The JBX91185 3-meter SC/ST duplex singlemode fiber patch cable represents professional-grade fiber connectivity engineered for demanding telecommunications and data center environments. This high-performance optical accessory combines precise engineering with stringent quality standards to ensure reliable signal transmission in mission-critical applications. **Technical Specifications:** Constructed with G.657.A1 singlemode fiber featuring a 9/125 micron core, this cable delivers superior signal integrity over extended distances. The SC/UPC to ST/UPC connector configuration in Type A to B crossover polarity represents the industry standard for duplex patch cord applications. Attenuation performance of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensures minimal signal loss across standard telecommunications wavelengths. **Performance & Compliance:** With insertion loss rated at ≤0.35dB (typical 0.15dB) and return loss ≥20dB, this cable meets rigorous performance benchmarks. Riser-rated OFNR jacketing provides building code compliance while maintaining signal quality. Full TAA compliance and RoHS/ELV certification make this cable eligible for government and enterprise procurement. **Quality & Reliability:** Every cable undergoes attenuation testing per ANSI/TIA/EIA-455-171-A standards, ensuring consistent performance. The 1.8mm outside diameter allows for easy routing through cable trays and conduit systems. Custom lengths available for specific installation requirements. **Ideal Applications:** - Telecommunications backbone networks - Data center interconnections - Fiber-to-the-desktop installations - Enterprise campus networks - Long-distance signal transmission Shipped from multiple U.S. distribution centers (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders over $99. Backed by 90-day limited warranty and available in custom configurations for specialized requirements.
