The JBX93205 70m SC/ST Duplex Singlemode Fiber Patch Cable represents professional-grade connectivity for demanding network applications. Constructed with precision-engineered 9/125 micrometer singlemode fiber and G.657.A1 glass fiber composition, this cable delivers the performance characteristics required for long-distance telecommunications, data center interconnects, and carrier-grade network infrastructure. Key Technical Specifications: The cable features SC/UPC to ST/UPC connectors configured in Type A to B crossover polarity, the industry-standard configuration for duplex patch cord applications. With a low outer diameter of 1.8mm and duplex construction, installation in cable trays, conduits, and patch panels is straightforward and space-efficient. Performance testing confirms insertion loss of ≤0.35dB (0.15dB typical) and return loss ≥20dB, meeting rigorous ANSI/TIA/EIA-455-171-A-2001 standards. Attenuation Performance: The cable maintains exceptional signal clarity across standard operating wavelengths: 1310nm at 0.25dB/km and 1550nm at 0.35dB/km. This performance ensures reliable transmission over the full 70-meter distance with minimal signal degradation, critical for applications requiring consistent data integrity. Compliance and Safety: TAA compliance and RoHS/ELV certification ensure this cable meets government procurement requirements and environmental standards. The OFNR (Optical Fiber Non-Conductive Riser) jacketing provides fire safety suitable for vertical cable runs in commercial buildings while maintaining environmental compatibility. Customization and Availability: While this product is available in the standard 70m configuration, custom lengths are available to meet specific installation requirements. The cable ships from multiple US locations (Danville CA, Fort Worth TX, and Beaufort SC) with free standard shipping on orders exceeding $99. Ideal Applications: Perfect for telecommunications infrastructure, data center interconnects, enterprise networking, disaster recovery site connections, and any application requiring single-mode fiber transmission over extended distances. The duplex configuration supports bidirectional communication, making it suitable for full-duplex network applications. The 90-day limited warranty provides peace of mind, while custom length availability ensures this solution adapts to your specific deployment needs. For enterprises and service providers requiring reliable, standards-compliant singlemode fiber connectivity, the JBX93205 delivers professional performance at competitive pricing.
