The JBX43658 ST/APC to LC/UPC simplex singlemode fiber patch cable represents enterprise-class connectivity for mission-critical network infrastructure. This 85-meter cable is specifically engineered to meet the demanding requirements of modern datacenters, telecommunications facilities, and large-scale network deployments. Technical Excellence: With a 9/125 micrometer core and G.657.A1 bend-insensitive glass fiber, this cable delivers superior performance across standard telecommunications wavelengths. The insertion loss specification of ≤0.35dB (0.15dB typical) ensures minimal signal degradation, while return loss ≥20dB maintains signal integrity for critical applications. Attenuation performance meets ANSI/TIA/EIA-455-171-A-2001 standards at both 1310nm and 1550nm wavelengths. Compliance & Certifications: TAA compliance makes this cable suitable for government contracts and federal procurement requirements. RoHS/ELV certification ensures environmental responsibility and compliance with EU Directive 2002/95/EC. The riser-rated (OFNR) yellow jacket provides fire safety and plenum compliance for building-code requirements. Practical Design Features: The distinctive yellow jacket enables quick identification in complex cable installations, while the 1.8mm outer diameter maintains flexibility for tight routing scenarios. Simplex configuration supports single-direction signal transmission, ideal for dedicated backbone links and point-to-point connections. Applications: Perfect for datacenter interconnects, campus backbone networks, disaster recovery links, and long-distance fiber runs. The 85-meter length eliminates the need for splicing while remaining manageable for installation and troubleshooting. Value Proposition: Quality construction combines with competitive pricing and hassle-free shipping. The 90-day limited warranty provides peace of mind, while custom lengths are available for unique installation requirements. This cable represents the reliability enterprises demand from their fiber infrastructure.
