The JBX05392 40GBASE-CR4 QSFP+ passive direct attach cable is a professional networking solution designed for high-speed data center and enterprise applications. This 1-meter cable features premium copper construction with 30AWG twinax design, delivering reliable 40GB per second data transmission without compromising signal integrity or introducing latency. Key Technical Features: This cable is fully compatible with HPE Aruba switching infrastructure and serves as a direct replacement for HPE part number JH697A. The QSFP+ to QSFP+ connectors ensure seamless integration with existing equipment. The passive DAC (direct attach copper) architecture eliminates the need for active electronics, reducing power consumption and heat generation—critical advantages in energy-conscious data centers. Compliance & Certification: The cable meets stringent industry standards including IEEE 802.3ba and SFF-8436 specifications. It carries RoHS, TUV, and UL certifications, ensuring compliance with environmental regulations (EU Directive 2002/95/EC) and safety requirements. This makes it suitable for both regulated industries and environmentally conscious organizations. Ideal Applications: Perfect for high-density server racks, storage area networks (SAN), and campus backbone connections requiring short-reach, high-bandwidth connectivity. The 1-meter length is optimal for top-of-rack (ToR) switching scenarios and equipment-to-equipment connections within confined spaces. Operational Reliability: With an operating temperature range of 0-70°C (32-158°F), this cable performs reliably in various data center environments. The robust plastic jacketing protects against abrasion and environmental stress, while the 30AWG copper provides optimal impedance characteristics for 40GBASE-CR4 performance. Warranty & Support: Backed by a 90-day limited warranty. Ships from multiple US locations (Danville, CA and Beaufort, SC) with free standard shipping on orders exceeding $99. Custom brand programming is available for enterprise procurement requirements. Value Proposition: By choosing the JBX05392, you gain enterprise-grade connectivity at competitive pricing without sacrificing quality or reliability. The passive design ensures longevity and reduces total cost of ownership compared to active alternatives.
