The JBX42267 80-meter LC/APC to ST/UPC duplex singlemode fiber patch cable represents professional-grade connectivity for mission-critical network infrastructure. Engineered with precision manufacturing standards, this cable delivers exceptional performance in telecommunications, data center, and enterprise networking applications. **Technical Specifications:** This singlemode fiber cable features a 9/125 core diameter with G.657.A1 glass fiber composition, providing superior bend radius performance compared to standard G.652 fiber. The cable extends 80 meters with duplex configuration, enabling bi-directional communication through simultaneous transmission on two fibers. Operating wavelengths support standard telecom bands with attenuation of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm, ensuring signal integrity over long distances. **Connector Configuration:** The LC/APC to ST/UPC connector pairing accommodates Type A to B crossover polarity—the industry standard for duplex patch cords. APC (Angled Physical Contact) connectors on the LC side provide superior return loss (≥20dB) and minimal signal reflection, while UPC (Ultra Physical Contact) ST connectors offer compatibility with legacy installations. **Construction and Compliance:** Manufactured with 1.8mm outside diameter plastic jacketing rated OFNR (Optical Fiber Non-Conductive Riser), this cable meets fire safety requirements for in-building vertical runs. The yellow jacket provides easy identification in complex cable environments. TAA compliance ensures eligibility for U.S. government contracts and procurement, while RoHS/ELV directives confirm environmental responsibility. **Applications:** • Data center fiber backbones • Telecommunications infrastructure • Campus network connections • Long-distance signal transmission • Network testing and certification • Enterprise fiber deployments **Quality Assurance:** Tested per ANSI/TIA/EIA-455-171-A-2001 standards with documented insertion loss performance. Includes 90-day limited warranty. Custom lengths available for specific installation requirements. Ships from multiple U.S. locations with free standard shipping on orders exceeding $99.
