The JBX91058 85m LC/SC Duplex Singlemode Fiber Patch Cable represents a professional-grade solution for telecommunications and data center environments requiring long-distance fiber optic connectivity. Manufactured to exacting standards and available from multiple US distribution centers, this cable delivers the reliability and performance characteristics essential for critical network infrastructure. **Technical Specifications:** This duplex patch cable features a 9/125 micron singlemode core, the industry standard for long-distance signal transmission. The LC/UPC to SC/UPC connector configuration with Type A to B crossover polarity ensures compatibility with most enterprise networking equipment. At 85 meters, this length accommodates extensive cable runs while maintaining signal integrity through low attenuation ratings of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm—well within industry performance expectations. **Compliance and Safety:** TAA (Trade Agreements Act) compliance makes this cable suitable for government contracts and sensitive applications. RoHS/ELV certification confirms lead-free construction meeting EU directive 2002/95/EC requirements. The OFNR (Riser Rated) jacket designation indicates safe use in vertical cable runs and plenum-adjacent installations, providing peace of mind in multi-story facilities. **Design and Durability:** The compact 1.8mm outer diameter jacketing allows flexible routing through conduit and cable trays without excessive bend radius concerns. The green jacket provides excellent visual identification in complex multi-cable installations, reducing troubleshooting time and installation errors. **Applications:** Ideal for telecommunications service providers, Internet Service Providers, enterprise data centers, and campus networking environments where singlemode fiber extends connectivity over distances where multimode would suffer excessive attenuation. Commonly deployed in backbone connections, long-distance inter-building links, and telecommunication infrastructure. **Value and Support:** Offered with a 90-day limited warranty and free standard shipping on orders exceeding $99, this TAA-compliant cable provides exceptional value for enterprise procurement. Custom lengths are available to meet specific installation requirements. Attenuation testing per ANSI/TIA/EIA-455-171-A standards ensures performance verification before deployment.
