The JBX86187 5-meter SC/ST Duplex Singlemode Fiber Patch Cable represents premium optical connectivity for professional networking environments. Engineered with precision-grade 9/125 singlemode fiber core and advanced G.657.A1 glass composition, this cable delivers the performance standards required by telecommunications carriers, data centers, and enterprise networks. Optical Performance Excellence: This patch cable achieves exceptional attenuation characteristics, with measured performance of 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm, ensuring minimal signal loss over the 5-meter length. The typical insertion loss of just 0.15dB and guaranteed maximum of ≤0.35dB, combined with return loss exceeding 20dB, makes this cable ideal for long-distance and high-speed data transmission applications. Connector Specifications: The SC/UPC to ST/UPC connector configuration with Type A to B crossover polarity is the most common duplex patch cord standard. Both connector types feature ultra-polished ceramic ferrules for reliable low-loss connections and minimal reflectance. The duplex (two-strand) construction enables simultaneous bidirectional communication, essential for full-duplex network protocols. Compliance and Safety: TAA (Trade Agreements Act) compliant manufacturing ensures procurement eligibility for U.S. government contracts and installations. RoHS (Restriction of Hazardous Substances) and ELV compliance adheres to EU Directive 2002/95/EC, eliminating lead, mercury, cadmium, and other toxic materials. OFNR (Optical Fiber Non-conductive Riser) jacketing provides fire safety ratings required in vertical cable runs within buildings. Applications and Use Cases: Ideal for telecommunications facilities, data center backbones, campus networks, and fiber-to-the-desktop installations. The 5-meter length suits medium-distance runs between network equipment, optical distribution frames, and patch panels. Custom lengths are available for specialized requirements. Durable Construction and Warranty: With 1.8mm outer diameter and protective plastic accessories, the cable resists physical damage during installation and operation. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) ensuring rapid delivery. All units include a 90-day limited warranty and free standard shipping on orders exceeding $99.
