The JBX42252 LC/APC to ST/UPC Duplex Singlemode Fiber Patch Cable represents the ideal solution for high-performance fiber optic network installations. Manufactured to exacting standards and available from multiple U.S. locations, this 10-meter cable combines reliability with cost-effectiveness. **Key Technical Features:** This duplex patch cable utilizes 9/125 singlemode fiber with advanced G.657.A1 specifications, supporting both 1310nm and 1550nm wavelengths. The cable achieves exceptional attenuation performance (0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm) and maintains insertion loss of ≤0.35dB with typical performance at just 0.15dB. Return loss exceeds 20dB, ensuring signal integrity for critical applications. **Build Quality & Compliance:** The yellow OFNR (Optical Fiber Non-conductive Riser) jacket rating ensures code compliance for vertical cable runs in commercial buildings. All connections are precision-polished and tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. TAA compliance certification makes this cable suitable for government and institutional procurements. RoHS and EU directive 2002/95/EC compliance confirms environmental responsibility. **Installation & Compatibility:** The LC/APC connector provides angle-polished termination for minimal back-reflection, while ST/UPC offers reliable mechanical connection. Type A to B crossover polarity is standard for duplex patch cords, eliminating compatibility concerns. The compact 1.8mm outer diameter fits easily through cable trays and conduit. **Value Proposition:** Custom length availability accommodates unique installation requirements without premium pricing. Free standard shipping on orders exceeding $99 and 90-day limited warranty provide peace of mind. Whether upgrading legacy networks or deploying new infrastructure, this TAA-compliant cable delivers enterprise-grade performance at competitive pricing.
