The JBX05588 5m Juniper-compatible 100GBASE-CR4 QSFP28 to 4x SFP28 passive breakout DAC cable represents a strategic investment for modern data center and enterprise networking infrastructure. Engineered to replace Juniper's OEM JNP-100G-4X25G-5M cable, this solution delivers identical performance at competitive pricing while maintaining full compatibility with Juniper switching and routing equipment. **Product Overview** This passive breakout cable features a single QSFP28 connector that splits into four discrete SFP28 ports, enabling a 100GB connection to be distributed across four 25GB channels. The 5-meter length provides optimal flexibility for mid-range rack connectivity and equipment placement in data center environments without signal degradation. **Technical Specifications** Manufactured with 26AWG copper conductors and protective plastic jacketing, the cable delivers superior signal integrity for high-speed data transmission. The construction is RoHS and ELV compliant, meeting EU Directive 2002/95/EC requirements. Multiple safety certifications including TUV and UL validation ensure operator and equipment safety in diverse installation environments. The cable is qualified to IEEE 802.3bj specifications, QSFP28 MSA standards, and SFF-8665 form factor requirements, guaranteeing seamless interoperability with industry-standard network equipment beyond Juniper platforms. **Performance & Applications** Operating across temperatures from 0°C to 70°C (32°F to 158°F), this cable maintains consistent performance in various data center conditions. The passive architecture eliminates external power requirements and active cooling necessities, reducing operational complexity and associated costs. Ideal applications include: - Data center network aggregation and spine-leaf architectures - High-performance computing cluster interconnects - Storage area network (SAN) implementations - Enterprise campus backbone upgrades - 400G equipment downlinks with 100G terminal ports **Advantages of Passive Breakout DAC** Unlike active cables and transceiver-based solutions, this passive DAC offers lower latency, superior power efficiency, and reduced heat generation. Without active components, reliability improves while total cost of ownership decreases significantly. **Shipping & Support** Shipped from convenient US locations in Danville, CA and Beaufort, SC, this cable qualifies for free standard shipping on orders exceeding $99. The 90-day limited warranty provides peace of mind and customer protection. Custom brand programming availability accommodates organizations with specific labeling or branding requirements. The JBX05588 delivers professional-grade performance, full Juniper equipment compatibility, and exceptional value for network infrastructure modernization projects.
