The JBX05082 1.5m 400GBASE-CR8 QSFP-DD to 8x SFP56 direct attach copper cable is an essential component for modern data center infrastructure requiring high-capacity, cost-effective connectivity solutions. This passive breakout cable transforms a single 400GB QSFP-DD port into eight individual 50GB SFP56 connections, making it ideal for network aggregation, switch fabric interconnects, and equipment upgrades. **Key Features & Benefits:** This direct attach copper (DAC) cable leverages passive technology, eliminating the need for active components, power consumption, and complex signal processing. The 30AWG twinax construction ensures superior signal integrity and reduced electromagnetic interference. Designed as a drop-in replacement for Juniper's QDD-8x50G-1P5M, it offers seamless compatibility with existing network deployments. **Technical Specifications:** Operating at 400GBASE-CR8 speeds, the cable meets ETC specifications and CMIS standards, ensuring reliable 400GB throughput. The 1.5-meter length accommodates typical rack and cabinet spacing while maintaining optimal signal quality. With a compact 12x12x2 form factor, it integrates cleanly into dense networking environments. **Certifications & Compliance:** Fully RoHS and ELV compliant, with TUV and UL safety certifications, this cable meets EU directive 2002/95/EC standards. The comprehensive compliance profile ensures deployment in regulated environments and enterprise networks. **Applications:** Ideal for data center networks, HPC clusters, cloud infrastructure, and carrier-grade telecommunications. Perfect for environments transitioning from 100GB to 400GB architectures or consolidating multiple 50GB connections. **Warranty & Support:** Backed by a 90-day limited warranty with free standard shipping on orders over $99. Custom brand programming available for OEM requirements.
