The JBX05228 3-meter QSFP+ to 4x SFP+ Direct Attach Copper (DAC) breakout cable represents a cost-effective, high-performance solution for modern data center networking requirements. This passive cable is specifically engineered as a compatible replacement for HPE's JG330A, delivering identical performance specifications and reliability. **Technical Specifications:** This cable supports 40GBASE-CR4 speeds with full compliance to IEEE 802.3ba standards. The 30AWG gauge copper conductors provide optimal signal integrity while maintaining flexibility for installation in tight rack environments. Measuring 3 meters in length with compact dimensions (12x12x3), the cable fits seamlessly into existing network infrastructures. **Performance & Reliability:** As a passive breakout DAC, the JBX05228 requires no active components or external power, eliminating potential points of failure and reducing total cost of ownership. The RoHS and EU 2002/95/EC certified construction ensures compliance with international environmental standards. Safety certifications from TUV and UL verify adherence to stringent electrical safety requirements. Operating temperature range of 0-70°C (32-158°F) accommodates standard data center conditions. **Compatibility & Application:** Fully compatible with HPE and H3C networking equipment, this cable seamlessly integrates into existing enterprise environments. The QSFP+ connector to 4x SFP+ breakout configuration enables flexible network topology scaling, allowing organizations to convert single high-speed ports into multiple standard connections without expensive switching equipment upgrades. **Value Proposition:** Backrd by a 90-day limited warranty and manufactured in Vietnam and China using proven production processes, this cable delivers enterprise-grade reliability at competitive pricing. Custom brand programming is available for organizations requiring OEM labeling. Free standard shipping on orders exceeding $99 makes this an economical choice for bulk network upgrades. **Use Cases:** Ideal for data center migrations, storage area network (SAN) expansions, and high-performance computing cluster deployments. Organizations modernizing aging 10GB infrastructure to 40GB connectivity will find this breakout cable essential for cost-effective infrastructure evolution without complete equipment replacement.
