The JBX93202 55m SC/ST Duplex Singlemode Fiber Patch Cable represents professional-grade connectivity for telecommunications, data center, and enterprise network applications. This carefully engineered optical cable combines precision manufacturing with rigorous quality testing to deliver reliable, high-performance fiber optic signal transmission. **Technical Excellence:** Built on proven 9/125 singlemode fiber core technology, this cable supports long-distance transmission with minimal signal degradation. The G.657.A1 fiber specification ensures optimal performance across standard operating wavelengths (1310nm and 1550nm), with attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm. Tested insertion loss of ≤0.35dB (typical 0.15dB) and return loss ≥20dB guarantee superior signal integrity for mission-critical applications. **Robust Construction:** The 1.8mm outer diameter provides excellent bend radius tolerance while maintaining durability. OFNR (Optical Fiber Nonconductive Riser-rated) jacketing ensures safe installation in plenum spaces and vertical runs within buildings. The orange jacket color aids quick identification and meets industry visibility standards. **Connector Configuration:** SC/UPC to ST/UPC connectors with Type A to B crossover polarity deliver the most common duplex patch cord configuration, ensuring seamless integration with existing network infrastructure. Both connector types feature Ultra-Physical Contact (UPC) polish for minimal return loss. **Compliance & Standards:** TAA (Trade Agreements Act) compliant for government and institutional procurement. RoHS and EU directive 2002/95/EC certified, eliminating hazardous substances. Performance tested to ANSI/TIA/EIA-455-171-A-2001 standards, confirming reliability and consistency. **Practical Benefits:** Available in custom lengths for specialized installations, with standard 55-meter configuration shipped from multiple US locations (California, Texas, South Carolina). Includes 90-day limited warranty and free standard shipping on orders exceeding $99. Compact 10x10x10 case packaging simplifies storage and transport. **Applications:** Ideal for telecommunications networks, data center backbone connections, long-distance signal transmission, broadcast facilities, and enterprise LAN/WAN installations. Perfect for environments requiring single-mode performance, extended reach, and superior signal fidelity.
