The JBX87205 SC/ST duplex singlemode fiber patch cable represents enterprise-class connectivity for telecommunications, data centers, and mission-critical network environments. At 70 meters, this cable provides extended reach capabilities while maintaining superior optical performance characteristics. Technical Excellence: This duplex patch cable features a precision-engineered 9/125 singlemode core with G.657.A1 rated glass fiber—the industry standard for demanding applications. The cable achieves exceptional insertion loss specifications of ≤0.35dB at 0.15dB typical, with return loss ≥20dB, ensuring minimal signal degradation over extended distances. Attenuation performance is rated at 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm, meeting rigorous ANSI/TIA/EIA-455-171-A-2001 standards. Connector Specifications: SC/UPC to ST/UPC connectors provide industry-standard compatibility with existing network infrastructure. The Type A to B crossover polarity configuration is optimal for duplex applications, simplifying network configuration and reducing installation errors. Compliance & Durability: TAA compliance ensures this cable meets U.S. government procurement requirements, while RoHS/ELV certification guarantees environmental responsibility. The riser-rated OFNR jacketing delivers fire safety certification necessary for in-building installations, protecting network infrastructure while meeting building codes. Applications: Ideal for fiber optic backbone connections, telecommunications equipment interconnect, data center migrations, and long-distance signal transmission where signal integrity is paramount. Customization & Support: Available in custom lengths for tailored network solutions. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. 90-day limited warranty provides peace of mind for critical installations.
