and available from domestic US locations (Danville, CA and Beaufort, SC), this cable ensures rapid replacement and minimal network downtime. Free standard shipping on orders exceeding $99 reduces total cost of ownership for bulk networking projects. **Application Scenarios** Ideal for server-to-switch direct connections, east-west data center traffic, storage area networks, and high-density interconnect applications. Cost-effective alternative to active cables in space-constrained environments or when power budget limitations require passive solutions.
