The JBX05426 2.5m 40GBASE-CR4 QSFP+ Passive Direct Attach Copper Cable represents a critical infrastructure component for modern high-speed networking environments. Specifically designed for Palo Alto Networks compatibility, this cable delivers enterprise-grade performance at a competitive price point. Technical Specifications: This 30AWG twinax copper cable features QSFP+ connectors on both ends, enabling 40Gbps data transmission over distances up to 2.5 meters. The passive DAC design eliminates the need for external power, reducing complexity and heat generation in server racks and network switches. Manufactured to IEEE 802.3ba specifications, the cable ensures compatibility across diverse networking equipment while maintaining signal integrity and low latency characteristics essential for bandwidth-intensive applications. Compliance and Certification: The cable meets stringent RoHS and ELV directives, with TUV and UL certifications validating safety and quality standards. These certifications ensure compatibility with regulated environments including healthcare facilities, financial institutions, and government agencies requiring certified network infrastructure. Applications and Use Cases: Ideal for data center switching fabrics, server-to-switch interconnects, and storage area network (SAN) implementations. The 2.5-meter length accommodates standard rack configurations while maintaining optimal signal quality. Organizations utilizing Palo Alto Networks firewalls, switches, and interconnect systems will appreciate the certified compatibility and drop-in replacement capability. Advantages Over Alternatives: Unlike active cables, passive DAC technology provides superior reliability with zero power consumption and extended lifespan. Compared to fiber optic solutions, copper DAC cables offer lower total cost of ownership and simpler installation procedures, making them the preferred choice for short-reach, high-bandwidth networking requirements. Warranty and Support: Backed by a 90-day limited warranty, this cable includes free standard shipping on orders exceeding $99, with availability from strategically located distribution centers in Danville, CA and Beaufort, SC for rapid deployment. The product ships ready for immediate integration into existing network infrastructure, with custom brand programming available for OEM requirements.
