The JBX42268 85-meter LC/APC to ST/UPC duplex singlemode fiber patch cable represents enterprise-class connectivity for fiber optic networks. Built to exacting standards, this cable delivers reliable performance in demanding telecommunications, data center, and network infrastructure applications. **Technical Excellence:** Features a 9/125 singlemode core utilizing G.657.A1 glass fiber technology, optimized for extended-distance signal transmission. With attenuation rates of 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm, this cable minimizes signal loss over the full 85-meter length. The impressive insertion loss specification of ≤0.35dB (0.15dB typical) and return loss ≥20dB ensure superior optical performance. **Professional Construction:** The cable features OFNR (Optical Fiber Non-Conductive Riser) rated yellow jacketing with 1.8mm outer diameter, meeting demanding fire safety codes for indoor building installations. The duplex configuration with LC/APC to ST/UPC connectors utilizes Type A to B crossover polarity, the industry standard for most duplex patch applications. **Compliance & Reliability:** Fully TAA (Trade Agreements Act) compliant for government and federal procurement. RoHS and ELV directive compliant (EU 2002/95/EC), manufactured in Taiwan, US, or China facilities. All cables undergo rigorous attenuation testing per ANSI/TIA/EIA-455-171-A-2001 standards, backed by a 90-day limited warranty. **Flexible Ordering:** While this 85-meter configuration suits many installations, custom lengths are available to match your specific network topology. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. **Ideal Applications:** Perfect for campus network interconnections, long-distance departmental links, and data center backbone installations where extended reach and superior optical performance are essential. The professional yellow jacket provides easy visual identification in complex cable management systems.
