The JBX42080 represents a premium solution for fiber optic network connectivity, specifically designed for enterprises requiring reliable long-distance signal transmission. As a 45-meter duplex singlemode fiber patch cable, it bridges LC/APC and SC/UPC connectors with exceptional performance characteristics that exceed industry standards. **Technical Excellence**: Built with 9/125 singlemode fiber core and G.657.A1 glass fiber, this cable delivers attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm—well below typical requirements. The tested insertion loss of ≤0.35dB (with 0.15dB typical) ensures minimal signal degradation across extended distances, while ≥20dB return loss maintains signal integrity in bidirectional transmissions. **Regulatory Compliance**: This cable is fully TAA-compliant, meeting government procurement standards. It adheres to the EU RoHS directive (2002/95/EC) and carries ELV certification, making it suitable for regulated installations and secure environments. The OFNR (riser-rated) jacket classification permits installation in vertical pathways and non-plenum areas. **Practical Design Features**: The distinctive yellow jacket provides high visibility in cable management scenarios, reducing installation errors and facilitating maintenance. The duplex Type A to B crossover configuration represents the industry standard for patch cable applications. At 1.8mm outer diameter, the cable maintains flexibility for tight routing while protecting the internal optical strands. **Versatile Applications**: Ideal for data center migrations, telecommunications networks, fiber-to-the-premise (FTTP) installations, and enterprise backbone connections. The 45-meter length accommodates medium-distance runs without intermediate termination points. **Availability & Support**: Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on qualifying orders. Custom length options are available for specialized applications. Each cable comes with a comprehensive 90-day limited warranty and is manufactured to consistent standards across Taiwan, US, and China facilities. For critical network deployments, this cable delivers the performance, compliance, and reliability required by modern infrastructure.
