The JBX05715 100GBASE-CR4 QSFP28 Passive Direct Attach Copper Cable represents a cost-effective, reliable solution for enterprise and data center networking environments requiring high-speed 100GB connectivity. With a 5-meter length, this cable is optimized for short-reach connections between switches, servers, and storage systems within modern network architectures. **Technical Specifications:** This passive DAC cable features QSFP28-to-QSFP28 connectors, delivering 100GB data rates while maintaining IEEE 802.3bj compliance. The 26AWG twinax copper construction ensures optimal signal integrity and minimal attenuation over its 5-meter span. The cable operates reliably across temperatures from 0°C to 70°C (32°F to 158°F), making it suitable for standard data center environments. **Compatibility & Performance:** Designed specifically for Juniper networks, this cable serves as a direct replacement for Juniper part numbers QFX-QSFP28-DAC-5M and JNP-100G-DAC-5M. The passive design eliminates the need for external power, reducing complexity and potential points of failure while delivering consistent, low-latency transmission. **Standards & Compliance:** The cable meets stringent international standards including IEEE 802.3bj, QSFP28 MSA, and SFF-8665 specifications. It carries RoHS, TUV, and UL certifications, ensuring compliance with EU directive 2002/95/EC for hazardous substances reduction. Custom brand programming is available for OEM requirements. **Advantages Over Alternatives:** Unlike active cables requiring power supply, passive DAC cables like the JBX05715 offer inherent reliability, reduced maintenance overhead, and lower total cost of ownership. The twinax copper construction provides excellent shielding against electromagnetic interference, critical in high-density server environments. **Applications:** Ideal for data center operators, network engineers, and IT professionals managing enterprise infrastructure. Perfect for top-of-rack to end-of-row connections, storage area network (SAN) deployments, and high-performance computing clusters requiring affordable, proven connectivity. **Shipping & Support:** Ships from multiple locations (Danville, CA and Beaufort, SC) with free standard shipping on orders exceeding $99. Backed by a 90-day limited warranty, ensuring customer satisfaction and peace of mind.
