The JBX42999 90-meter LC/UPC to LC/UPC singlemode fiber patch cable represents the gold standard in professional-grade optical connectivity solutions. Engineered for mission-critical applications where signal integrity and reliability are paramount, this simplex cable delivers consistent performance in telecommunications, data centers, and enterprise network environments. **Technical Excellence** Built with a 9/125 singlemode fiber core conforming to G.657.A1 specifications, this cable achieves exceptional attenuation characteristics: 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm. The maximum insertion loss of 0.35dB (0.15dB typical) and return loss of ≥20dB ensure minimal signal degradation even across the full 90-meter run. Attenuation testing follows rigorous ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing reliable performance. **Construction and Durability** The cable features a yellow OFNR riser-rated PVC jacket, providing both visibility in installations and fire safety compliance for building-rated applications. The compact 1.8mm outer diameter enables flexible routing through conduit and cable trays while maintaining robust protection. LC/UPC connectors offer superior polishing and low back-reflection characteristics essential for sensitive optical systems. **Compliance and Certification** TAA (Trade Agreements Act) compliant manufacturing ensures government and enterprise procurement compatibility. RoHS/ELV compliance with EU Directive 2002/95/EC confirms environmental responsibility. Available in multiple manufacturing origins (Taiwan, US, China) with consistent quality standards. **Application Scenarios** Ideal for inter-building fiber optic runs, data center backbone connections, telecommunications infrastructure, and any long-distance singlemode fiber installations requiring pristine signal transmission. The 90-meter length accommodates substantial distance requirements in campus networks and service provider deployments. **Support and Customization** Backed by a comprehensive 90-day limited warranty and available in custom lengths for specialized applications. Ships from multiple US locations (California, Texas, South Carolina) with free standard shipping on orders over $99, ensuring rapid deployment and cost-effective logistics.
