The JBX04959 200GBASE-CR8 QSFP-DD to 2x QSFP28 Direct Attach Copper (DAC) Breakout Cable represents a critical infrastructure component for modern high-speed networking environments. Specifically engineered to complement Juniper network architectures, this 2.5-meter cable bridges the gap between 200Gbps QSFP-DD ports and dual 100Gbps QSFP28 connections, providing unparalleled flexibility in port density and bandwidth management. **Technical Specifications & Performance:** This passive breakout DAC utilizes 28AWG copper twinax construction, delivering exceptional signal fidelity without requiring external power or active components. The 200GBASE-CR8 standard ensures full compatibility with modern 200Gbps applications while maintaining backward compatibility considerations. Operating reliably across 0°C to 70°C temperature ranges, the cable suits both controlled data center environments and edge deployment scenarios. **Compliance & Safety:** Comprehensive regulatory certifications including RoHS (2002/95/EC), TUV, and UL approval guarantee compliance with international standards. These certifications affirm the cable's environmental responsibility and safety performance, making it suitable for enterprises with stringent procurement requirements. **Juniper Ecosystem Integration:** As a certified direct replacement for Juniper's QDD-2X100G-2P5M part number, this cable integrates seamlessly with Juniper MX, PTX, and QFX platforms. The QSFP-DD form factor ensures proper mechanical engagement and electrical performance across compatible Juniper switching hardware. **Practical Applications:** Ideal for data center interconnects, storage area networks (SANs), and high-performance computing (HPC) clusters, this breakout cable maximizes port utilization on 200G-capable hardware. IT professionals leverage these cables to cost-effectively expand network capacity without upgrading entire switching infrastructure. **Quality Assurance:** Manufactured in Vietnam and China with stringent quality controls, each cable includes a 90-day limited warranty. Ships from conveniently located US distribution centers (Danville, CA and Beaufort, SC) with free standard shipping on orders exceeding $99, ensuring rapid deployment timelines. **Custom Options Available:** Custom brand programming is available for organizations requiring OEM labeling or specific branding requirements, supporting volume deployments and white-label reseller opportunities.
