The JBX43616 is a professional-grade 25-meter simplex fiber optic patch cable designed for critical network infrastructure applications. This cable bridges FC/APC and ST/UPC connectors, making it essential for diverse network topologies requiring mixed connector compatibility. **Technical Specifications:** This cable utilizes 9/125 singlemode fiber core technology, the industry standard for long-distance, high-capacity telecommunications. The G.657.A1 glass fiber specification provides enhanced bend radius performance without compromising transmission characteristics. With an outside diameter of 1.8mm and lightweight plastic accessories, installation is straightforward in congested cable runs. **Performance Characteristics:** Tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, this cable delivers exceptional performance metrics. Insertion loss remains at or below 0.35dB at both 1310nm and 1550nm wavelengths, with typical performance at just 0.15dB. Return loss exceeds 20dB, ensuring signal integrity across extended distances. These specifications guarantee minimal attenuation (0.25 dB/km at 1310nm, 0.35 dB/km at 1550nm). **Installation & Compliance:** The OFNR riser-rated jacketing meets fire code requirements for installation in building risers and plenum spaces. The straight-through polarity configuration ensures seamless signal transmission without cross-talk. TAA compliance makes this cable eligible for government contracts and institutional procurement processes. RoHS/ELV certification confirms environmental responsibility and regulatory adherence. **Shipping & Availability:** Available in custom lengths for specialized applications. Ships free on orders exceeding $99 from multiple U.S. distribution centers (Danville CA, Fort Worth TX, Beaufort SC), ensuring rapid delivery. 90-day limited warranty provides peace of mind on your investment. **Applications:** Ideally suited for telecommunications networks, ISP infrastructure, enterprise data centers, laboratory environments, and CATV systems requiring reliable singlemode connectivity. The yellow jacket aids in cable identification during installation and troubleshooting.
