The JBX42207 80-meter LC/APC to FC/UPC Duplex Singlemode Fiber Patch Cable represents premium connectivity for demanding fiber optic applications. Designed with precision engineering and tested to industry standards, this cable bridges the gap between LC/APC and FC/UPC connector types—two of the most prevalent connector standards in telecommunications infrastructure. **Technical Excellence** This duplex patch cable features 9/125 singlemode fiber (G.657.A1 grade), the industry standard for long-distance, low-attenuation signal transmission. The 80-meter length accommodates extensive installation distances while maintaining signal quality. With an insertion loss of just 0.15dB typical (≤0.35dB maximum) and return loss exceeding 20dB, this cable minimizes signal degradation and ensures reliable data transmission at both 1310nm and 1550nm wavelengths—the primary telecommunications bands. **Superior Construction** The cable features a 1.8mm outer diameter with OFNR (Optical Fiber Non-conductive Riser) jacketing, meeting fire safety codes for building installations. The plastic accessory materials ensure lightweight, flexible installation in tight spaces while maintaining structural integrity. The bright yellow outer jacket facilitates quick identification and organized cable management in complex network environments. **Compliance & Certification** Fully TAA compliant, this cable meets federal procurement standards required by government agencies and institutions. RoHS/ELV directive compliance ensures environmental responsibility. Manufacturing occurs across multiple facilities (Taiwan, United States, China) with quality control ensuring consistent performance. **Practical Applications** Ideal for data center interconnects, telecommunications networks, enterprise installations, and any application requiring reliable duplex singlemode connectivity. The Type A to B crossover configuration is the standard for duplex patch cords, eliminating compatibility concerns. **Value Proposition** With free standard shipping on orders exceeding $99, custom length availability, and a 90-day limited warranty, this solution provides exceptional value. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) ensuring rapid delivery. Whether upgrading existing infrastructure or building new networks, the JBX42207 delivers professional-grade performance at competitive pricing.
