The JBX88110 45-meter SC/ST duplex singlemode fiber patch cable represents a professional-grade solution for organizations requiring robust, long-distance optical signal transmission. This cable is engineered to meet the stringent requirements of modern telecommunications infrastructure, data centers, and enterprise networking environments. **Core Technical Features:** Utilizing a 9/125 singlemode fiber core with G.657.A1 glass composition, this cable delivers superior performance characteristics. The ≤0.35dB insertion loss specification (with typical performance of 0.15dB) ensures minimal signal attenuation, critical for maintaining signal integrity across the 45-meter run. Return loss specifications of ≥20dB prevent reflective interference that could compromise data transmission quality. **Performance Specifications:** This cable has been rigorously tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. Attenuation performance is rated at 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm, making it suitable for both traditional and modern wavelength-division multiplexing applications. **Construction & Compliance:** The duplex configuration with SC/UPC to ST/UPC connectors supports Type A to B crossover polarity, the industry standard for duplex patch cords. The 1.8mm outer diameter jacket is OFNR (Optical Fiber Non-conductive Riser) rated, meeting fire safety requirements for in-building installations. Full RoHS/ELV and TAA compliance ensures suitability for government and regulated sector procurement. **Applications:** Ideal for telecommunications carrier networks, ISP backbone infrastructure, enterprise data center interconnects, campus area networks, and military/government installations requiring TAA-compliant components. **Advantages:** - Long 45-meter length minimizes splice points - Low insertion loss maintains signal quality - TAA compliance for government contracting - OFNR riser rating for safe in-building use - Custom lengths available for specialized applications - Free standard shipping on orders exceeding $99 - Backed by 90-day limited warranty - Manufactured across multiple facilities (TW, US, CN) **Packaging & Shipping:** Ships in professional packaging (10x10x10) from multiple US locations including Danville CA, Fort Worth TX, and Beaufort SC, ensuring rapid delivery to most continental locations.
