The JBX42088 85m LC/APC to SC/UPC Duplex Singlemode Fiber Patch Cable represents a premium solution for telecommunications and data center professionals requiring reliable, long-distance fiber connectivity. This cable is manufactured to exacting standards and tested in accordance with ANSI/TIA/EIA-455-171-A-2001, ensuring consistent performance across demanding applications. **Technical Specifications & Performance:** Features a 9/125 singlemode fiber core with G.657.A1 glass composition, providing excellent bend radius performance while maintaining signal integrity. The cable achieves exceptional attenuation characteristics: 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm. Maximum insertion loss is rated at 0.35dB with typical performance of just 0.15dB, while return loss exceeds 20dB—critical parameters for high-quality signal transmission in telecommunications networks. **Design & Durability:** The 1.8mm outside diameter duplex construction maintains a compact profile while the yellow OFNR (Riser Rated) jacket provides flame resistance and visibility. TAA compliance and RoHS/ELV certification meet stringent government procurement and environmental standards, making this cable ideal for federal installations and regulated industries. **Connectivity & Configuration:** LC/APC (Angled Physical Contact) connectors on one end mate with SC/UPC (Ultra Physical Contact) connectors on the other, implementing a Type A to B crossover configuration—the industry-standard polarity for duplex patch cords. This design eliminates compatibility issues and simplifies network troubleshooting. **Practical Advantages:** The 85-meter length accommodates long-distance rack-to-rack connections and facility-wide installations. Available in custom lengths for specialized applications. Ships from strategically located US warehouses (California, Texas, and South Carolina) with complimentary standard shipping on orders exceeding $99. **Applications:** Ideal for telecommunications infrastructure, data centers, campus networks, and any environment requiring singlemode fiber patch connections with superior signal quality and regulatory compliance.
