The JBX89028 85-meter LC/LC duplex singlemode fiber patch cable represents a professional-grade solution for mission-critical fiber optic installations. Constructed with precision-engineered 9/125 micrometer singlemode fiber, this cable delivers exceptional performance across standard telecommunications wavelengths. **Technical Specifications:** This cable features LC/UPC connectors configured in Type A to B crossover polarity, the industry standard for duplex patch cord applications. The 1.8mm outer diameter jacket is OFNR-rated (riser rated), providing excellent flame resistance suitable for vertical cable runs in commercial buildings. Attenuation testing per ANSI/TIA/EIA-455-171-A standards confirms performance of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm, ensuring signal fidelity over extended distances. **Compliance and Certification:** TAA-compliant and RoHS/ELV certified, this cable meets stringent federal acquisition standards and environmental directives, making it suitable for government contracts and environmentally-conscious organizations. The EU directive 2002/95/EC compliance ensures responsible manufacturing practices. **Applications:** Perfect for telecommunications infrastructure, data center fiber backbone installations, ISP network expansions, and metropolitan area networks (MANs) requiring reliable long-distance fiber connections. The 85-meter length accommodates building-to-building or floor-to-floor connectivity in large facilities. **Value Proposition:** Available in custom lengths, manufactured in Taiwan, US, or China facilities, and backed by a 90-day limited warranty. Free standard shipping on orders exceeding $99 from convenient distribution centers in California, Texas, and South Carolina ensures rapid delivery across North America. **Maintenance:** LC connectors require proper handling and dust caps to maintain performance. Regular inspection of connector ends and jacketing extends cable lifespan in demanding environments.
