The JBX03902 50-meter 100GBASE-SR4 QSFP28 active optical cable represents a professional-grade solution for demanding data center and enterprise networking applications. As a direct replacement for HPE part number 845424-B21-50M, this breakout cable seamlessly integrates into existing infrastructures while providing superior performance and reliability. Key Features: This AOC cable leverages OM3 50/125 multimode fiber technology with 8 fiber strands, delivering 100GB data rates across distances up to 50 meters. The QSFP28-to-4x SFP28 configuration allows administrators to maximize port density and flexibility, converting a single high-speed port into four independent 25GB connections. The OFNR (Riser) rated jacket ensures fire safety compliance in vertical cable runs, while the plastic jacket protects fibers from environmental stress. Compliance & Safety: Fully qualified to IEEE 802.3bm and QSFP28 MSA specifications, this cable meets international safety standards including UL/FDA 21CFR 1040.10, TUV, and RoHS/ELV directives. Class 1 laser classification ensures safe operation in production environments. Operational Performance: With an operating temperature range of 0-70°C (32-158°F), this cable performs reliably in standard data center conditions. The 50-meter length accommodates medium-distance interconnects between equipment racks, switches, and storage arrays. Value & Support: Includes a 90-day limited warranty and qualifies for free standard shipping on orders over $99. Custom brand programming is available for OEM partners. Ships from strategically located U.S. warehouses in California and South Carolina for rapid delivery. Applications: Ideal for enterprise data centers, high-performance computing clusters, cloud infrastructure, and campus networks requiring 100GB connectivity with port expansion capabilities.
