The JBX90200 45-meter SC/ST duplex singlemode fiber patch cable represents a professional-grade solution for organizations requiring dependable, high-speed fiber optic connectivity. Manufactured to exacting standards and available from multiple U.S. locations, this cable combines superior performance with regulatory compliance. **Technical Excellence:** Built with 9/125 singlemode glass fiber (G.657.A1 specification), this duplex cable delivers industry-leading performance metrics. Insertion loss remains exceptionally low at ≤0.35dB with typical performance of just 0.15dB, while return loss exceeds 20dB—ensuring minimal signal degradation over the 45-meter span. Attenuation specifications of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm support both legacy and modern wavelength division multiplexing applications. **Connector Configuration:** The SC/UPC to ST/UPC connection provides Type A to B crossover polarity—the most common configuration for duplex patch cord applications. This standard setup eliminates compatibility concerns in typical network deployments while maintaining optimal signal integrity. **Safety & Compliance:** OFNR (Outdoor Fiber Non-conductive Riser) jacketing ensures this cable meets fire safety requirements for installation in vertical runs and plenum spaces. Full TAA compliance satisfies government procurement requirements, while RoHS/ELV directives confirm environmental responsibility and hazardous substance restrictions. **Applications & Benefits:** Ideal for data centers, telecommunications infrastructure, enterprise networks, and backbone connections requiring single-mode fiber performance. The 45-meter length accommodates medium-distance runs while maintaining signal quality. Custom length availability addresses unique installation requirements. **Quality Assurance:** Tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, every cable undergoes rigorous attenuation verification. A 90-day limited warranty provides peace of mind, while free standard shipping on orders exceeding $99 offers cost-effective procurement. **Care & Installation:** Handle connectors with care to prevent dust contamination. Clean SC and ST connection points before mating using appropriate fiber optic cleaning supplies. Route cables away from EMI sources and avoid sharp bends that exceed the cable's bend radius specifications.
