The JBX05236 Direct Attach Copper (DAC) cable represents a sophisticated solution for modern data center connectivity requirements. This 5-meter active breakout cable is specifically engineered to replace the Juniper JNP-QSFP-DACBO-5MA and QFX-QSFP-DACBO-5MA original equipment manufacturer part numbers, ensuring seamless compatibility with existing Juniper infrastructure. **Technical Specifications & Performance:** Operating at 40GBASE-CR4 standards, this cable delivers consistent 40GB data rates essential for demanding network applications. The 30AWG twinax copper construction minimizes signal degradation while providing exceptional durability. IEEE 802.3ba qualification ensures interoperability across certified network equipment, while SFF-8436 compliance maintains compatibility with QSFP+ standards. The cable's copper connectors provide superior conductivity compared to alternative materials, supporting reliable low-voltage network signal transmission. **Design & Construction:** Measuring 12x12x5 dimensions with a total length of 5 meters, this cable offers optimal spacing for standard data center rack configurations. The plastic jacketing provides protective insulation while maintaining flexibility for installation in confined spaces. The QSFP+ to 4x SFP+ breakout design enables single high-speed connections to be distributed across multiple lower-speed ports, maximizing equipment utilization efficiency. **Compliance & Certification:** Fully compliant with RoHS (EU Directive 2002/95/EC) and ELV regulations, this cable meets international environmental standards. TUL and UL safety certifications confirm adherence to electrical safety requirements, while the operating temperature range of 0-70°C accommodates diverse data center environments. Manufactured in Vietnam and China with stringent quality controls. **Practical Applications:** Ideal for cloud service providers, enterprise data centers, and network infrastructure modernization projects. The breakout configuration supports virtualization platforms requiring flexible port aggregation. Cost-effective alternative to fiber optics for short-distance intra-rack and inter-rack connections. Backed by 90-day limited warranty and available for custom brand programming to meet specific organizational requirements.
