The JBX43782 55-meter LC/UPC to ST/APC simplex singlemode fiber patch cable represents professional-grade connectivity for mission-critical network applications. This carefully engineered fiber optic cable combines superior performance specifications with practical installation features. **Technical Excellence** Constructed with 9/125 singlemode core using G.657.A1 glass fiber, this cable delivers exceptional optical performance. The low insertion loss of ≤0.35dB (0.15dB typical) ensures minimal signal degradation, while the ≥20dB return loss specification prevents reflective interference. Attenuation specifications are optimized for both 1310nm (0.25dB/km) and 1550nm (0.35dB/km) wavelengths, making this cable suitable for diverse network protocols. **Professional Features** The yellow OFNR (Optical Fiber Non-conductive Riser) jacket provides fire-rated protection suitable for building risers and elevated installations. At 1.8mm outside diameter, the compact design facilitates easy routing through conduits and cable trays. The straight-through polarity configuration ensures proper signal flow without crossing connections. **Compliance & Standards** TAA compliance makes this cable suitable for U.S. government projects and procurement contracts. RoHS/ELV certification ensures environmental responsibility. Manufacturing follows ANSI/TIA/EIA-455-171-A-2001 standards for attenuation testing, guaranteeing consistent quality across production batches. **Practical Advantages** Available in custom lengths beyond the standard 55 meters, allowing exact fit to your infrastructure needs. Multiple U.S. shipping locations in Danville CA, Fort Worth TX, and Beaufort SC ensure rapid delivery. Free standard shipping on orders exceeding $99 reduces total cost of ownership. The 90-day limited warranty provides peace of mind for critical installations. **Applications** Ideal for telecommunications networks, data center interconnects, enterprise LAN expansions, and carrier-grade fiber installations. The simplex configuration suits applications requiring single-direction transmission or where separate receive/transmit cables are preferred. Choose the JBX43782 for reliability, performance, and value in singlemode fiber connectivity.
