The JBX43421 FC/APC to FC/UPC Simplex Fiber Patch Cable represents professional-grade optical connectivity engineered for mission-critical applications. This 1-meter cable delivers exceptional performance in telecommunications, data center, and network infrastructure environments. **Technical Specifications:** Featuring a 9/125 micron singlemode fiber core with G.657.A1 designation, this cable provides ultra-low attenuation characteristics: 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm. The measured insertion loss of ≤0.35dB (0.15dB typical) ensures minimal signal degradation, while return loss ≥20dB guarantees excellent signal reflection control. These specifications exceed ANSI/TIA/EIA-455-171-A-2001 standards. **Construction Quality:** The cable features a robust 1.8mm outside diameter with OFNR (Riser Rated) jacketing, meeting fire safety requirements for building installations. The yellow jacket provides easy identification in complex fiber installations. Manufactured with precision in Taiwan, the US, and China, this cable maintains consistent quality across production locations. **Compliance & Certifications:** Fully TAA (Trade Agreements Act) compliant, making it suitable for government and institutional procurement requirements. RoHS/ELV certified under EU directive 2002/95/EC, ensuring environmental responsibility and safe disposal. **Applications:** Ideal for telecommunications facilities, data centers, network backbone installations, and laboratory environments requiring precise optical connections. The FC/APC connector configuration is particularly suited for demanding applications requiring minimal back-reflection. **Support & Logistics:** Included 90-day limited warranty provides peace of mind. Available in custom lengths for specialized installations. Ships from strategically located facilities (Danville CA, Fort Worth TX, and Beaufort SC) with complimentary standard shipping on orders exceeding $99. Invest in reliable optical connectivity with the JBX43421—where performance meets compliance in professional fiber optics.
