The JBX43602 FC/APC to ST/UPC simplex fiber patch cable represents professional-grade connectivity solutions for modern optical fiber networks. This 1.5-meter cable combines precision engineering with proven reliability, making it an essential component for telecommunications systems, data centers, and enterprise networking environments. **Technical Excellence:** Constructed with 9/125 singlemode fiber core and G.657.A1 glass fiber, this cable delivers superior signal transmission characteristics. The insertion loss specification of ≤0.35dB (0.15dB typical) and return loss of ≥20dB ensure optimal signal fidelity. Performance has been rigorously tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, with attenuation rates of 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm. **Practical Design Features:** The bright yellow OFNR riser-rated jacket provides both safety compliance and ease of identification in complex cable management scenarios. With a compact 1.8mm outer diameter, the cable fits easily through conduits and tight spaces without compromising durability. The straight-through polarity configuration simplifies installation and reduces configuration errors. **Compliance & Quality:** Fully TAA compliant and RoHS/ELV certified, this cable meets government and environmental standards. The 90-day limited warranty provides peace of mind for critical installations. **Flexibility & Availability:** While this listing features the 1.5-meter standard length, custom lengths are available to match your specific deployment requirements. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. **Ideal Applications:** Perfect for connecting fiber distribution panels to network equipment, laboratory instruments, or telecommunications infrastructure where precise signal transmission is critical. The simplex configuration serves single-direction transmission needs, while the FC/APC to ST/UPC connectors provide compatibility across diverse equipment platforms.
