The JBX43660 0.5m LC/UPC to FC/APC simplex singlemode fiber patch cable represents premium connectivity for telecommunications infrastructure, data center operations, and fiber optic networking applications. This meticulously engineered cable bridges two industry-standard connector types, enabling seamless integration between LC/UPC and FC/APC-equipped equipment. Superior Technical Performance: Built with 9/125 singlemode fiber and G.657.A1 glass specifications, this cable maintains exceptional signal integrity across 1310nm and 1550nm wavelengths. The measured insertion loss of ≤0.35dB (0.15dB typical) ensures minimal signal degradation, while return loss of ≥20dB prevents unwanted signal reflection. Attenuation specifications of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm confirm compliance with telecommunications standards. Durable Construction: The 1.8mm outside diameter provides flexibility without compromising structural integrity. The yellow OFNR (Optical Fiber Non-Conductive Riser) jacket offers flame resistance, environmental protection, and convenient color-coding for network administration. The straight-through polarity ensures consistent performance in mixed-connector environments. Compliance & Reliability: TAA (Trade Agreements Act) compliance makes this cable suitable for government procurement. Full RoHS/ELV directive adherence ensures environmental responsibility. Third-party attenuation testing per ANSI/TIA/EIA-455-171-A standards guarantees measurable quality. The 90-day limited warranty demonstrates manufacturer confidence. Applications: Ideal for telecommunications facilities, enterprise data centers, laboratory environments, and network upgrade projects requiring LC/UPC to FC/APC connectivity. The 0.5m length suits patch panels, equipment interconnections, and confined installation spaces. Availability: Ships from multiple US locations (Danville CA, Fort Worth TX, Beaumont SC) with free standard shipping on orders exceeding $99. Custom lengths available upon request to accommodate specific deployment requirements. Packaged in protective 10x10x10 case specifications for secure transport.
