The JBX05803 100GBASE-CR4 QSFP28 passive direct attach copper cable represents an excellent solution for organizations seeking cost-effective, high-speed connectivity in their Juniper-based data center infrastructure. This 3-meter cable delivers exceptional performance and reliability for mission-critical networking applications. Technical Specifications & Performance: This cable features 28AWG twinax copper construction, enabling 100GB/s data transmission over distances up to 3 meters. The QSFP28 to QSFP28 connector configuration provides seamless integration with compatible Juniper network equipment. Operating within a temperature range of 0-70°C (32-158°F), the cable maintains consistent performance in various data center environments. Compliance & Certification: The JBX05803 is rigorously qualified to IEEE 802.3bj specifications and complies with global standards including RoHS (EU directive 2002/95/EC), TUV, and UL certifications. This ensures environmental responsibility and safety across international deployments. Advantages of Passive DAC Technology: Unlike active solutions, passive direct attach cables require no power, reducing complexity and operational costs. They generate minimal heat, contributing to improved data center energy efficiency. The passive design also eliminates potential points of failure associated with active components, enhancing overall system reliability. Applications & Use Cases: Ideal for connecting Juniper switches to storage arrays, servers, and other network infrastructure. Perfect for campus area networks (CANs), data center core connections, and high-density switching environments. The 3-meter length accommodates typical rack-to-rack installations and near-distance equipment connectivity. Compatibility & Replacement: This cable directly replaces Juniper part numbers QFX-QSFP28-DAC-3M and JNP-100G-DAC-3M, ensuring straightforward upgrades and inventory flexibility. Custom brand programming is available for organizations with specific labeling requirements. Reliability & Support: Backed by a 90-day limited warranty and shipped from strategically located U.S. facilities (Danville, CA and Beaufort, SC), this cable offers peace of mind and rapid delivery. Free standard shipping applies to orders exceeding $99, providing additional value for bulk purchases and enterprise deployments.
