The JBX43586 ST/APC to FC/APC Simplex Singlemode Fiber Patch Cable is a mission-critical component for telecommunications networks, data centers, and fiber optic infrastructure installations. This 25-meter cable combines precision engineering with cost-effective performance to meet demanding connectivity requirements. **Technical Specifications:** Built on proven 9/125 singlemode fiber architecture, this cable achieves exceptional signal integrity with measured insertion loss of ≤0.35dB at 0.15dB typical, and return loss exceeding 20dB—exceeding industry standards for long-distance transmission. The G.657.A1 glass fiber specification ensures compatibility with modern bend-insensitive fiber applications while maintaining superior attenuation characteristics: 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm. **Construction & Durability:** The cable features a robust yellow OFNR (Optical Fiber Non-conductive Riser) rated jacket measuring 1.8mm in outer diameter, providing flame resistance and optimal performance in indoor cable runs. The vibrant yellow color simplifies inventory management and network troubleshooting by enabling rapid visual identification. **Compliance & Standards:** TAA compliant manufacturing ensures compliance with U.S. federal procurement regulations. RoHS/ELV certification confirms environmental responsibility, while testing per ANSI/TIA/EIA-455-171-A-2001 validates performance metrics. **Simplex Configuration:** The simplex design supports unidirectional signal transmission, ideal for applications requiring single-direction fiber connectivity. Straight-through polarity ensures predictable signal flow. **Flexibility & Customization:** While this product features a standard 25-meter length, custom lengths are available to match your specific installation requirements, eliminating waste and optimizing cost-effectiveness. **Support & Warranty:** Every cable includes a 90-day limited warranty, reflecting manufacturer confidence in product quality. Free standard shipping applies to orders exceeding $99, with fulfillment from regional distribution centers in California, Texas, and South Carolina for rapid delivery. **Applications:** Ideal for telecommunications networks, DWDM systems, fiber-to-the-premises installations, data center interconnects, and any application requiring reliable singlemode fiber connectivity with APC connector technology.
