The JBX43551 ST/APC to FC/UPC simplex fiber patch cable represents a professional-grade solution for single-mode fiber optic networks requiring reliable signal transmission across medium distances. This 9-meter cable is engineered to deliver consistent performance in demanding telecommunications, data center, and network infrastructure applications. **Technical Specifications:** The cable features a precision-engineered 9/125 singlemode core constructed from G.657.A1 glass fiber, a specification that ensures low-loss signal transmission at standard telecommunications wavelengths. With attenuation measurements of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm, this cable performs within optimal parameters for long-distance signal integrity. The insertion loss specification of ≤0.35dB (typical 0.15dB) and return loss ≥20dB exceed ANSI/TIA/EIA-455-171-A-2001 standards, ensuring superior connector interface quality. **Construction & Durability:** The 1.8mm outside diameter provides space-efficient routing through cable trays and conduits, while the OFNR (Optical Fiber Nonconductive Riser) jacketing ensures fire safety and meets building codes for in-wall installations. The yellow jacket facilitates easy cable identification and management within complex network infrastructures. **Compliance & Certifications:** Fully TAA compliant for government procurement and RoHS/ELV certified for environmental safety, this cable meets stringent regulatory requirements. The straight-through polarity configuration ensures seamless integration into existing network architectures. **Applications:** Ideal for data center interconnects, telecommunications backbone installations, campus network infrastructure, and any application requiring reliable single-mode fiber connectivity. The simplex design suits point-to-point transmission scenarios. **Value Proposition:** With free standard shipping on orders over $99, a 90-day limited warranty, and availability in custom lengths, this cable offers flexibility and cost-effectiveness. Multiple manufacturing locations (Taiwan, US, China) ensure consistent quality and reliable supply chains.
