The JBX42260 45-meter LC/APC to ST/UPC duplex singlemode fiber patch cable represents a professional-grade solution for critical fiber optic network applications. Designed with precision engineering and manufactured in compliance with international standards, this cable delivers reliable performance for telecommunications, data centers, and enterprise network environments. Technical Excellence and Performance: This singlemode fiber patch cable features a 9/125 micron core with G.657.A1 glass fiber construction, optimized for long-distance signal transmission with minimal signal degradation. The cable achieves exceptional insertion loss specifications of ≤0.35dB (with typical performance of 0.15dB) and maintains return loss ≥20dB, ensuring signal integrity across your network infrastructure. Attenuation testing complies with ANSI/TIA/EIA-455-171-A-2001 standards, with verified performance at both 1310nm and 1550nm wavelengths critical for modern optical networks. Connector Compatibility and Configuration: The LC/APC to ST/UPC duplex connector pairing accommodates Type A to B crossover polarity—the most common configuration for duplex patch cords. This versatile connector combination integrates seamlessly with existing network infrastructure while providing flexibility for various deployment scenarios. The 1.8mm outside diameter enables compatibility with standard fiber optic patch panels, wall-mounted termination boxes, and network equipment. Design and Installation Features: The distinctive yellow OFNR-rated (Riser Rated) jacket provides visual identification that simplifies network management and reduces installation errors in complex environments. The color-coding system is particularly valuable in data centers and telecommunications facilities where cable management is critical. The compact dimensions and flexible construction facilitate easy routing through cable trays, conduit, and wall spaces. Compliance and Quality Assurance: This cable is TAA (Trade Agreements Act) compliant and manufactured to meet RoHS/ELV directives, ensuring compliance with government procurement requirements and environmental regulations. The 90-day limited warranty backs every purchase, demonstrating manufacturer confidence in product quality. The cable is available in custom lengths to match your specific installation requirements, reducing waste and ensuring optimal fit. Applications and Use Cases: Ideal for telecommunications networks, enterprise data centers, campus-wide fiber installations, and mission-critical signal transmission. The singlemode construction supports long-distance transmission with minimal signal loss, making it suitable for applications ranging from short patch runs to extended network segments. Free standard shipping on orders over $99 makes this professional-grade cable an economical choice for both small installations and bulk deployments.
