The JBX03964 15-meter 100GBASE-SR4 QSFP28 active optical cable represents cutting-edge interconnect technology for enterprise and data center environments requiring high-bandwidth, reliable network connectivity. Engineered as a direct replacement for Fortinet FN-TRAN-QSFP28-15M original equipment, this AOC delivers exceptional performance in demanding applications. **Key Technical Features:** This multimode fiber optic cable utilizes OM3 50/125 fiber specification across 8 strands, enabling robust 100GB data rate transmission over the 15-meter span. The QSFP28 form factor ensures compatibility with modern high-density switch architectures while maintaining superior signal integrity. Active optical technology eliminates common copper cable limitations including electromagnetic interference, attenuation challenges, and thermal issues associated with electrical transmission. **Superior Build Quality:** The plastic jacketing with LSZH (low-smoke, zero-halogen) OFNR rating provides exceptional fire safety for building-code-compliant installations. This jacketing specification is particularly valuable in office towers, data centers, and critical infrastructure where fire safety regulations mandate flame-retardant cabling. The compact 12x12x15mm dimensions enable space-efficient routing through existing conduit and cable management systems. **Compliance & Certifications:** Full RoHS/ELV directive compliance (EU 2002/95/EC) and comprehensive safety certifications including UL, FDA 21CFR 1040.10, TUV, and Class 1 Laser designation ensure this cable meets the strictest international standards. IEEE 802.3bm qualification guarantees performance reliability and interoperability. **Operational Excellence:** With a 90-day limited warranty and support for custom brand programming, this solution adapts to enterprise requirements. The cable operates reliably across 0-70°C conditions, suitable for both climate-controlled data centers and variable industrial environments. **Ideal Applications:** Perfect for data center uplink connectivity, high-speed campus interconnects, and Fortinet network infrastructure modernization projects. The 15-meter length accommodates mid-range equipment separation while avoiding the cost and complexity of longer installations.
