The JBX43380 45-meter SC/APC to ST/UPC simplex singlemode fiber patch cable represents premium connectivity for demanding telecommunications and data center environments. Built to exacting standards, this cable features a 9/125 micron singlemode fiber core engineered for long-distance signal transmission with minimal loss and dispersion. Key Technical Features: This cable achieves ≤0.35dB insertion loss (0.15dB typical) and maintains return loss ≥20dB, ensuring signal integrity over extended distances. The fiber meets G.657.A1 specifications, providing enhanced bend performance for installation flexibility. Attenuation performance of 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm supports both legacy and modern wavelength-division multiplexing applications. Connector Specifications: The SC/APC (Angled Physical Contact) termination on the source end offers superior return loss characteristics, while the ST/UPC (Straight Physical Contact) termination on the receiving end provides universal compatibility. The simplex configuration enables unidirectional signal transmission, ideal for applications where separate receive and transmit paths are required. Built for Installation and Compliance: The yellow OFNR (Optical Fiber Nonconductive, Riser Rated) jacket provides flame resistance suitable for building riser installations while the 1.8mm outside diameter minimizes cable management space. RoHS and ELV compliant, this cable meets EU Directive 2002/95/EC requirements. TAA compliance makes it eligible for government procurement and federal projects. Applications: Perfect for telecommunications networks, ISP backhaul, data center interconnects, long-distance campus networks, and professional broadcast facilities. The 45-meter length accommodates substantial runs while maintaining signal quality. Customization Available: Beyond the standard 45m configuration, custom lengths are available to match your exact installation requirements. Warranty & Support: Backed by a 90-day limited warranty and shipped from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) for rapid delivery. Free standard shipping on orders exceeding $99.
