The JBX42683 60-meter FC/APC to LC/UPC duplex singlemode fiber patch cable represents a premium solution for demanding optical network environments where signal reliability and performance consistency are paramount. This professional-grade interconnect cable is specifically designed to support long-distance signal transmission in telecommunications networks, internet service providers, data centers, and enterprise networking infrastructure. Technical Excellence: Built with G.657.A1 glass fiber featuring a 9/125 micron singlemode core, this cable delivers industry-leading optical performance. The attenuation specifications (0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm) ensure minimal signal loss over the full 60-meter length, making it ideal for both conventional and ultra-low-loss applications. Insertion loss testing shows consistent results of ≤0.35dB (typical 0.15dB), while return loss exceeds 20dB, guaranteeing excellent signal reflection performance for duplex communication systems. Connector Compatibility: The FC/APC (angled physical contact) to LC/UPC (uniboot physical contact) configuration accommodates Type A to B crossover polarity, the most common duplex patch cord arrangement. This connector pairing bridges legacy FC-based systems with modern LC-infrastructure, making it invaluable for network upgrades and hybrid deployments. Physical Specifications: The 1.8mm diameter yellow jacket provides optimal balance between flexibility and durability. The 2mm compact design suits dense patch panel environments while the yellow color coding enhances cable management and troubleshooting efficiency. OFNR (Optical Fiber Non-conductive Riser) rating permits safe installation in vertical building applications without conduit. Compliance & Quality: TAA (Trade Agreements Act) compliance ensures this cable meets U.S. government procurement requirements. RoHS/ELV directives confirm environmental responsibility. All products are tested to ANSI/TIA/EIA-455-171-A-2001 standards and backed by a 90-day limited warranty. Manufacturing locations in Taiwan, United States, and China provide supply chain flexibility with strategic U.S. warehouse distribution from Danville CA, Fort Worth TX, and Beaufort SC. Applications: Ideal for telecommunications equipment interconnects, fiber-to-the-premises (FTTP) networks, data center cross-connects, campus backbone networks, and any application requiring reliable long-distance singlemode signal transmission. Custom lengths available for specialized requirements.
