The JBX05608 3-meter 100GBASE-CR4 QSFP28 to SFP28 breakout DAC is a professional-grade networking component designed for modern data center architectures. As a direct replacement for NVIDIA Mellanox part numbers MCP7F00-A003, MCP7F00-A003R30L, 980-9I48G-00C003, and 980-9I48H-00C003, this cable ensures compatibility with existing Mellanox infrastructure without compatibility concerns. Key Features and Specifications: This passive direct attach cable utilizes premium 28AWG copper conductors with a protective plastic jacket, delivering 100Gbps performance over a 3-meter distance. The single QSFP28 connector breakout design provides four SFP28 ports, enabling flexible network topology configurations. The cable's passive architecture requires no external power, reducing power consumption and cooling requirements in dense server environments. Technical Excellence: Fully qualified to IEEE 802.3bj and QSFP28 MSA standards, the JBX05608 meets rigorous signal integrity requirements. It operates reliably across 0-70°C (32-158°F), accommodating various data center thermal conditions. The RoHS and ELV compliance ensures environmental responsibility and regulatory adherence across global markets. TUV and UL certifications provide additional assurance of safety and reliability. Applications and Use Cases: Ideal for high-speed data center networking, this breakout DAC is perfect for connecting servers, switches, and storage systems in 100Gbps network environments. It's particularly valuable for applications requiring flexible port configurations without dedicated breakout switches. The 3-meter length provides versatility for various rack layouts and system arrangements. Advantages Over Alternatives: Compared to active breakout cables, the passive design reduces power consumption and heat generation. Direct attach technology eliminates transceiver costs while delivering superior latency characteristics compared to optical solutions. The NVIDIA Mellanox compatibility ensures seamless integration with enterprise-grade infrastructure.
