The JBX03872 represents a cost-effective solution for organizations requiring HPE-compatible 100GB optical connectivity. This 25-meter Active Optical Cable (AOC) serves as a direct replacement for HPE part number 845424-B21-25M, providing seamless integration with existing HPE infrastructure without compatibility concerns. **Key Technical Features:** This QSFP28 to 4x SFP28 breakout architecture enables flexible port density expansion, converting a single 100GB QSFP28 interface into four 25GB SFP28 connections. The OM3 50/125 multimode fiber core supports the demanding 100GBASE-SR4 standard, qualified to IEEE 802.3bm specifications and QSFP28 MSA requirements. With 8 fiber strands providing redundancy and signal integrity, the cable maintains consistent performance across its 25-meter length. **Safety and Compliance:** Constructed with plastic jacketing and LSZH (Low Smoke Zero Halogen) material, this cable meets OFNR (Optical Fiber Non-conductive Riser) fire safety ratings. Multiple certifications including Class 1 Laser, TUV, UL/FDA 21CFR 1040.10, and RoHS compliance ensure safe operation in regulated environments. Operating range of 0-70°C (32-158°F) accommodates standard and elevated data center temperatures. **Ideal Applications:** Perfect for high-density data centers, enterprise network upgrades, server interconnects, and storage area networks (SANs) requiring HPE compatibility. The breakout configuration supports network virtualization and load balancing scenarios. **Shipping and Support:** Qualifies for free standard shipping on orders exceeding $99. Backed by 90-day limited warranty. Custom brand programming available upon request. Ships from strategically located U.S. facilities in California and South Carolina for expedited delivery.
