The JBX42684 65-meter FC/APC to LC/UPC duplex singlemode fiber patch cable represents a critical infrastructure component for modern telecommunications, data centers, and enterprise networks. This professional-grade cable combines precision engineering with practical design features to deliver reliable, long-distance signal transmission. Technical Excellence: Built with 9/125 singlemode fiber and G.657.A1 glass fiber, this cable meets ANSI/TIA/EIA standards for attenuation testing. The insertion loss specification of ≤0.35dB (typical 0.15dB) ensures minimal signal degradation, while return loss exceeding 20dB provides superior connector performance. Attenuation rates of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm make this cable ideal for both short-reach and long-distance applications. Connector Configuration: The FC/APC to LC/UPC connection provides Type A to B crossover polarity—the most common configuration for duplex patch cords. This ensures compatibility with standard network equipment while maintaining signal integrity. The duplex design allows simultaneous bidirectional data transmission. Compliance & Safety: TAA compliance makes this cable suitable for government and federally-funded projects. RoHS/ELV directive compliance ensures environmental responsibility. OFNR (Optical Fiber Non-conductive Riser) rating permits installation in vertical building pathways and plenum spaces. Practical Features: The 1.8mm outside diameter and 5mm width enable efficient cable management in crowded installations. The bright yellow jacket provides instant visual identification, reducing installation errors and simplifying maintenance. Custom lengths are available for specialized applications. Applications: Perfect for telecommunications networks, data center interconnections, campus networks, and long-distance network expansions. The 65-meter length bridges extended distances while maintaining performance standards. Warranty & Support: Backed by a 90-day limited warranty and available for standard shipping on orders over $99, with domestic shipping from multiple locations. This investment in quality fiber infrastructure provides years of reliable network operation.
