The JBX03859 represents a high-performance solution for modern data center connectivity, specifically engineered as a direct replacement for NVIDIA Mellanox MFA7A50-C001 active optical cables. This 1-meter 100GBASE-SR4 QSFP28-to-4x SFP28 breakout cable delivers the speed and reliability enterprises demand for their most critical network infrastructure. **Technical Specifications & Performance:** Built on OM3 50/125 multimode fiber with 8 strands, this AOC (Active Optical Cable) achieves 100GB data rates while maintaining signal integrity across full 1-meter length. The cable meets or exceeds IEEE 802.3bm standards and QSFP28 MSA specifications, ensuring seamless compatibility with NVIDIA Mellanox platforms and certified network equipment. **Safety & Compliance:** The LSZH (Low Smoke Zero Halogen) OFNR (Optical Fiber Non-conductive Riser) jacket provides superior fire safety and environmental protection, meeting EU directive 2002/95/EC (RoHS) and ELV standards. Class 1 laser certification with TUV and UL/FDA 21CFR 1040.10 approvals guarantees safe operation in enterprise environments. **Design & Durability:** Riser-rated construction enables installation in vertical cable runs and plenum spaces, while plastic jacketing with reinforced fiber strands provides mechanical protection and long-term reliability. Operating temperature range of 0-70°C (32-158°F) accommodates diverse data center environments. **Applications:** Ideal for high-speed interconnects in data centers, cloud computing facilities, HPC clusters, and enterprise networks. The 4-to-1 breakout configuration maximizes port utilization while reducing cable complexity. Backed by a 90-day limited warranty and supported by custom brand programming options for OEM and system integrators.
