The JBX43256 LC/APC to ST/UPC simplex singlemode fiber patch cable represents a premium solution for mission-critical fiber optic network installations. This 25-meter cable combines precision engineering with reliable performance specifications that meet or exceed industry standards. **Technical Excellence:** Constructed with 9/125 singlemode fiber and G.657.A1 grade glass, this cable delivers superior optical performance. Attenuation testing confirms 0.25dB/km at 1310nm and 0.35dB/km at 1550nm, with typical insertion loss of just 0.15dB and guaranteed maximum of 0.35dB. Return loss exceeds 20dB, ensuring minimal signal reflection and optimal transmission quality. These specifications make it ideal for long-distance telecommunications, data center interconnects, and high-speed network backbone applications. **Practical Design Features:** The bright yellow OFNR-rated (riser-rated) jacket provides excellent visibility in cable trays and between floors, simplifying installation and future maintenance. The 1.8mm outer diameter ensures compatibility with standard cable management systems while maintaining durability. The straight-through polarity configuration enables straightforward point-to-point connections between LC/APC and ST/UPC terminated equipment. **Compliance & Reliability:** TAA compliant certification qualifies this cable for U.S. government and federal projects. RoHS/ELV directive compliance ensures environmentally responsible manufacturing. The cable ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99, backed by a 90-day limited warranty. **Custom Availability:** While this listing features the 25-meter standard length, custom lengths are available to meet specific installation requirements, reducing waste and improving cost efficiency. **Applications:** Perfect for telecommunications carriers, ISP backbone networks, data center fiber infrastructure, campus networking, and any application requiring reliable singlemode simplex signal transmission. The LC/APC connector combination minimizes back reflection, making it especially suitable for RF and analog transmission applications. **Industry Standards Compliance:** Manufactured to ANSI/TIA/EIA standards with rigorous attenuation testing, ensuring performance consistency across manufacturing batches.
