The JBX92187 5-Meter SC/ST Duplex Singlemode Fiber Patch Cable is engineered for telecommunications professionals and network administrators requiring dependable, standards-compliant fiber connectivity solutions. **Technical Excellence** This duplex patch cable utilizes 9/125 singlemode fiber with G.657.A1 glass composition, specifically designed for long-distance signal transmission with minimal loss. The cable delivers exceptional performance metrics: insertion loss as low as 0.15dB typical (≤0.35dB maximum), return loss ≥20dB, and attenuation of just 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm wavelengths. All specifications are verified to ANSI/TIA/EIA-455-171-A-2001 standards. **Professional-Grade Construction** Featuring precision SC/UPC to ST/UPC connectors with Type A to B crossover configuration (the industry standard for duplex patch cords), this cable ensures optimal signal integrity. The 1.8mm diameter OFNR riser-rated jacket provides durability while meeting building code requirements for in-wall installations. **Compliance & Reliability** TAA compliant and RoHS/ELV certified, this cable meets government procurement requirements and environmental regulations. Each unit includes a 90-day limited warranty and is manufactured in Taiwan, the United States, or China to ensure consistent quality. **Ideal Applications** - Backbone network connectivity - Data center fiber infrastructure - Telecommunications installations - Long-distance signal transmission - Mixed SC/ST network environments **Convenient Availability** With free standard shipping on orders exceeding $99 and rapid fulfillment from multiple U.S. distribution centers (Danville CA, Fort Worth TX, Beaufort SC), this cable arrives quickly. Custom lengths are available for specialized installations. **Why Choose This Cable?** While standard copper cabling limits bandwidth and distance, singlemode fiber provides unlimited throughput over extended distances without signal degradation. The SC/ST connector combination accommodates mixed environments where both connector types are deployed, making this cable invaluable for network upgrades and expansions. Professional-grade specifications ensure years of reliable service in mission-critical applications.
