The JBX43411 represents a premium solution for fiber optic connectivity in professional networking environments. This 50-meter SC/APC to ST/APC simplex singlemode patch cable combines industry-leading performance specifications with cost-effective reliability, making it an excellent choice for telecommunications providers, data centers, and enterprise IT departments. **Technical Excellence**: Built with 9/125 singlemode fiber and G.657.A1 glass composition, this cable supports both 1310nm and 1550nm wavelengths with minimal attenuation (0.25 dB/km at 1310nm, 0.35 dB/km at 1550nm). The insertion loss of ≤0.35dB and return loss of ≥20dB ensure signal integrity over extended distances, critical for high-speed data transmission and telecommunications applications. **Compliance and Standards**: TAA compliance satisfies federal procurement requirements, while RoHS/ELV directives guarantee environmental responsibility. Attenuation testing per ANSI/TIA/EIA-455-171-A standards confirms performance reliability. The OFNR riser-rated jacket meets building code requirements for in-building installations. **Practical Design Features**: The distinctive yellow jacket facilitates easy identification and management in complex cable environments. The 1.8mm outer diameter enables flexible routing through conduit and cable trays. Straight-through polarity simplifies network configuration while maintaining optical performance. **Applications**: Perfect for campus networks, data center interconnections, long-haul telecommunications, broadcast facilities, and any application requiring single-mode fiber performance. The cable's 50-meter length provides substantial reach while maintaining signal quality. **Flexibility**: Custom lengths are available for specialized installations. The cable ships from three U.S. locations (California, Texas, South Carolina) for rapid delivery. Orders exceeding $99 qualify for free standard shipping. **Warranty and Support**: A 90-day limited warranty provides peace of mind for installation and operational phases. The product's compliance with multiple standards ensures compatibility with diverse network equipment and infrastructure. This patch cable represents an investment in network reliability and long-term performance for mission-critical applications.
