The JBX90088 85-meter LC/ST duplex singlemode fiber patch cable represents a professional-grade solution for critical network infrastructure requiring extended cable runs with superior optical performance. Engineered with precision specifications, this cable delivers reliable high-speed data transmission across enterprise and telecommunications environments. **Key Technical Specifications:** Featuring a 9/125 singlemode core with G.657.A1 grade glass fiber, the cable achieves exceptional low-loss performance. Insertion loss is guaranteed at ≤0.35dB (0.15dB typical), while return loss exceeds 20dB, ensuring minimal signal degradation and reflection. Attenuation performance meets strict standards at both 1310nm (0.25 dB/km) and 1550nm (0.35 dB/km) wavelengths, making it suitable for diverse applications including long-haul telecommunications. **Construction & Durability:** The duplex configuration combines two optical fibers in a single cable assembly, enabling bidirectional communication through a single pull. The cable's OFNR riser-rated jacket provides flame resistance and chemical stability, while the compact 1.8mm outside diameter facilitates installation in tight spaces and existing conduit infrastructure. Pink coloring aids in network organization and identification. **Compliance & Standards:** Fully TAA compliant for government procurement, RoHS/ELV certified per EU Directive 2002/95/EC. The cable meets rigorous ANSI/TIA/EIA-455-171-A-2001 attenuation testing standards, ensuring consistent performance across production runs. **Application & Compatibility:** LC/ST connector pairing (Type A to B crossover) makes this cable ideal for interconnecting singlemode equipment in data centers, carrier networks, and telecommunications facilities. The 85-meter length accommodates substantial distances between equipment racks or buildings. **Warranty & Support:** Backed by a 90-day limited warranty. Free standard shipping on orders exceeding $99. Custom lengths available for specialized installations. Ships from multiple U.S. locations (California, Texas, South Carolina) ensuring rapid delivery nationwide.
