The JBX03556 represents professional-grade optical connectivity engineered for modern enterprise and data center infrastructure. As a 40GBASE-SR4 compliant QSFP+ to 4x SFP+ active optical breakout cable, it delivers the performance and reliability demanded by high-speed network environments. **Technical Excellence** This 7-meter cable utilizes OM3 50/125 multimode fiber with 8 individual fiber strands, meeting IEEE 802.3ba specifications for 40 Gigabit Ethernet short reach (SR4) applications. The active optical architecture incorporates integrated optical-to-electrical conversion, eliminating the need for separate optical modules and reducing system complexity. Operating across the temperature range of 0 to 70°C (32 to 158°F), the cable maintains optimal performance in diverse installation scenarios. **Safety and Compliance** The LSZH (Low Smoke Zero Halogen) jacketing and OFNR (Optical Fiber Non-Conductive Riser) rating provide superior fire safety characteristics, making this cable ideal for installations in occupied spaces, plenum areas, and regulated environments. Multiple certifications—including Class 1 Laser, TUV, UL, and FDA compliance—validate the cable's safety standards. Full RoHS and ELV directive compliance ensures environmental responsibility without compromising performance. **Practical Advantages** The breakout configuration provides significant installation flexibility, allowing system designers to transition from high-density QSFP+ aggregation to individual SFP+ port-level management. This architecture supports growth and scalability in network upgrades, making it ideal for migration scenarios and heterogeneous equipment environments. The 7-meter length accommodates moderate-distance runs typical in data center interconnects and equipment racks. **Reliability and Support** Cisco compatibility ensures seamless integration with existing infrastructure. The cable is backed by a 90-day limited warranty, and custom brand programming options are available for large deployments. Ships from US distribution centers with free standard shipping on orders exceeding $99, reducing lead times and total acquisition costs. **Applications** Ideal for 40Gb/s network deployments including data center upgrades, high-speed server interconnects, storage area networks, and enterprise backbone implementations where cost-effective optical breakout solutions are required.
