The JBX43148 85m SC/APC to SC/UPC Simplex Singlemode Fiber Patch Cable represents professional-grade optical connectivity for demanding network environments. Built with precision engineering, this cable delivers exceptional performance for long-distance fiber signal transmission in telecommunications, data centers, and enterprise networks. Technical Specifications: This singlemode fiber cable features a 9/125 micron core/cladding diameter with G.657.A1 glass fiber, specifically designed for low-loss signal propagation. The cable achieves insertion loss of ≤0.35dB (typically 0.15dB) and return loss of ≥20dB, meeting rigorous ANSI/TIA/EIA-455-171-A standards. Attenuation rates are optimized at both 1310nm (0.25dB/km) and 1550nm (0.35dB/km) wavelengths. Connector Configuration: The SC/APC to SC/UPC connector pairing accommodates mixed polarity networks while maintaining signal integrity. The straight-through polarity design ensures reliable bidirectional communication. SC connectors are industry-standard for telecommunications applications, offering secure bayonet coupling and excellent repeatability. Construction & Durability: The 1.8mm outside diameter yellow jacket is OFNR riser-rated, meeting fire safety codes for in-building installations. The plastic accessory construction provides durability while maintaining flexibility for deployment in tight spaces. RoHS and ELV compliance ensures environmental responsibility without sacrificing performance. Applications: Ideal for backbone connections, server-to-switch installations, long-distance rack connections, and telecommunications infrastructure. The 85-meter length eliminates the need for multiple spliced segments, reducing insertion loss and improving reliability. Custom lengths are available for specialized deployment scenarios. Compliance & Warranty: TAA-compliant for government and institutional procurement. Backed by a 90-day limited warranty. Manufactured in Taiwan, the United States, or China with consistent quality standards. Ships free on orders over $99 from multiple U.S. warehouses for rapid delivery.
