The JBX03655 25-meter Cisco-compatible 40GBASE-AOC QSFP+ active optical cable represents the pinnacle of enterprise-grade network connectivity. Designed specifically for high-speed data transmission in demanding environments, this active optical cable combines cutting-edge fiber technology with proven Cisco compatibility. ## Technical Specifications This cable features an 8-strand fiber construction using OM3 50/125 multimode fiber, the industry standard for 40GB applications. The active optical technology eliminates signal degradation over longer distances, making this 25-meter cable ideal for sprawling data center environments, server farm interconnects, and enterprise backbone networks. The cable achieves the full 40GB data rate specified by IEEE 802.3ba standards, ensuring maximum throughput and minimal latency. ## Construction and Safety The JBX03655 features robust plastic jacketing with LSZH (Low Smoke Zero Halogen) composition, meeting OFNR (Optical Fiber Non-conductive Riser) rating requirements. This construction is essential for building installations where fire safety codes mandate low-smoke, non-toxic cable materials. The cable's durable design withstands the rigors of data center environments while maintaining optimal performance across its 0-70°C operating temperature range. ## Compatibility and Integration This cable directly replaces the OEM Cisco part number QSFP-H40G-AOC25M, ensuring seamless integration into existing Cisco infrastructure. The QSFP+ form factor provides standardized connectivity with Cisco switches, transceivers, and network equipment, eliminating compatibility concerns and reducing deployment time. ## Certification and Compliance Comprehensively certified to Class 1 Laser standards, UL/FDA, and TUV specifications, this cable meets the highest safety and performance benchmarks. Full RoHS/ELV directive compliance ensures environmentally responsible manufacturing and disposal. These certifications provide peace of mind for mission-critical network deployments. ## Performance and Benefits Active optical cables eliminate the signal loss associated with passive copper or standard fiber solutions, enabling reliable 40GB communication over 25 meters without degradation. This makes the JBX03655 an excellent choice for connecting distant racks, separate equipment areas, or multi-cabinet configurations within data centers. The cable's superior performance translates to reduced errors, improved network reliability, and lower operational costs. ## Value and Support Backed by a 90-day limited warranty, this cable offers protection for your investment. Available for immediate shipment from multiple U.S. locations (Danville, CA and Beaufort, SC), with free standard shipping on orders exceeding $99. Custom brand programming is available for enterprise deployments requiring standardized identification across large-scale installations. The JBX03655 represents the optimal solution for organizations requiring reliable, high-performance 40GB connectivity in professional network environments.
