The JBX03219 3-meter 400GBASE-SR8 QSFP-DD Active Optical Cable represents cutting-edge connectivity technology for next-generation data center architectures. As a direct Cisco QDD-4ZQ100G-AOC3M compatible solution, this breakout cable provides cost-effective flexibility without sacrificing performance or reliability. **Technical Specifications:** The cable utilizes 16 strands of OM3 50/125 multimode fiber configured to support 400GBASE-SR8 transmission standards. The QSFP-DD form factor consolidates four 100Gb channels into a single compact connector, while the breakout configuration expands to four discrete QSFP56 ports—ideal for network flexibility and future scalability. The 3-meter length optimizes mid-range interconnections typical in modern data center switch-to-switch and switch-to-server deployments. **Safety & Compliance:** Extensive certifications ensure maximum operational safety: Class 1 Laser product classification, UL/FDA 21CFR 1040.10 compliance, and TUV validation. The LSZH OFNR-rated jacket minimizes smoke and halogen emissions during potential fires, meeting building codes for critical infrastructure installations. RoHS/ELV directive compliance confirms environmental responsibility. **Performance Characteristics:** Operating temperature range of 0-70°C provides reliability across diverse data center cooling scenarios. IEEE 802.3cm and CMIS standard qualification ensures interoperability with enterprise-class equipment. Active optical technology eliminates signal degradation associated with passive copper alternatives, delivering superior performance for high-frequency 400GB applications. **Ideal Applications:** Perfect for hyperscale data centers, cloud computing facilities, financial trading systems, and research institutions requiring high-bandwidth, low-latency connectivity. The breakout configuration enables granular bandwidth management and simplified network upgrades. **Included Benefits:** - Free standard shipping on orders exceeding $99 - 90-day limited warranty protecting your investment - Manufactured to strict quality standards (VN, CN facilities) - Custom brand programming available for enterprise deployments This cable represents the optimal balance of performance, reliability, and value for organizations demanding 400GB network infrastructure.
