The JBX43775 20-meter LC/UPC to ST/APC simplex singlemode fiber patch cable represents a premium connectivity solution for demanding telecommunications and data center applications. This cable is engineered with precision-matched connectors and high-quality singlemode fiber to ensure optimal signal integrity across long-distance network runs. Key Technical Features: The cable utilizes 9/125 singlemode fiber with G.657.A1 glass composition, the industry standard for singlemode applications. With a 1.8mm outside diameter and flexible plastic construction, it integrates seamlessly into existing network infrastructure. The riser-rated OFNR jacketing supports vertical runs between building floors while maintaining fire-safety compliance. Performance Specifications: Insertion loss is maintained at ≤0.35dB (0.15dB typical), with return loss exceeding 20dB—both critical for maintaining signal quality. Attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm ensure reliable performance across the full telecommunications spectrum. Compliance & Certifications: TAA compliance makes this cable ideal for U.S. government and public sector projects. Full RoHS/ELV directive compliance (EU 2002/95/EC) ensures environmental responsibility. The cable is tested to ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing quality and consistency. Applications: Perfect for backbone connections, telecommunications equipment interconnects, data center networks, and enterprise installations requiring simplex transmission. The yellow jacket provides visibility in crowded patch panels and cable runs. Customization & Support: Available in custom lengths to fit your specific installation requirements. Backed by a 90-day limited warranty. Ships from three strategic U.S. locations (California, Texas, South Carolina) ensuring rapid delivery. Free standard shipping on orders exceeding $99.
