The JBX03399 represents a professional-grade solution for enterprises requiring ultra-high-speed optical connectivity. As a 400GBASE-SR4 QSFP-DD active optical cable, it represents the cutting edge of short-reach, high-bandwidth data center networking technology. **Key Technical Features:** This 100-meter cable utilizes OM4 50/125 multimode fiber with 16 strands, delivering the bandwidth necessary for modern 400GB Ethernet standards. The active optical design incorporates integrated electronics that amplify and retransmit signals, enabling longer cable runs compared to passive solutions while maintaining signal integrity. The QSFP-DD form factor provides superior density in high-port-count switch environments. **Standards Compliance & Safety:** Fully qualified to IEEE 802.3db specifications and compliant with QSFP-DD MSA and CMIS standards, this cable integrates seamlessly into standardized network architectures. Comprehensive safety certifications including UL/FDA compliance (21CFR 1040.10), Class 1 laser rating, and TUV approval ensure safe deployment in any facility. RoHS and ELV directive compliance demonstrates environmental responsibility without sacrificing performance. **Construction & Durability:** The OFNR (Riser Rated) LSZH jacketing provides flame resistance and low-smoke characteristics essential for facility safety codes. Manufactured in Vietnam and China, this cable undergoes rigorous quality control. The robust plastic jacketing protects internal fiber strands from physical damage while maintaining flexibility for installation in tight spaces. **Applications & Compatibility:** Ideal for data centers, high-performance computing clusters, and enterprise networking infrastructure. Direct compatibility with Dell systems (replacing OEM part numbers 470-ADYR-100M, 470-BBGD-100M, 470-ADYW-100M, 470-BBGH-100M) simplifies procurement and deployment. The 100-meter length accommodates large facility layouts while the low-latency transmission enables real-time applications. **Operating Parameters:** Designed for reliable operation across standard temperature ranges (0-70°C), with 16 fiber strands ensuring redundancy and performance stability. Low power consumption compared to electronic alternatives reduces data center cooling requirements and energy costs. **Value Proposition:** This cable delivers enterprise-grade performance and reliability at competitive pricing with free standard shipping on qualifying orders. The 90-day limited warranty provides baseline protection, while custom brand programming availability offers solution flexibility for resellers and integrators.
