The JBX43384 is a premium 65-meter SC/APC to ST/UPC simplex singlemode fiber patch cable designed for mission-critical telecommunications and data center applications. This professional-grade interconnect solution combines superior performance specifications with practical installation features, making it an ideal choice for network engineers and IT professionals. **Technical Excellence** Manufactured with G.657.A1 grade optical fiber, this cable features a 9/125 micrometer core optimized for singlemode operation. The exceptional insertion loss specification of ≤0.35dB (0.15dB typical) and return loss ≥20dB ensures minimal signal degradation across the 65-meter span. These performance metrics have been rigorously tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing reliable attenuation characteristics at both 1310nm and 1550nm wavelengths. **Installation and Compliance** The 1.8mm outside diameter cable jacket is OFNR (riser-rated), meeting strict fire-safety requirements for vertical installation and plenum use. TAA (Trade Agreements Act) compliance certifies suitability for government and federally-funded projects. The yellow jacket provides high visibility during installation and maintenance, reducing the risk of accidental damage or confusion in multi-cable environments. **Connector Configuration** The SC/APC (Angled Physical Contact) connector on one end pairs with an ST/UPC (Straight) connector on the other, providing versatility for interconnecting legacy systems with modern fiber infrastructure. Straight-through polarity ensures straightforward deployment without signal conversion complications. **Practical Benefits** Available in custom lengths beyond the standard 65m offering, this cable adapts to unique installation requirements. Free standard shipping on orders exceeding $99, combined with distribution from three US locations (Danville CA, Fort Worth TX, and Beaufort SC), ensures rapid delivery. The 90-day limited warranty provides peace-of-mind protection for your investment. **Applications** Ideally suited for telecommunications networks, data center interconnections, long-distance point-to-point fiber links, and telecommunications equipment upgrades. Commonly used in backbone cabling systems where singlemode performance and low attenuation are essential requirements. **Quality Assurance** Manufactured in Taiwan, US, or China with RoHS/ELV compliance, this cable meets rigorous environmental and safety standards. The harmonic code 8544.70.0000 classification confirms its status as a premium optical accessory designed for professional network infrastructure applications.
