The JBX03811 20-meter 100GBASE-SR4 QSFP28 active optical breakout cable represents cutting-edge connectivity technology for demanding data center and enterprise network environments. As a direct compatible replacement for NVIDIA Mellanox part numbers MFA7A20-C020 and 980-9I40K-00C020, this cable delivers seamless integration into existing infrastructure without compatibility concerns. **Technical Specifications & Performance:** This breakout AOC features dual QSFP28 termination with 8-strand OM3 50/125 multimode fiber core, enabling simultaneous 100GB transmission across breakout ports. The 20-meter length accommodates substantial intra-data center distances while maintaining the optical signal quality necessary for error-free operation. IEEE 802.3bm certification ensures compliance with industry standards for 100GBASE-SR4 transmission protocols. **Safety, Compliance & Environmental Standards:** Fully RoHS and ELV compliant, this cable meets EU Directive 2002/95/EC environmental regulations. The OFNR (Riser Rated) LSZH jacketing provides flame resistance rated to UL standards, while Class 1 Laser certification (per LN #50 7/2001) and FDA 21CFR 1040.10 compliance guarantee safe optical transmission. TUV certification further validates construction quality and safety protocols. **Durability & Reliability:** The 12x12x20mm form factor provides flexible routing through existing cable management infrastructure. Plastic jacketing combined with fiber strands creates a robust cable resistant to environmental stress, thermal fluctuation, and physical damage. Operating temperature range of 0 to 70°C (32 to 158°F) accommodates both air-conditioned data centers and hot-aisle environments. **Application & Compatibility:** Ideal for NVIDIA Mellanox switching environments, this cable enables 100GB interconnects between network nodes with minimal latency. The breakout configuration supports disaggregated network designs where dual-port connectivity enhances scalability and redundancy. Perfect for virtualization platforms, cloud infrastructure, high-performance computing clusters, and enterprise storage networks requiring multi-gigabit throughput. **Warranty & Support:** Backed by a comprehensive 90-day limited warranty with expedited shipping from Danville, CA and Beaufort, SC facilities. Custom brand programming is available for enterprise deployments. Free standard shipping on orders exceeding $99 provides exceptional value for network infrastructure investments.
