The JBX85188 3-meter SC/ST singlemode fiber patch cable represents a dependable solution for professional fiber optic network installations. Engineered to meet rigorous telecommunications standards, this duplex patch cord combines durability, performance, and compliance to support mission-critical data transmission. **Superior Fiber Optic Performance** Utilizing 9/125 micrometer singlemode fiber with G.657.A1 specification, this cable minimizes signal attenuation and maximizes transmission distance. With measured insertion loss of ≤0.35dB (typical 0.15dB) and return loss ≥20dB, it meets ANSI/TIA/EIA-455-171-A standards for predictable, consistent performance across 1310nm and 1550nm wavelengths. **Professional Design and Identification** The bright yellow OFNR (Optical Fiber Non-conductive Riser)-rated jacket provides excellent visibility during installation and maintenance, reducing the risk of connectivity errors. The duplex configuration with Type A to B crossover polarity ensures seamless integration into existing network infrastructure and supports bidirectional communication without additional adapters. **Enterprise and Government Compliance** TAA (Trade Agreements Act) compliant with RoHS/ELV certification, this patch cable meets stringent procurement requirements for government agencies, enterprises, and organizations prioritizing compliance and sustainability. The 1.8mm outside diameter ensures compatibility with standard fiber management systems while maintaining optimal bend performance. **Versatile Applications** Ideally suited for telecommunications facilities, data centers, campus networks, and broadcast facilities requiring reliable singlemode connectivity. The SC and ST connector combination provides flexibility for connecting diverse network equipment and infrastructure. **Customization and Convenience** While this product is available in the standard 3-meter length, custom lengths are available to match your specific installation requirements. With free standard shipping on orders over $99 and 90-day limited warranty coverage, this solution delivers exceptional value. **Specification Summary** • Fiber Type: 9/125 singlemode (G.657.A1) • Connectors: SC/UPC to ST/UPC • Length: 3 meters • Jacket: Yellow OFNR • Polarity: Type A to B Crossover • Attenuation: 1310nm: 0.25 dB/km | 1550nm: 0.35 dB/km • Return Loss: ≥20dB • Outside Diameter: 1.8mm • Certification: TAA, RoHS/ELV compliant • Warranty: 90 days limited Ships from multiple U.S. distribution centers including Danville, CA; Fort Worth, TX; and Beaufort, SC for rapid delivery to your location.
