The JBX43545 3-meter ST/APC to FC/UPC simplex fiber patch cable represents a professional-grade solution for optical signal transmission in telecommunications, data centers, and network infrastructure applications. Engineered with precision to meet stringent industry standards, this cable combines reliability, performance, and compliance in a single offering. **Technical Specifications & Performance:** Constructed with 9/125 singlemode optical fiber and G.657.A1 glass fiber, the cable delivers superior signal propagation characteristics. The insertion loss rating of ≤0.35dB (typical 0.15dB) and return loss of ≥20dB ensure minimal signal degradation over the 3-meter span. Attenuation performance is tested and verified at both 1310 nm and 1550 nm wavelengths, meeting ANSI/TIA/EIA-455-171-A 2001 standards for consistent performance across different network topologies. **Build Quality & Safety:** The cable features OFNR (Optical Fiber Non-Conductive, Riser-rated) jacketing, making it suitable for installation in vertical cable runs and risers without additional conduit in most building codes. The 1.8mm outside diameter and bright yellow identification jacket facilitate easy routing, identification, and management in crowded equipment racks. Plastic accessory materials combined with riser-rated construction ensure fire safety compliance. **Compliance & Standards:** TAA compliant certification ensures this cable meets Buy American Act requirements for government and institutional purchasing. Full RoHS and ELV directive compliance demonstrates adherence to environmental and hazardous substance regulations. The cable is manufactured in Taiwan, the US, or China, with quality standards maintained across all production locations. **Flexibility & Customization:** While this listing features the 3-meter standard length, custom lengths are available to accommodate specific installation requirements, from shorter patch applications to extended runs. The simplex (single-strand) configuration supports unidirectional transmission for point-to-point applications or can be deployed as part of a bidirectional system using separate transmit and receive cables. **Shipping & Support:** Shipped from strategically located warehouses in Danville, California; Fort Worth, Texas; and Beaufort, South Carolina, orders benefit from free standard shipping on purchases exceeding $99. Each cable includes a 90-day limited warranty, providing confidence in product reliability. The ST/APC to FC/UPC connector pairing enables compatibility with diverse network equipment while delivering the low-loss performance demanded by modern optical systems.
