The JBX42995 70-meter LC/UPC singlemode fiber patch cable represents a dependable solution for professionals demanding precision-engineered connectivity. This simplex cable configuration features LC/UPC connectors at both terminations, delivering straight-through polarity for seamless integration into existing network infrastructure. Technical Excellence: This singlemode fiber cable utilizes a 9/125 core with G.657.A1 specification glass fiber, engineered specifically for single-mode light transmission. Tested to ANSI/TIA/EIA-455-171-A-2001 standards, the cable achieves exceptional performance metrics: insertion loss of ≤0.35dB (typical 0.15dB), return loss exceeding 20dB, and attenuation of 0.25dB/km at 1310nm or 0.35dB/km at 1550nm. These specifications ensure minimal signal degradation over the 70-meter span. Build Quality and Compliance: The yellow riser-rated (OFNR) jacket provides superior flame resistance and building code compliance while maintaining flexibility for installation in vertical cable runs. The 1.8mm outer diameter balances protection with space efficiency. RoHS/ELV compliant and TAA certified, this cable meets stringent regulatory requirements for government and enterprise procurement. Applications: Ideal for enterprise data centers, telecommunications closets, campus networks, and sensitive signal transmission environments requiring superior performance. The simplex configuration accommodates unidirectional signal transmission, typical in specialized monitoring and dedicated trunk applications. Customization and Support: Custom length options are available to accommodate specific installation requirements. Products ship from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. The 90-day limited warranty provides additional peace of mind for critical installations.
