The JBX05561 100GBASE-CR4 QSFP28 Direct Attach Copper (DAC) breakout cable represents an ideal solution for organizations seeking cost-effective, high-speed data center connectivity. This 2-meter passive breakout cable is a direct, compatible replacement for Juniper's OEM part number JNP-100G-2X50G-2M, offering identical performance at a fraction of the cost. Key Features and Specifications: This cable utilizes premium 30AWG twinax copper construction with QSFP28 connectors on both ends, designed to split one 100GBASE-CR4 connection into two 50GB channels. The passive design eliminates the need for active electronics, powering, or cooling—reducing operational complexity and total cost of ownership. Each connector features gold-plated copper contacts ensuring superior conductivity and longevity. Technical Excellence: The JBX05561 is fully qualified to IEEE 802.3bj specifications and meets QSFP28 MSA and SFF-8665 standards. With RoHS, TUV, and UL safety certifications, this cable meets stringent environmental and safety requirements, including EU directive 2002/95/EC compliance. The robust plastic jacketing protects internal conductors while maintaining flexibility for installation in confined spaces. Applications and Use Cases: Ideal for data center networking, high-performance computing environments, and enterprise switch interconnections. This breakout DAC cable excels in scenarios requiring cost-effective 100GB-to-50GB connectivity without introducing additional latency or signal degradation. Perfect for organizations upgrading infrastructure or optimizing network density. Reliability and Support: Operating across a wide temperature range (0-70°C / 32-158°F), this cable delivers consistent performance in various environments. Backed by a 90-day limited warranty and available with custom brand programming options, the JBX05561 provides enterprise-grade reliability with exceptional value.
