The JBX05173 5m Juniper-compatible 40GBASE-CR4 QSFP+ Direct Attach Copper breakout cable represents a superior networking solution for demanding data center environments. This passive breakout DAC cable provides four independent SFP+ connections from a single QSFP+ port, delivering exceptional flexibility and performance. **Technical Excellence:** Built with premium 26AWG twinax copper conductors, this cable maintains signal integrity over the full 5-meter span while adhering to IEEE 802.3ba specifications. The passive design eliminates power consumption concerns and associated heat generation, making it an energy-efficient choice for large-scale deployments. Operating across a 0-70°C temperature range, the cable performs reliably in various data center conditions. **Certified Quality & Compliance:** Fully compliant with RoHS, TUV, and UL safety certifications, this cable meets EU directive 2002/95/EC standards. These certifications ensure environmental responsibility and user safety across global installations. The cable is engineered to precise specifications as a direct replacement for Juniper's OEM part QFX-QSFP-DACBO-5M. **Practical Applications:** Ideally suited for interconnecting QFX switches to SFP+ enabled networking equipment, this breakout cable excels in: • High-density switch port aggregation • Multi-rack data center connectivity • Server-to-network interconnections • Low-latency, high-bandwidth applications **Value Proposition:** Passive DAC cables offer superior advantages over active alternatives: lower cost, no power requirements, minimal latency, and reduced operational complexity. The 5-meter length provides flexibility in medium-distance runs without signal degradation. **Durability & Support:** With robust plastic jacketing protecting the internal copper construction, this cable withstands typical data center installation demands. It includes a 90-day limited warranty and ships from U.S. locations with free standard shipping on qualifying orders. Custom brand programming is available for large deployments.
