The JBX89175 70-Meter SC/SC Duplex 9/125 Singlemode Fiber Patch Cable represents enterprise-class connectivity for telecommunications, data centers, and high-speed network applications. Engineered for demanding environments, this purple-jacketed cable delivers consistent performance across extended distances while maintaining industry-leading signal integrity. Technical Excellence: This duplex singlemode fiber cable features a 9/125 micrometer core, optimized for long-distance, single-wavelength transmission. The SC/UPC connectors employ Type A to B crossover polarity—the most common configuration for duplex patch cords—ensuring seamless integration with existing network infrastructure. Attenuation testing conducted per ANSI/TIA/EIA-455-171-A-2001 standards confirms ≤0.35dB insertion loss (0.15dB typical) and ≥20dB return loss, exceeding industry expectations for signal fidelity. Construction & Compliance: Manufactured with G.657.A1 glass fiber and OFNR (Optical Fiber Non-Conductive Riser) jacketing, this cable meets safety requirements for in-building installations. The 1.8mm outer diameter provides flexibility without compromising durability. RoHS/ELV compliance and TAA certification make this cable suitable for government, enterprise, and regulated procurement environments where material sourcing and environmental standards are critical. Applications: Ideal for connecting network switches, servers, and telecommunications equipment in data centers, telecommunications hubs, and enterprise networks. The 70-meter length accommodates long-run installations across building floors or between network closets. G.657.A1 fiber supports both 1310nm and 1550nm wavelengths, making it compatible with diverse optical systems. Value Proposition: Available in custom lengths for project-specific requirements. Free standard shipping on orders exceeding $99 reduces acquisition costs. 90-day limited warranty provides deployment confidence. Multiple manufacturing locations (Taiwan, US, China) ensure reliable supply chain and consistent quality control. This fiber patch cable represents a premium choice for organizations prioritizing signal integrity, regulatory compliance, and long-term network reliability.
