The JBX42536 75-meter ST/APC to ST/APC duplex singlemode fiber patch cable represents enterprise-class connectivity engineered for critical network applications. This premium patch cable combines proven ST/APC connector technology with singlemode fiber optics to deliver exceptional performance in long-distance telecommunications, data center interconnects, and carrier-grade network deployments. Key Technical Specifications: The cable features a 9/125 micrometer singlemode fiber core with G.657.A1 glass fiber composition, supporting both 1310nm and 1550nm wavelengths with attenuation rates of 0.25dB/km and 0.35dB/km respectively. The duplex configuration enables bidirectional communication through a single cable assembly, reducing installation complexity and space requirements. With ultra-low insertion loss of ≤0.35dB typical at 0.15dB and return loss exceeding 20dB, signal degradation is minimized across the entire 75-meter span. Design and Durability: The distinctive yellow jacket serves dual purposes—providing instant visual identification in crowded cable trays while maintaining OFNR (Optical Fiber Nonconductive Riser) rating for compliance with building safety codes. The 1.8mm outside diameter offers flexibility for cable management while the plastic accessory materials ensure durability. RoHS and ELV compliant, this cable meets EU directive 2002/95/EC environmental standards. Compliance and Certification: TAA (Trade Agreements Act) compliant for U.S. government purchasing, the JBX42536 adheres to stringent telecommunications standards including ANSI/TIA/EIA specifications. Attenuation testing confirms performance benchmarks critical for mission-critical applications. Applications: Ideal for telecommunications network expansion, data center backbone connections, campus network infrastructure, and carrier-class signal transmission where reliability and performance cannot be compromised. Customization Available: Requiring a different length? Custom cable configurations are available to match your specific deployment requirements. Warranty and Support: Backed by 90-day limited warranty with free standard shipping on orders exceeding $99.
