The JBX42998 85-meter LC/UPC to LC/UPC singlemode fiber patch cable represents a critical component for modern data center, telecommunications, and enterprise networking environments. This simplex configuration delivers a single-direction fiber pathway optimized for applications requiring unidirectional signal transmission at maximum distances. **Technical Excellence:** Constructed with 9/125 micron singlemode fiber core and G.657.A1 specification glass fiber, this cable achieves superior performance metrics. Insertion loss is rated at ≤0.35dB (with typical performance of 0.15dB), while return loss maintains ≥20dB standards. Attenuation measurements comply with ANSI/TIA/EIA-455-171-A-2001, ensuring consistent performance at both 1310nm and 1550nm wavelengths commonly used in fiber optic systems. **Professional Installation Features:** The LC/UPC connectors provide a standard interface compatible with enterprise-grade networking equipment and patch panels. The 1.8mm outside diameter offers flexibility for routing through conduit systems and around obstacles. Yellow OFNR (Optical Fiber Non-conductive Riser) jacketing meets fire safety codes required for in-building risers and vertical runs, while the distinctive color facilitates identification and organization in complex cable management scenarios. **Compliance and Quality Assurance:** TAA compliant for government and public sector procurement, this cable meets RoHS/ELV directive requirements (EU 2002/95/EC). Each cable undergoes rigorous attenuation testing in accordance with industry standards, ensuring reliability and performance consistency. The 90-day limited warranty provides peace of mind on your infrastructure investment. **Practical Applications:** Ideal for long-distance campus interconnects, data center backbone connections, telecommunications facilities, and broadcast environments where signal integrity over extended runs is paramount. The 85-meter length accommodates large installations without intermediate amplification. **Flexible Solutions:** Custom lengths available to meet specific deployment requirements. Manufactured in Taiwan, United States, and China with consistent quality across all production facilities.
