The JBX03499 Dell-compatible 40GBASE-SR4 QSFP+ active optical cable represents a superior alternative to standard copper connections for high-bandwidth data center applications. Manufactured to exacting standards in Vietnam and China, this 25-meter breakout AOC seamlessly replaces the original Dell part number 470-ABMP-25M while delivering exceptional reliability and performance. **Technical Specifications:** This cable features 8 strands of OM3 50/125 multimode fiber optimized for 40GB transmission over distances up to 25 meters. The QSFP+ form factor connects to a single 40GBASE-SR4 port and breaks out into four SFP+ connections, providing flexible topology options. The cable's LSZH (low-smoke zero-halogen) outer jacketing meets OFNR (Optical Fiber Non-Conductive Riser) ratings, making it compliant with NEC Article 770 for in-building installations. **Performance & Compatibility:** Fully IEEE 802.3ba qualified and supporting SFF-8436 specifications, this AOC delivers reliable 40GB Ethernet performance. The active optics eliminate traditional transceiver requirements, reducing overall system cost and complexity while improving signal integrity. Direct compatibility with Dell equipment ensures seamless integration into existing infrastructure. **Safety & Compliance:** Comprehensive certifications include Class 1 Laser safety, TUV, UL/FDA (21CFR 1040.10), and RoHS/ELV compliance. The cable operates safely within 0°C to 70°C environmental parameters and includes a 90-day limited warranty. **Ideal Applications:** Perfect for enterprise data centers, high-frequency trading environments, cloud computing facilities, and research institutions requiring short-reach, high-speed optical interconnections. The breakout configuration accommodates flexible port density requirements while maintaining superior signal quality compared to passive alternatives.
