The JBX43716 SC/APC to LC/UPC 4-meter simplex singlemode fiber patch cable represents professional-grade connectivity for demanding fiber optic applications. This carefully engineered solution combines precision manufacturing with reliable performance specifications that exceed industry standards. **Key Features:** This fiber patch cable features a 9/125 singlemode core with G.657.A1 glass fiber, delivering optimal performance for long-distance, high-bandwidth signal transmission. The SC/APC (angled physical contact) to LC/UPC (straight physical contact) configuration accommodates diverse equipment configurations common in modern network infrastructure. **Performance Specifications:** With insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB, this cable minimizes signal degradation across your network. Attenuation rates of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm ensure reliable transmission across extended distances. These specifications exceed standard requirements for data center and telecom applications. **Construction & Durability:** The cable features riser-rated (OFNR) jacketing, meeting fire safety requirements for in-building installations. At 1.8mm outside diameter with plastic accessories, it offers flexibility without compromising durability. The bright yellow jacket provides easy identification in cable trays and patch panels. **Compliance & Standards:** Fully compliant with RoHS/ELV directives and TAA regulations, this cable qualifies for government procurement and enterprise deployments. Manufactured in Taiwan, the United States, or China with consistent quality standards, and backed by a 90-day limited warranty. **Ideal Applications:** - Data center interconnects - Telecommunications infrastructure - Network backbone installations - Fiber-to-the-premises (FTTP) systems - Enterprise network upgrades - Research and laboratory environments **Custom Options Available:** While this product ships in standard 4-meter length, custom lengths are available to meet specific installation requirements. Contact our sales team for bulk orders or specialized configurations. **Value Proposition:** Combining affordability with professional-grade performance, this patch cable eliminates the need for expensive proprietary solutions while maintaining compatibility with standard fiber optic infrastructure. Free standard shipping on orders over $99 makes upgrading your network infrastructure cost-effective.
