The JBX88286 represents a premium solution for singlemode fiber optic connectivity in professional networking environments. This 4-meter ST/ST duplex patch cable combines superior optical performance with rigorous compliance standards, making it an ideal choice for enterprises, data centers, telecommunications facilities, and government agencies. **Technical Excellence** Featuring a 9/125 micrometer singlemode core, this cable minimizes signal degradation over extended distances. The G.657.A1 specification glass fiber provides enhanced bending performance without compromising optical characteristics. Insertion loss measurements of ≤0.35dB (0.15dB typical) ensure minimal signal power loss, while return loss exceeding 20dB prevents signal reflections that could degrade system performance. These specifications are verified through rigorous testing in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. **Duplex Configuration Benefits** The duplex design incorporates ST/UPC to ST/UPC connectors with Type A to B crossover polarity—the industry standard for duplex patch cords. This configuration enables full-duplex communication, allowing simultaneous transmission and reception on a single cable, reducing installation complexity and space requirements. **Compliance & Safety** TAA (Trade Agreements Act) compliance qualifies this cable for government and federal agency procurement. RoHS certification and adherence to EU directive 2002/95/EC ensure environmental responsibility and chemical safety. The OFNR (Optical Fiber Non-conductive Riser) jacketing rating permits installation in vertical cable runs and plenums, meeting fire code requirements in commercial buildings. **Practical Advantages** The distinctive green jacket facilitates quick identification within cable management systems. At just 1.8mm outer diameter, the cable maintains flexibility for routing through tight spaces while protecting the delicate fiber core. Custom lengths are available for non-standard applications, and standard orders ship free from multiple US distribution centers (California, Texas, or South Carolina). **Applications** Ideal for backbone connections, inter-building links, data center patch panels, telecommunications equipment racks, and high-reliability network installations. The 4-meter length accommodates typical cabinet-to-cabinet distances without excess coiling. **Support & Warranty** Every cable includes a 90-day limited warranty, with technical support available for installation guidance and troubleshooting.
