The JBX05584 5m 100GBASE-CR4 QSFP28 to 4x SFP28 Direct Attach Copper (DAC) Fortinet-compatible breakout cable delivers exceptional performance for high-speed network deployments. This passive breakout solution provides an economical alternative to active breakout cables, eliminating power consumption requirements while maintaining maximum throughput and minimal latency. **Key Features and Benefits:** This premium twinax copper DAC cable features 26AWG gauge conductors optimized for 100GB signal transmission. The passive breakout design converts a single QSFP28 100GB connection into four independent SFP28 25GB channels, enabling flexible network architecture scaling. Fully compatible with Fortinet equipment, it serves as a direct replacement for part number FN-CABLE-QSFP28-4SFP28-5. **Technical Excellence:** Qualified to IEEE 802.3bj specifications and QSFP28 Multi-Source Agreement standards, this cable guarantees interoperability with enterprise networking infrastructure. Copper connectors provide superior signal integrity and durability compared to optical alternatives. The 5-meter length accommodates mid-range rack-to-rack and switch-to-chassis connectivity typical in modern data center environments. **Compliance and Reliability:** Extensive certifications including RoHS, TUV, and UL compliance ensure safe deployment in regulated environments. Built to EU Directive 2002/95/EC standards, it meets environmental and safety requirements across global markets. Operating temperature range of 0-70°C supports both controlled data center conditions and diverse deployment scenarios. **Value Proposition:** Compared to active breakout cables, this passive solution reduces operational costs while maintaining performance. The 90-day limited warranty provides purchase protection, backed by convenient shipping from multiple U.S. locations (Danville, CA and Beaufort, SC). Custom brand programming is available for enterprise deployments requiring specific identification or integration requirements. **Ideal Applications:** Perfect for enterprise data centers, service providers, and telecommunications facilities requiring high-density 100GB to 25GB migration paths, switch aggregation, and flexible network scaling without compromising performance or reliability.
