The JBX86209 90-meter SC/ST duplex singlemode fiber patch cable represents a premium solution for professional fiber optic networking applications. Engineered to exacting telecommunications standards, this cable combines superior performance specifications with compliance certifications required by government and enterprise customers. **Technical Excellence:** Constructed with 9/125 singlemode fiber core and G.657.A1 glass fiber, this duplex patch cable delivers exceptional performance across critical transmission windows. The cable achieves typical insertion loss of just 0.15dB at 1310nm, rising to a maximum of 0.35dB at 1550nm, ensuring consistent, low-loss signal transmission over the full 90-meter span. Return loss specifications of ≥20dB guarantee minimal signal reflection and optimal signal integrity for sensitive telecommunications applications. **Compliance & Safety:** TAA compliance ensures this cable meets stringent government procurement requirements, while RoHS/ELV certification confirms lead-free, environmentally responsible manufacturing. The OFNR riser-rated jacketing provides superior fire resistance for vertical installations in buildings, meeting critical safety standards without additional conduit protection. **Connector Design:** The SC/UPC to ST/UPC connector configuration uses Type A to B crossover polarity, the industry standard for duplex patch cords. This crossover arrangement ensures proper signal routing and eliminates common installation errors, reducing troubleshooting time and improving network reliability. **Practical Applications:** Ideal for telecommunications infrastructure, data center interconnects, network equipment connections, and long-distance fiber backbone applications. The 1.8mm outside diameter provides excellent bendability for routing through tight spaces while maintaining performance specifications. **Quality Assurance:** Each cable undergoes attenuation testing per ANSI/TIA/EIA-455-171-A standards, ensuring consistent performance. The 90-day limited warranty protects your investment, backed by rapid shipping from multiple U.S. locations (Danville, CA; Fort Worth, TX; Beaufort, SC). **Custom Solutions Available:** If 90 meters exceeds your requirements, custom lengths are available. Free standard shipping on orders over $99 makes this enterprise-grade cable an economical choice for projects requiring reliability without premium costs.
