The JBX92189 7-meter SC/ST duplex singlemode fiber patch cable represents a premium solution for professional fiber optic network installations. Built to exacting standards, this cable delivers the performance and reliability demanded by telecommunications, data center, and enterprise environments. Key Technical Specifications: This duplex patch cable features a 9/125 micron singlemode core with G.657.A1 glass fiber, supporting both 1310 nm and 1550 nm transmission windows. The cable achieves exceptional low insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB, ensuring minimal signal degradation. Attenuation rates are optimized at 0.25 dB/km (1310 nm) and 0.35 dB/km (1550 nm), enabling reliable long-distance signal transmission. Construction and Safety: The 1.8mm outside diameter provides optimal balance between flexibility and durability. The OFNR (Optical Fiber Non-Conductive Riser Rated) jacketing ensures flame resistance and safety in vertical cable runs. RoHS and ELV compliant, this cable meets EU directive 2002/95/EC requirements, making it suitable for environmentally conscious organizations. Connectivity and Compatibility: Features SC/UPC and ST/UPC connectors with Type A to B crossover polarity—the industry standard configuration for duplex patch cords. This ensures seamless compatibility with existing network infrastructure and eliminates connectivity issues. Compliance and Warranty: TAA (Trade Agreements Act) compliant, making it suitable for government and federal projects. All cables are attenuation tested per ANSI/TIA/EIA-455-171-A-2001 standards and backed by a 90-day limited warranty. Free standard shipping on orders exceeding $99, with domestic inventory in California, Texas, and South Carolina enabling rapid deployment. Applications: Ideal for fiber backbone connections, server-to-switch connections in data centers, long-distance telecommunications links, and network upgrades requiring superior signal integrity. Custom lengths available to meet specific installation requirements.
