The JBX05419 2.5-meter 40GBASE-CR4 QSFP+ Passive Direct Attach Copper Cable represents a premium networking solution for organizations requiring high-speed, reliable data transmission in enterprise and data center environments. Technical Excellence: This cable adheres to IEEE 802.3ba standards and delivers consistent 40Gbps performance with QSFP+ connectivity. The 30AWG twinax copper construction provides optimal signal integrity while minimizing electromagnetic interference. Unlike active DAC cables, the passive design eliminates power consumption and associated cooling requirements, reducing total cost of ownership. Design & Construction: The cable features robust plastic jacketing that protects against physical damage and environmental stress. At 2.5 meters, it provides ideal reach for most data center layouts without introducing signal degradation. The QSFP+ connectors (12x12mm form factor) are precision-engineered for secure, reliable connections and support hot-swappable operation. Compatibility & Standards: Manufactured to work seamlessly with Intel-compatible networking equipment, this cable replaces OEM part XLDACBL250CM. It meets RoHS and EU directive 2002/95/EC environmental compliance standards, ensuring safe operation and proper end-of-life recycling. TUV and UL safety certifications guarantee reliable performance across diverse deployment scenarios. Operating Specifications: • Temperature Range: 0-70°C (32-158°F) • Data Rate: 40GB • Form Factor: QSFP+ • Standards: IEEE 802.3ba, SFF-8436 • Warranty: 90-Day Limited Warranty Applications: Ideal for data center interconnects, high-frequency trading environments, video content delivery networks, and enterprise storage area networks (SANs). The 2.5m length accommodates typical server-to-switch and switch-to-switch topologies without excess cabling. Value Proposition: This passive DAC cable delivers enterprise-grade performance at competitive pricing. Fast shipping from Danville, CA or Beaufort, SC locations, plus free standard shipping on orders exceeding $99, ensures quick deployment. The 90-day warranty provides confidence in product reliability and customer support.
