The JBX42443 60-meter FC/APC to FC/UPC duplex singlemode fiber patch cable represents a premium solution for enterprise-level optical network infrastructure. This cable is specifically designed for organizations requiring TAA compliance, including government agencies and contractors subject to Buy American provisions. **Technical Excellence**: The cable features a robust 9/125 singlemode core utilizing G.657.A1 glass fiber technology, delivering attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm. With insertion loss ratings of ≤0.35dB and return loss ≥20dB, this cable ensures minimal signal degradation over its 60-meter span, critical for maintaining data integrity in backbone and cross-connect applications. **Connector Configuration**: The FC/APC to FC/UPC configuration with Type A to B crossover polarity represents the industry standard for duplex patch cord applications, eliminating compatibility concerns in mixed-connector environments. FC connectors are renowned for their push-pull mating mechanism, providing secure connections resistant to vibration and accidental disconnection. **Build Quality & Compliance**: The 1.8mm diameter yellow OFNR (Optical Fiber Nonconductive Riser) rated jacket balances flexibility with durability, suitable for routing through cable trays, conduit, and vertical building runs. RoHS/ELV certification ensures environmental compliance, while TAA compliance opens access to government procurement channels. **Practical Advantages**: Available in custom lengths, this cable accommodates unique installation requirements without excess waste. Multiple U.S. fulfillment locations (California, Texas, South Carolina) ensure rapid delivery. The 90-day limited warranty provides peace of mind for mission-critical deployments. **Applications**: Ideal for data center interconnections, telecommunications infrastructure, enterprise campus networks, and government installations requiring standards-compliant components. The duplex configuration supports full-duplex communication, essential for modern network architectures.
