The JBX03359 50-meter 400GBASE-SR8 QSFP-DD Active Optical Cable represents the industry standard for high-speed, long-distance optical connectivity in enterprise data centers and telecommunications infrastructure. This Dell-compatible solution delivers uncompromising performance for organizations requiring 400GB network speeds with extended cable runs. **Technical Specifications:** This active optical cable features 16 fiber strands of OM3 50/125 multimode fiber, optimized for short-range, high-bandwidth applications. Operating across a temperature range of 0-70°C (32-158°F), the cable maintains consistent performance in diverse environmental conditions. The QSFP-DD form factor provides industry-standard connectivity while the compact 12x12x50mm dimensions ensure easy installation in congested rack environments. **Compliance & Safety:** Full compliance with IEEE 802.3cm standards and QSFP-DD MSA specifications guarantees interoperability with certified equipment. Class 1 Laser certification, TUV validation, and UL/FDA approval (21CFR 1040.10) confirm safe operation in all deployment scenarios. RoHS and ELV directives compliance ensures environmental responsibility and future regulatory adherence. **Jacketing & Installation:** The LSZH (low-smoke zero-halogen) riser-rated OFNR jacketing provides superior fire safety characteristics, making this cable suitable for installation in plenum and non-plenum areas within buildings. The durable plastic jacketing protects fiber integrity while maintaining flexibility for routing through complex infrastructure. **Compatibility & Replacement:** Dell part numbers 470-ACTG-50M and 470-ACTY-50M are directly replaced by this cost-effective solution. The cable integrates seamlessly with Dell systems while maintaining compatibility with standard 400GBASE-SR8 QSFP-DD interfaces across multiple vendors. **Warranty & Support:** Backed by a 90-day limited warranty, this cable includes custom brand programming availability for enterprise deployments. Free standard shipping on orders exceeding $99 and convenient shipping locations in Danville, CA and Beaufort, SC ensure rapid delivery. **Applications:** Ideal for data center interconnects, high-performance computing clusters, financial trading floors, media processing facilities, and enterprise campus networks requiring maximum throughput with optical fiber reliability.
