The JBX86205 70-meter SC/ST duplex singlemode fiber patch cable represents a professional-grade solution for demanding network infrastructure applications. Built with precision engineering and certified components, this cable delivers consistent performance for telecommunications, data centers, and enterprise networking environments. **Technical Specifications:** This duplex cable features a 9/125 micron singlemode core with G.657.A1 glass fiber construction, optimized for long-distance signal transmission. The cable exhibits exceptional optical performance with insertion loss of ≤0.35dB at 1550nm (0.15dB typical) and return loss exceeding 20dB. Attenuation is specified at 0.25 dB/km (1310nm) or 0.35 dB/km (1550nm), meeting ANSI/TIA/EIA-455-171-A-2001 standards. **Connector Configuration:** The SC/UPC to ST/UPC connectors utilize Type A to B crossover polarity—the industry standard for duplex patch cords. Both connector types feature UPC (Ultra Physical Contact) polishing for maximum performance and minimal signal loss. **Building Code Compliance:** Riser-rated (OFNR) jacketing ensures compliance with building fire codes, making this cable suitable for vertical runs and exposed installations. TAA compliance and RoHS/ELV certification confirm adherence to government procurement standards and environmental regulations. **Application Versatility:** Ideal for interconnecting fiber-optic network equipment across distances up to 70 meters, this cable supports numerous applications: backbone connections, data center links, campus networks, and telecommunications infrastructure. The 1.8mm outer diameter balances durability with space efficiency for cable tray routing. **Quality Assurance:** Every cable undergoes attenuation testing per ANSI standards. The 90-day limited warranty provides peace of mind, while free standard shipping on orders over $99 offers exceptional value. Available in custom lengths for specialized requirements, this product combines affordability with professional-grade reliability. Ships from multiple US locations for faster delivery.
