The JBX42659 90-meter SC/APC to LC/UPC duplex singlemode fiber patch cable represents the ideal solution for professional-grade fiber optic network installations. Designed for applications requiring long-distance signal transmission with minimal signal degradation, this cable combines advanced optical technology with rugged construction. **Technical Excellence** Built with 9/125 singlemode fiber and G.657.A1 glass composition, this cable achieves industry-leading performance specifications. Insertion loss measures ≤0.35dB (0.15dB typical), while return loss exceeds 20dB—ensuring crystal-clear signal transmission. Attenuation performance is tested at both 1310nm (0.25 dB/km) and 1550nm (0.35 dB/km) wavelengths, providing versatility across diverse network architectures. **Construction & Durability** The cable features a compact 1.8mm outer diameter with vibrant yellow OFNR-rated (Optical Fiber Non-conductive Riser) jacketing. This riser-rated design meets stringent building codes and fire safety standards while protecting the delicate fiber core from environmental hazards. The Type A to B crossover polarity configuration represents the most common duplex patch cord standard, simplifying installation and reducing compatibility issues. **Compliance & Standards** Fully TAA (Trade Agreements Act) compliant and RoHS/ELV certified, this cable meets government procurement requirements and environmental regulations. Attenuation testing conforms to ANSI/TIA/EIA-455-171-A standards, guaranteeing consistent quality across manufacturing batches. **Practical Benefits** Available in custom lengths to match your specific installation requirements, this duplex configuration transmits bidirectional signals over a single cable run, reducing installation complexity. Free standard shipping on orders over $99 and backed by a 90-day limited warranty, providing peace of mind for your network investment. **Ideal Applications** Perfect for data center interconnects, telecommunications networks, FTTH installations, and enterprise-grade fiber optic systems requiring extended cable runs with minimal signal loss.
