The JBX05663 2-meter 100GBASE-CR4 QSFP28 breakout DAC cable represents a cost-effective, high-performance solution for modern data center infrastructure. Designed as a direct replacement for the Juniper JNP-100G-4X25G-2M, this passive breakout cable enables seamless integration into existing network architectures. **Key Features & Specifications:** This cable features a robust 30AWG twinax copper construction with plastic jacketing, providing optimal signal transmission over 2-meter distances. The passive design requires no external power, reducing operational costs and complexity compared to active alternatives. Supporting IEEE 802.3bj standards and QSFP28 MSA compliance, it delivers reliable 100GB connectivity across four 25GB SFP28 ports. **Technical Performance:** Operating across temperatures from 0°C to 70°C (32°F to 158°F), the cable maintains consistent performance in diverse environments. The copper connectors ensure durability and repeatability, while compliance with RoHS Directive 2002/95/EC and EU regulations guarantees environmental responsibility. **Ideal Applications:** Perfect for data center interconnects, server aggregation, and high-density switch deployments where short-reach connectivity is required. The breakout configuration enables efficient bandwidth scaling without requiring additional switch ports. **Compatibility & Quality Assurance:** Fully compatible with Juniper equipment and other standards-compliant systems. Backed by a 90-day limited warranty. Custom brand programming is available for enterprise requirements. Ships from multiple US locations (Danville, CA and Beaufort, SC) with free standard shipping on qualifying orders. **Compliance & Safety:** Certified under RoHS, TUV, and UL standards, ensuring the highest quality and safety benchmarks for professional networking installations.
