The JBX87187 represents a premium solution for singlemode fiber connectivity, engineered to meet the rigorous demands of modern telecommunications infrastructure. At 5 meters in length, this duplex patch cable provides an ideal bridge length for interconnecting network equipment in rack environments, telecommunications closets, and distributed antenna systems. **Technical Specifications:** This cable features a 9/125 singlemode core constructed with G.657.A1 glass fiber, the industry standard for long-distance signal transmission. The cable exhibits exceptional performance characteristics: insertion loss remains at or below 0.35dB (typical 0.15dB) and return loss exceeds 20dB, both critical metrics for maintaining signal integrity. Testing was conducted in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. The attenuation rate of 0.25dB/km at 1310nm or 0.35dB/km at 1550nm ensures minimal signal degradation over distance. **Compliance & Durability:** TAA-compliant construction makes this cable suitable for U.S. government and federal contracting applications. The cable meets RoHS Directive 2002/95/EC and ELV requirements, ensuring environmental responsibility without compromising performance. The OFNR (Optical Fiber Non-conductive Riser) rating permits installation in vertical cable runs between floors, making it versatile for building infrastructure. The outer diameter of 1.8mm provides bendability for space-constrained installations while maintaining structural integrity. **Connector Configuration:** SC/UPC to ST/UPC connectors with Type A to B crossover configuration represent the most common duplex setup in legacy and modern networks. SC connectors offer push-pull engagement, while ST connectors provide bayonet-style security—combining the best aspects of both connector types. **Applications:** Ideally suited for telecommunications hubs, data center interconnects, enterprise LAN backbones, and fiber-to-the-premise installations. The cable works seamlessly with network switches, routers, fiber optic multiplexers, and other professional-grade equipment. **Warranty & Support:** Backed by a 90-day limited warranty, with free standard shipping on qualifying orders. Available in custom lengths for specific installation requirements. Ships from multiple U.S. locations for expedited delivery.
