The JBX03228 7-meter 400GBASE-SR8 QSFP-DD Active Optical Cable represents the cutting edge of data center connectivity solutions. Designed as a direct replacement for Cisco's QDD-4ZQ100G-AOC7M, this breakout AOC provides exceptional performance for high-density switch deployments and cloud infrastructure environments. **Performance & Specifications:** This cable delivers 400GB aggregate throughput by aggregating four 100GB QSFP56 connections through a single QSFP-DD interface. The 16-strand OM3 multimode fiber core (50/125 microns) ensures optimal signal transmission over the 7-meter distance, ideal for intra-rack and inter-rack connections in modern data centers. Compliance with IEEE 802.3cm specifications guarantees interoperability with certified networking equipment. **Safety & Compliance:** Comprehensive safety certifications include Class 1 Laser safety, TUV certification, UL/FDA 21CFR 1040.10 compliance, and EU RoHS/ELV directive adherence. The OFNR (Riser Rated) LSZH jacketing minimizes smoke and toxic fumes during unlikely fire scenarios, meeting building codes for vertical cable runs. **Construction & Durability:** The cable features durable plastic jacketing with embedded fiber strands, providing mechanical protection while maintaining the flexibility required for installation in constrained data center environments. Dimensions of 12x12x7 mm ensure compatibility with standard cable management systems. **Environmental Performance:** Operating temperature range of 0-70°C (32-158°F) supports diverse data center climates. The multimode fiber technology is ideal for shorter-distance, higher-bandwidth applications typical of modern 400G deployments. **Value & Support:** Enjoy free standard shipping on orders over $99, with product sourced from reliable manufacturing partners in Vietnam and China. The 90-day limited warranty provides peace of mind for critical infrastructure investments. Custom brand programming is available for OEM and enterprise customers requiring white-label solutions. **Applications:** Perfect for enterprise data centers, cloud providers, financial institutions, and large-scale computing environments requiring high-density 400G connectivity. The breakout configuration enables cost-effective network expansion without requiring additional high-end switch ports.
