The JBX43327 80-meter SC/APC to FC/UPC simplex singlemode fiber patch cable represents a professional-grade solution for connecting fiber optic networks with precision and reliability. This single-strand configuration is specifically engineered for unidirectional signal transmission in demanding telecommunications and data center applications. **Technical Specifications:** Featuring a 9/125 micrometer singlemode fiber core, this cable meets G.657.A1 glass standards and delivers exceptional performance across standard telecommunications wavelengths. Attenuation is measured at 0.25 dB/km (1310 nm) or 0.35 dB/km (1550 nm), with insertion loss of ≤0.35dB typical (0.15dB). Return loss performance exceeds 20dB, ensuring minimal signal reflection and maximum data integrity. **Design & Construction:** The cable features a bright yellow polyurethane OFNR (Optical Fiber, Non-conductive, Riser) jacketing with 1.8mm outside diameter, providing excellent abrasion resistance and flame resistance for indoor riser installations. The color coding facilitates quick identification in complex fiber routing environments. **Compliance & Quality:** Fully TAA (Trade Agreements Act) compliant with RoHS/ELV certification, this cable meets EU Directive 2002/95/EC requirements. All connections are tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent quality and performance. **Practical Advantages:** The 80-meter length accommodates extended runs typical in enterprise networks and data center installations. Custom lengths are available for specialized applications. Includes a 90-day limited warranty, backed by multiple U.S. fulfillment locations for fast delivery. Free standard shipping applies to orders exceeding $99. **Applications:** Ideal for telecommunications networks, ISP infrastructure, data center connectivity, long-distance signal transmission, and enterprise fiber backbone installations. The simplex configuration suits applications requiring unidirectional signal flow, common in specialized networking topologies and equipment interface connections.
