The JBX03545 5m Palo Alto Networks compatible 40GBASE-SR4 QSFP+ to 4x SFP+ active optical breakout cable represents a sophisticated solution for enterprise networking infrastructure. This premium-grade cable combines cutting-edge optical technology with proven reliability standards required by modern data centers and network environments. **Technical Excellence** Built to IEEE 802.3ba specifications, this cable supports full 40GB/s transmission speeds while maintaining signal integrity across its 5-meter length. The OM3 50/125 multimode fiber core with 8 strands ensures optimal light transmission and minimal signal loss, delivering consistent performance for bandwidth-intensive applications. **Architecture and Design** The active optical cable (AOC) features integrated optical-to-electrical conversion at connector interfaces, eliminating the signal attenuation problems associated with passive copper breakout solutions. The OFNR-rated LSZH jacketing provides enhanced fire safety performance while maintaining flexibility for installation in tight spaces and cable trays. **Compliance and Certification** This cable meets stringent international standards including RoHS/ELV directives, EU 2002/95/EC compliance, and features comprehensive safety certifications: Class 1 Laser designation, UL/FDA approval (21CFR 1040.10), TUV certification, and LN #50 7/2001 compliance. These certifications ensure safe operation in diverse environments. **Operational Specifications** Operating effectively within a 0-70°C temperature range, the cable performs reliably in controlled data center environments and ventilated network closets. Its compact 12x12x5mm dimensions facilitate high-density installations while maintaining thermal management. **Application Scenarios** Ideally suited for Palo Alto Networks firewall deployments, this breakout cable excels in scenarios requiring granular port distribution without quality compromise. Common applications include enterprise security appliance upgrades, data center network segmentation, and high-availability cluster implementations. **Value Proposition** With free standard shipping on orders exceeding $99 and availability from multiple U.S. fulfillment centers (Danville, CA and Beaufort, SC), customers enjoy rapid deployment capability. The 90-day limited warranty provides peace of mind for mission-critical installations. **Maintenance Considerations** The sealed connector design minimizes dust accumulation and requires minimal maintenance. Proper cable routing and securing prevent stress on fiber strands and connector interfaces, ensuring longevity and consistent performance throughout the cable's operational lifecycle.
