The JBX03184 10-meter 400GBASE-SR4.2 QSFP-DD to 4x QSFP28 active optical breakout cable represents cutting-edge fiber optic technology designed for modern high-density data center deployments. This premium interconnect solution enables seamless integration between 400G-capable network infrastructure and existing QSFP28 equipment, maximizing your technology investment while supporting exponential bandwidth growth. **Key Technical Specifications:** This AOC features 16 strands of OM3 50/125 multimode fiber optimized for 400Gbps transmission over 10 meters. The active optical design incorporates integrated electronics for signal conversion, eliminating the need for separate optics and transceiver modules. IEEE 802.3bs and QSFP-DD MSA qualification ensures interoperability across vendor ecosystems. **Superior Safety and Compliance:** The OFNR (riser-rated) flame-retardant LSZH jacket meets stringent building codes for vertical installations and plenum applications. Comprehensive safety certifications including UL/FDA 21CFR 1040.10, TUV, and Class 1 Laser compliance demonstrate adherence to the highest industry standards. Full RoHS/ELV compliance aligns with environmental regulations across all major markets. **Deployment Advantages:** Breakout AOCs like the JBX03184 offer significant advantages over traditional 400G solutions. They reduce equipment complexity by converting single 400G lanes into four 100G connections, enabling flexible network architecture without costly equipment replacements. The 10-meter length accommodates typical data center row spacing while maintaining signal integrity. **Ideal Use Cases:** Perfect for upgrading existing Cisco infrastructure to 400G capabilities, this cable excels in spine-leaf architectures, core network segments, and high-performance computing environments. The Cisco QDD-4X100G-AOC10M direct compatibility ensures hassle-free installation. **Operational Reliability:** With extended operating temperature range (0-70°C) and robust plastic jacketing with 12x12x10mm dimensions, this cable withstands demanding data center conditions. The 90-day limited warranty provides peace of mind on your networking investment. **Value Proposition:** Offering free standard shipping on orders exceeding $99, with manufacturing facilities in Vietnam and China ensuring competitive pricing without compromising quality. This is an essential component for organizations standardizing on 400G infrastructure while maintaining backward compatibility with existing 100G deployments.
