The JBX43209 90-meter LC/APC to FC/UPC simplex singlemode fiber patch cable represents a premium solution for professional fiber optic installations requiring exceptional reliability and performance. This comprehensive guide covers all aspects of this critical networking component. **Technical Excellence** Built with 9/125 singlemode fiber conforming to G.657.A1 standards, this cable delivers superior signal transmission characteristics. The insertion loss specification of ≤0.35dB (0.15dB typical) and return loss of ≥20dB exceeds industry standards, ensuring minimal signal degradation over extended runs. Attenuation testing follows ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent performance across the 1310nm and 1550nm wavelength windows. **Connector Architecture** The LC/APC to FC/UPC connector combination provides versatile compatibility across diverse network topologies. LC/APC connectors feature angled physical contacts that minimize back-reflection, while FC/UPC connectors offer mechanical reliability in high-vibration environments. The straight-through polarity configuration supports standard bidirectional applications. **Installation & Durability** The 1.8mm outside diameter yellow OFNR (Optical Fiber Non-conductive Riser) jacket ensures compliance with building fire codes while providing excellent tensile strength and flexibility for installation in cable trays and conduits. Ships from strategically located U.S. warehouses (Danville CA, Fort Worth TX, Beaufort SC) ensuring rapid delivery. **Compliance & Standards** TAA-compliant certification makes this cable ideal for federal government and GSA contract procurement. RoHS/ELV directive compliance ensures environmental responsibility. Custom lengths are available for specialized installations, with standard packaging in quantities of 10 units per carton. **Applications** Ideal for telecommunications infrastructure, data center interconnects, enterprise network deployments, and any mission-critical single-strand fiber applications. The 90-meter length supports building-to-building connections and extensive intra-facility runs. **Warranty & Support** Backed by a 90-day limited warranty with free standard shipping on orders exceeding $99. Professional-grade quality suitable for telecommunications professionals and network infrastructure specialists.
