The JBX05199 represents a high-performance solution for enterprise-grade network infrastructure requiring 40GBASE-CR4 connectivity. This 1-meter active breakout direct attach copper cable is purpose-designed as a drop-in replacement for the Juniper JNP-QSFP-DACBO-1MA original equipment part number. **Technical Specifications:** This cable features a single QSFP+ connector on one end that intelligently breaks out into four individual SFP+ connectors, enabling simultaneous multi-port connectivity. The 30AWG copper construction ensures optimal signal integrity while maintaining industry-standard impedance matching. Operating within the 0-70°C temperature range, the cable delivers consistent performance in both standard and elevated thermal environments typical of data center operations. **Compliance & Certification:** Fully compliant with IEEE 802.3ba specifications and SFF-8436 standards, this cable meets stringent safety and environmental requirements. RoHS/ELV directive compliance ensures lead-free, environmentally responsible manufacturing. Additional certifications from TUV and UL validate electrical safety and performance reliability. **Performance Advantages:** Unlike optical transceivers, direct attach copper cables eliminate latency concerns while consuming significantly less power. The active design optimizes signal conditioning, supporting reliable 40Gbps transmission across the full 1-meter length. This makes the solution ideal for equipment racks, switch stacking, and interconnect applications. **Application Scenarios:** Perfect for data center upgrades, high-frequency trading environments, content delivery networks, and cloud infrastructure deployments. The Juniper compatibility ensures seamless integration with existing network architectures. **Shipping & Support:** Available with free standard shipping on qualifying orders, shipped from conveniently located U.S. warehouses in California and South Carolina. The 90-day limited warranty provides peace-of-mind protection. Custom brand programming is available for enterprise deployments.
