The JBX43446 75-meter FC/APC to FC/UPC simplex singlemode fiber patch cable represents a professional-grade solution for demanding telecommunications and data center environments. Built with precision manufacturing standards, this cable delivers exceptional optical performance combined with robust construction for reliable long-term operation. **Technical Specifications:** This singlemode fiber cable features a 9/125 micron core diameter with G.657.A1 glass fiber specifications, ensuring compatibility with modern telecom infrastructure. The FC/APC (Angled Physical Contact) to FC/UPC (Ultra Physical Contact) configuration accommodates mixed connector environments while maintaining optimal signal quality. The simplex design transmits signals in a single direction, making it ideal for unidirectional applications. **Performance Metrics:** The cable achieves exceptional optical characteristics with insertion loss of just 0.15dB typical (≤0.35dB maximum) and return loss exceeding 20dB. Attenuation testing confirms 0.25dB/km at 1310nm wavelength or 0.35dB/km at 1550nm, meeting or exceeding ANSI/TIA/EIA-455-171-A-2001 standards. These specifications ensure minimal signal degradation over the 75-meter span. **Safety and Compliance:** Riser-rated OFNR jacketing provides fire safety in vertical cable runs, meeting building code requirements. The cable is fully TAA compliant for government and federal projects and carries RoHS/ELV certification for environmental responsibility. Available lengths of 75 meters, with custom lengths available for specialized installations. **Applications and Use Cases:** Perfect for telecommunications networks, data center interconnects, enterprise campus networks, and telecom equipment installations. The yellow jacket provides superior visibility for cable management and troubleshooting. The 1.8mm outside diameter enables easy routing through conduit and cable trays. **Logistics and Support:** Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) ensuring quick delivery. Free standard shipping on orders exceeding $99. Backed by a comprehensive 90-day limited warranty covering manufacturing defects. Ships in secure packaging (10x10x10 case configuration) protecting the cable during transit. **Custom Solutions:** While the standard 75-meter length serves most applications, custom lengths are available to meet specific project requirements.
