The JBX89191 represents a professional-grade solution for fiber optic network connectivity, specifically designed for telecommunications infrastructure, data centers, and enterprise networking environments. This 9-meter SC/ST duplex singlemode patch cable combines exceptional performance with regulatory compliance, making it an ideal choice for organizations prioritizing reliability and standards adherence. Key Technical Specifications: The cable features a 9/125 singlemode fiber core constructed with G.657.A1 glass fiber, optimized for both 1310nm and 1550nm wavelengths. Attenuation performance meets demanding standards at both wavelengths (0.25 dB/km at 1310nm, 0.35 dB/km at 1550nm). With typical insertion loss of just 0.15dB and return loss exceeding 20dB, this cable delivers superior signal quality essential for long-distance telecommunications. Connectivity and Compatibility: Equipped with SC/UPC connectors on one end and ST/UPC connectors on the other in Type A to B crossover configuration, this duplex cable accommodates standard network switching equipment. The dual fiber strands enable simultaneous bidirectional communication, critical for modern networking protocols. Construction and Durability: The 1.8mm outside diameter OFNR riser-rated jacketing provides flame resistance and durability in vertical plenum installations. The purple jacket aids in cable identification and organization within network infrastructure. Custom lengths are available to accommodate specific installation requirements. Compliance and Quality Assurance: Fully TAA compliant and RoHS/ELV certified, this cable meets EU directive 2002/95/EC requirements. Attenuation testing conforms to ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent quality. The product includes a 90-day limited warranty and ships from strategically located US facilities (Danville CA, Fort Worth TX, Beaufort SC). Applications: Ideal for connecting network switches, routers, and telecommunications equipment requiring high-speed, low-loss fiber connectivity. Perfect for backbone installations, data center interconnections, and campus network deployments where singlemode performance is essential.
