The JBX42257 30-meter LC/APC to ST/UPC duplex singlemode fiber patch cable represents a premium solution for demanding network environments requiring reliable, high-speed optical connectivity. Built with precision engineering and quality materials, this cable delivers the performance characteristics necessary for modern data center, telecommunications, and enterprise network infrastructure applications. Technical Excellence: The cable utilizes 9/125 singlemode fiber with G.657.A1 specifications, optimized for long-distance signal transmission with minimal attenuation. Performance metrics include insertion loss of ≤0.35dB (0.15dB typical) at standard wavelengths and return loss ≥20dB, ensuring signal fidelity across critical network links. Attenuation rates of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm meet or exceed industry standards for singlemode fiber applications. All performance testing follows ANSI/TIA/EIA-455-171-A-2001 standards. Design and Durability: The distinctive yellow jacket provides immediate visual identification in complex network installations, reducing troubleshooting time and installation errors. The compact 1.8mm outside diameter facilitates routing through crowded cable management systems without compromising bend radius. OFNR (Optical Fiber, Non-conductive, Riser rated) jacketing ensures safety compliance in building environments and plenum spaces. Compliance and Reliability: TAA (Trade Agreements Act) compliance makes this cable suitable for government and regulated procurement environments. RoHS/ELV directives compliance ensures environmental responsibility. The 90-day limited warranty provides confidence in product quality and durability. Applications: Ideal for connecting network equipment in data centers, telecommunication facilities, universities, hospitals, and enterprise campuses. The LC/APC to ST/UPC crossover configuration accommodates diverse network architectures and legacy equipment integration. Availability and Support: Custom length configurations are available for specialized installations. Multiple fulfillment centers ensure rapid delivery with free standard shipping on qualifying orders. The product is compatible with existing network infrastructure while maintaining flexibility for future upgrades.
